How to Install JDK?

The following article provides an outline for Install JDK. The Java Development Kit (JDK) is helpful to write programs in Java. It is also known as the Java Platform Standard Edition (Java SE). JDK is an open-source software provided by Sun Microsystems, now taken over by Oracle, for anyone to use freely for programming.

Do many people have the question, JDK or JRE? So let us look at what each is used for. Java Runtime Environment (JRE) is required for running programs of Java, whereas JDK is required for writing and running the programs. JDK is a development kit containing JRE and the development tools (debugger and compiler) needed for getting a program output in Java. Simply put, JRE happens to be a subset of JDK; that is, it is included in JDK. Therefore, we will need to install JDK to write and run programs.

Web development, programming languages, Software testing & others

Installation Prerequisites of JDK

JDK has bare minimum requirements for disk space and RAM for the 64-bit Windows platform. It requires around 800 MB disk space to install JDK, as JRE also gets installed along with it. JDK requires 128 MB of memory space to run JDK successfully. This is the minimum RAM required for running basic and small programs, but as the size of an application increases, the memory requirement also increases for the application to run smoothly.

Step by Step Installation Of JDK

Before installing the latest JDK version, it is recommended to check our systems for any old JDK versions and uninstall them. Though we can have more than one JDK, it is easier to set paths and to work with just the latest one.

Step 1: Download JDK from the Site

  • Go to the Oracle site and open the Java SE download page. Under the latest version of Java Platform, Standard Edition, click on the JDK download button.

How to install the java software development kit

Next, click on the Accept License Agreement button and choose your version of Java for Windows (32-bit or 64-bit) to proceed with downloading the JDK executable file.

Step 2: Install the JDK exe File

  • In this step, we will be running the executable JDK file (It will be a file with .exe as an extension) once the download is done. This installs JDK as well as JRE. For running this file on Windows, we will need Administrator rights.
  • To begin the installation, we need to double-click on the downloaded file, and we will be presented with the below window.

How to install the java software development kit

  • Click on Next to proceed with the installation, and follow the Installation guide provided for any queries.
  • Click on the Close button once the installation has finished.

  • To recover some of our system’s disk space, it is good practice to delete the downloaded exe file once the download has been done.

Step 3: Check the Directory

  • JDK gets installed in the C directory of our system by default having the path “C:\Program Files\Java\jdk-11.0”. If we make any change to this path at all, we need to make a note of it as it will be required in the upcoming steps.
  • This is the directory structure for our example.

How to install the java software development kit

Step 4: Update the Environment Variables

  • We will need to update our system’s Environment variables with our installed JDK bin path to run the Java programs because while executing the programs, the command prompt will look for the complete JDK bin path.
  • The PATH variable in our system provides the exact location of executables that will be used for running Java programs, such as javac and java. The CLASSPATH variable provides us with the library files location.
  • If we do not set the PATH variable, we will specify the full path to the JDK bin every time we run a program.

For example: C:\> “C:\Program Files\Java\jdk-11.0\bin\javac” TestClass.java

  • So to set these variables, first right-click on My PC and select Properties.

How to install the java software development kit

  • Inside Properties, in the left-side panel, select Advanced System Settings, and here choose the option Environment Variables.

How to install the java software development kit

  • Click on New, and type PATH in the Variable Name, and enter the path of the bin of installed JDK in the Variable Value field.

How to install the java software development kit

  • If we already have the PATH variable, we can edit it by adding it to the existing values.
  • Click on the OK button to apply the changes.

Step 5: Verify the Java Installation

  • Open the command prompt and enter the command “java –version”, and if it runs successfully, Java has been successfully installed.
  • Now that we have seen the steps to install JDK, let the programming fun begin!

Java Training (40 Courses, 29 Projects, 4 Quizzes)

This section describes how to install and set up the development kit. It includes procedures for performing the following tasks:

Before Installing the Development Kit

Before installing the development kit, be sure to install the following software:

Java Development Kit (JDK) – The tools in this development kit were tested with JDK 7 and JDK 8 (32 bit and 64 bit versions). If you are planning to develop your own applications, you should use JDK 7. You can download and install the JDK release according to the instructions on the website:

GCC compiler – Minimal GNU for Windows (MinGW), version 4.8.1 or later is required to build the cref and tools from sources.

You can download MinGW from http://sourceforge.net/projects/mingw . For MinGW installation information, go to http://www.mingw.org .

Eclipse IDE (optional) – Using the Eclipse IDE as your development environment is recommended, although you can also run the samples and the development kit tools from the command line.

Download the Windows Eclipse IDE from the following URL and install it according to the instructions on the website:

Apache Ant – Most Eclipse distributions include Apache Ant. If you did not install Eclipse, you should install Apache Ant, as it is required to run the samples from command line and to build the cref from source code. Version 1.9.4 was used to test the release. You can download and install Apache Ant from http://ant.apache.org .

Installing the Development Kit

Follow these steps to install the development kit.

  1. Close Eclipse, if it is running.
  2. Download the Java Card Development Kit .msi file to a directory of your choice.
    • java_card_kit-classic-3_0_5- ux -win32-bin- do|gl -b NN – dd_mmm_yyyy .msi
  3. Run the downloaded .msi file from the directory.
    1. The Java Card Development Kit Setup Wizard starts. Follow the prompts and accept the License Agreement.
    2. Enter a directory where the files will be installed and follow the prompts to complete the process.

    The installation directory is referred to as JC_CLASSIC_HOME throughout the documentation.

    When the Java Card Development Kit has been installed, proceed to:

    Optional, but recommended. Install the Java Card plug-in for Eclipse. See Installing the Eclipse Plug-In

    Examine and run the samples. See Running the Samples

    Confirming System Variables

    Certain system variables are set during the installation process. If you are not able to build samples from the command line, or if something seems to be wrong with the Eclipse plug-in operation, verify that the following variables and paths are set correctly:

    • JAVA_HOME system variable should be set to the JDK software root directory and its bin\ in the PATH .
    • ANT_HOME system variable should be set to the Ant root directory and its bin\ in the PATH .
    • JC_CLASSIC_HOME variable should be set to the Java Card development kit root directory.
    • The Java Card development kit bin\ directory should be in the PATH .
    • The MinGW bin\ directory should be in the PATH . MinGW is only required if the Development Kit source bundle is installed.

    Java Development Kit(JDK) is a software development kit, which we are going to use to develop applications in Java programming language. Let us see how to set up, download and install JDK.

      In order to download and install JDK, you have to open the link to Oracle website and click on the download button, right under JDK(pointed by the mouse pointer in the picture below).

  4. Clicking on the download button takes you to a new page, where you are required to –
    • Accept License Agreement, and
    • Select the version of Java that matches your Operating System(OS), please see the next Figure 2.

    Ours is a 64-Bit Windows Operating System, hence we have clicked on the last option next to Windows x64(please look at the figure2), but if you have a 32-Bit Windows Operating System, you would need to click on Windows x86 option.

    As soon as you click on the version of JDK that you wish to install, a new window will pop-up on your screen, asking you to Save the file or Cancel the download, please click on Save and the JDK file will be downloaded.

    Once the JDK file is downloaded, you need to double click on it and you will be displayed an installation window, in which you need to click on the Next button.

  5. In the next installation window, you will asked to select the features of Java Development Kit(JDK) that you wish to install.
    • Select the feature – Development Tools.
    • By default, JDK will be installed in C:\Program Files\Java\jdk1.8.0_144 folder, but you can change the location by clicking on the Change button.

    We are going to install JDK in the its default location, hence we are just going to click the Next button on this window.

    In the next window, you are shown a progress bar, displaying the installation progress of Java.

    Once the installation is over, you are presented a window, displaying a message about the successful installation of JDK.

    Click on the Close button and that’s it! Java Development Kit(JDK) has successfully installed in our system. Like the tutorial? Yes? Please, share it or please like our social media channels. Thank you!

    This tutorial will guide you step by step how to download and install Java Development Kit (JDK) in Windows. The Java JDK allows you to develop Java applications and run them.

    If you installed multiple JDK versions on the same PC, we recommend that you install the only latest version of JDK. Before going to download. we need to have the following:

    1. Internet browsers like Firefox, Google Chrome, or Internet Explorer.

    2. Internet Connection to download and install.

    Download and Install Java JDK in Windows

    Follow all the below steps to complete the download and installation of Java Software Development Kit (JDK) in Windows:

    Steps:

    1. Visit the Oracle download page in your browser and download the latest version of JDK from the following link:
    https://www.oracle.com/technetwork/java/javase/downloads/index.html

    How to install the java software development kit

    2. Accept License Agreement and download the latest Java JDK for your version (64 bit) of java for Windows.

    How to install the java software development kit

    The type of installation may depend on your system requirements and platform that you will choose to install.

    Once the JDK exe file has been downloaded to your computer from the website, double click on the downloaded exe file and run the installation of Java software on your computer.

    3. You must follow all the instructions provided by the installation wizard.

    4. Once the installation process is completed, check the program files folder of C:/ Drive. This folder must contain a Java folder with JDK and JRE sub-folders.

    If you see these sub-folders in your C:/ Drive’s program files folder, it means that the installation of Java is completed. Now, you can delete the downloaded file to recover the disk space.

    5. In the third step, you will have to check the Java configuration to make sure that the Java files are identified by the computer or not.

    For this, you will have to set the PATH variable permanently for JDK 13 so that it is persistent after reboot.

    If you do not set the PATH variable, then you must have to specify the full path every time to execute program that you run it.

    C:> “C:\Program Files\Java\jdk-13\bin\javac” MyClass.java

    So, let’s set the full path in the system.

    How to set Path and Classpath in Environment Variables for Java?

    Once the Java Software Development Kit has been installed successfully, the next step is to set up Path and Classpath in environment variables permanently in your system.

    Environment variables are special Windows operating system variables that are used to identify the installation directory, location of temporary files, tools, and profile settings.

    They contain values that can be used by programs. Since the value of environment variable is changeable and updateable, environment variable is dynamic in nature.

    Some of the common environment variables are as follows:

    1. %appdata%: Location of Application Data folder for your user profile.
    2. %commonprogramfiles%: Location of Common Files folder, within the main Program Files folder.
    3. %path%: Location of various tools e.g. Java tools.
    4. %programfiles%: Location of where programs are installed.
    5. %temp%: Location of temporary files.
    6. %windir%: Location of windows system files.

    The Path variable gives the location of the bin folder and the Classpath variable gives the location of Java files.

    Whenever Java programs are compiled and executed on the computer, the computer needs to know where java files are located and what is respective PATH of bin folder?

    So, Java file location (library files) is provided through the ClASSPATH variable.

    Steps to set Path variable on Microsoft Windows

    Path variable gives the location of tools. Specifically, it identifies the location of Java compiler (Javac.exe) and java interpreter (Java.exe).

    There are two ways to set path variable that are as follows:

    1. Control Panel
    2. Command Line

    Setting Path using Control panel:

    Setting the Path variable using control panel is a superior way because it will be permanent. Follow all the steps below to set the PATH variable using the control panel on Microsoft Windows:

    1. Go to the Start menu and navigate to the Control panel.

    2. In the Control panel, you will see a System icon. Now double-click on this icon.

    3. Go to the Advanced system setting and click on it. You can see the below screenshot.

    How to install the java software development kit

    4. A system properties dialog window box will be displayed as shown in the below screenshot.

    How to install the java software development kit

    5. Click on the Environment variables.

    6. Now click on the New button in System variable. You will see a new window dialog box “New System Variable” as shown in the below screenshot.

    How to install the java software development kit

    7. Write “PATH” as a variable name and enter the location of the JDK bin folder in the variable value. A typical value for the PATH variable is shown below:

    Now click on the OK button.

    Note: In case you have already created a PATH variable in your system, edit the PATH variable to

    PATH = bin;%PATH%; Here, %PATH% join the existing path variable to our new value. You must have only one bin directory for a JDK in the path at a time.

    8. You can follow similar steps to set CLASSPATH. Write “CLASSPATH” as a variable name and enter the location of the JDK lib folder in the variable value.

    The following is a typical value for the CLASSPATH variable:

    Now click on OK button.

    Setting Path variable using Command Line:

    Setting Path variable using the command line is temporary. It can be set using SET command. The SET command is not case sensitive.

    This technique can apply only at the current command line. Let’s understand how to set Path variable at the command line.

    Similarly for classpath:

    Hope that this tutorial has covered almost all the important points to download and install Java Development Kit (JDK) on the computer system. I hope that you will have also understood how to set path in environment variables permanently.

    Posted by: Reshma Sathe in Core Java October 20th, 2020 0 Views

    In this article, we will see how to download and install Java Development Kit 13, which is a non-LTS version for a Windows system.

    You can also check how to install Java in the following video:

    1. Introduction

    Java was first released in 1996 and since then has become one of the most widely used object-oriented programming languages. The most recent version of Java is 15 with Java 16 in the works. In this article, we will download and install Java 13 which is a Non-LTS version.

    1.1 What is a Non-LTS version?

    • Starting Java version 8, Oracle has shifted its release timeline and the licenses under which Java is available. Java is now available under the 2 licenses.
      1. GNU General Public License v2 with Classpath exception (GPLv2+CPE) which is provided by OpenJDK builds.
      2. The commercial license under Oracle product or service i.e. Oracle Technology Network License Agreement (ONTLA). Users can still this version for free if they use it for personal use. For Production use, the organizations will need to pay for “Java SE subscriptions”.
    • Oracle has shifted from the 2-3 year release cycle to a 6-month cycle. This helps release changes/features faster and in an easy-to-adopt way.
    • Oracle will provide Long-term support(8 years or more) for a few versions called Long-Term Support(LTS) versions. Java 11 is the current LTS version. The next expected LTS version is Java 17.
    • All the versions in between, including Java 13, are non-LTS versions for which Oracle will not provide extended support.
    • More information about release cadence and licensing changes is available here.

    2. Download and Install Java Development Kit 13

    Depending upon the license you want to choose, there are 2 sites from where we can download Java. Oracle JDK is the enterprise version and the OpenJDK which is the open-source version. We will look at how to download and install Java JDK 13 from both.

    2.1 Oracle JDK

    The Oracle JDK is available under the Oracle Technology Network License Agreement (ONTLA) license and is the commercial version(Users and organizations can buy a subscription to get support from Oracle for the Java installation).

    2.1.1 Download

    • Java JDK 13 has now been superseded by Java 14 and 15. Hence to download Java 13, we need to go to the Java SE 13 Archive Downloads page.
    • On the Archive-Downloads page, scroll down to find the Windows x64 Installer and click on the executable file to download.
    • Login to your Oracle account and accept the license agreement. If you do not have an account, creating one is a simple and free-of-cost process.
    • The file downloaded is: jdk-13.0.2_windows-x64_bin.exe

    2.1.2 Install

    To install Java, click on the executable jdk-13.0.2_windows-x64_bin.exe that gets downloaded on your system. Follow the steps in the executable to install java on your system.

    2.2 OpenJDK

    The OpenJDK JDK is available under the GPLv2+CPE license and is the open-source version. Oracle does not provide commercial (subscription-based) support for the OpenJDK java distributions.

    2.2.1 Download

    • The latest version of java is java 15 and so to download JDK 13 we need to go to the Archived Release page.
    • Scroll down to the 13.0.2 build and click on the zip file for Windows.
    • The file downloaded is: openjdk-13.0.2_windows-x64_bin.zip

    2.2.2 Install

    To install the jdk , just extract the .zip file in the folder of your choice.

    3. PATH Variable

    After Java is installed, it is advisable to set the PATH variable with the path to the Java executables. Doing so enables java to be recognized across the system. There are 2 ways to set the path variable.

    3.1 Command Prompt(cmd)

    To set the PATH variable using cmd, Open cmd in the “Administrator” mode. Type the following commands and hit Enter.

    Open JDK: (path to the oracle jdk extracted folder)

    3.2 Environmental variables

    We can also set the path variable by using the environmental variables dialog.

    • In the “Type here to Search” box type in environment variables.
    • Click on the first option. This opens the System variables screen.
    • Click on the Environment variables button. This opens the environment variables dialog box.
    • Click on the PATH variables and then click on the Edit button.
    • In the dialog box that opens, put in the Java executable path and then click on OK.

    Oracle Java Development Kit:

    4. Verifying the installation

    There are 3 ways to verify that java is installed correctly.

    4.1 java -version command

    If the Java is installed and the PATH is set correctly, the java -version command should output the java JDK information along with the java version.

    4.2 where command

    If the Java is installed and the PATH is set correctly, the where the command outputs all the java executables present on the system.

    Command to type:

    4.3 Checking the installed folders/files

    Alternatively, we can also check the installed files/folders

    • For the Oracle JDK installation type “Programs” in the Type here to search box and then select the first option. This opens the “Apps and Features” dialog box. In the search box type in Java and this should output the Java version we just installed.
    • For the Open JDK, navigate to the extracted folder. Check if there is a bin folder with the java executables in it.

    5. Example Program

    To ensure that Java 13 is installed and running correctly, we will compile and run a program that uses one of the preview features of Java 13 called text blocks. To learn more about JEP 355. This feature is especially useful for building Html and JSON strings in java.

    In MultiLineStringsClass.java we will build a json-array using multi-line string block and display the same.

    In the Pre-Java-13 code we would build a json-array as follows

    Now Java 13 onwards, using the JEP355 feature we can write:

    The full source code is given below. MultiLineStringsClass.java

    To compile and run the program in command prompt with preview features enabled, we need to type in the following commands

    6. Summary

    The general opinion in the Java Developer community on upgrading to Java 13 is that developers should update to Java 13 on their systems and test their applications for compatibility with the newer features. This would greatly help transition to the next version when the next version is released. It is however not a good idea to put Java 13 in production since it is a non-LTS version.

    This tutorial has everything you need to know about installing JDK 8 on Windows.

    If you’re new to Java, I’ll show you how to setup the Java Development Kit.

    And if you’re a Java pro? I’ll highlight the needed links that you can use to download the installer.

    If you want to get up and running with Java, you’ll love this tutorial.

    Java is a computer programming language that is concurrent, class-based and object-oriented. Java applications compile to bytecode (class file) that can then run on a Java Virtual Machine (JVM).

    James Gosling created Java at Sun Microsystems. It is currently owned by the Oracle Corporation.

    Consult following posts if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.7, JDK 1.9 or JDK 1.10.

    Java can be obtained from the Oracle Java download page. There are a number of different Java packages available, for this tutorial we will be installing Java Standard Edition (SE) on Windows.

    In order to be able to compile Java code, we need the Java Development Kit (JDK) package that comes with a Java compiler. The JDK package also comes with a Java runtime environment (JRE) that is needed to run compiled Java code.

    Scroll to the Java SE 8u171/ 8u172 section in the middle of the Oracle Java download page and click on the Download button right below JDK . Then look for the Java SE Development Kit 8u172 section.

    Accept the License Agreement and pick the correct download for your operating system. In this example, we will use the Windows 64 bit version.

    How to install the java software development kit

    Sign in using your Oracle account (or create a new one) and the download should start. Once the download is complete, locate the jdk-8u172-windows-x64.exe file and double-click to run the installer.

    How to install the java software development kit

    Click Next and on the following screen optionally change the installation location by clicking on the Change. button. In this example the default install location of ‘C:\Program Files\Java\jdk1.8.0_172\’ was kept. From now on we will refer to this directory as: [java_install_dir] .

    How to install the java software development kit

    We will not install the public JRE as the JDK Development tools include a private JRE that can run developed code. Select the Public JRE dropdown and click on This feature will not be available. as shown below.

    How to install the java software development kit

    Click Next and then Close to finish installing Java.

    How to install the java software development kit

    In order for Java applications to be able to run we need to setup a ‘JAVA_HOME’ environment variable that will point to the Java installation directory. In addition, if we want to run Java commands from a command prompt we need to setup the ‘PATH’ environment variable to contain the Java bin directory.

    When using Windows the above parameters can be configured on the Environment Variables panel. Click on the Windows Start button and enter “ env ” without quotes as shown below.

    How to install the java software development kit

    Environment variables can be set at account level or at system level. For this example click on Edit environment variables for your account and following panel should appear.

    How to install the java software development kit

    Click on the New button and enter “ JAVA_HOME ” as variable name and the [java_install_dir] as variable value. In this tutorial the installation directory is ‘C:\Program Files\Java\jdk1.8.0_172’ . Click OK to to save.

    How to install the java software development kit

    Click on the New button and enter “ PATH ” as variable name and “ %JAVA_HOME%\bin ” as variable value. Click OK to save.

    Note that in case a ‘PATH’ variable is already present you can add “ ;%JAVA_HOME%\bin ” at the end of the variable value.

    How to install the java software development kit

    The result should be as shown below. Click OK to close the environment variables panel.

    How to install the java software development kit

    In order to test the above configuration, open a command prompt by clicking on the Windows Start button and typing “ cmd ” followed by pressing ENTER . A new command prompt should open in which the following command can be entered to verify the installed Java version:

    The result should be as shown below.

    Java is a general-purpose, object-oriented programming language used in different domains. To download Java, we need to download and install the JDK (Java Development Kit). It provides a run time environment for Java. It contains libraries and classes that are necessary to run a Java program. The latest version of JDK is 14. We can download and install multiple versions of JDK in a system. But we recommend you to install the latest version only. In this section, we will learn how to download and install the latest version of Java.

    Java provides the following three editions:

    • Java SE: In Java SE, SE stands for Standard Edition. It is used to develop stand-alone applications, such as desktop applications.
    • Java EE: In Java EE, EE stands for the Enterprise Edition. It is used to develop enterprise applications, such as web application, socket programming, etc.
    • Java ME: In Java ME, ME stands for Micro Edition. It is used to develop mobile applications and embedded devices software, such as set-top boxes, and other electronic devices.

    In this section, we are going to download the Java SE. Follow the steps given below to download the JDK.

    Step 1: Go through the link https://www.oracle.com/in/java/technologies/javase-downloads.html. You will land on the Java Standard Edition (SE) Downloads page.

    How to install the java software development kit

    Step 2: Click on the JDK Download link under the Oracle JDK section.

    How to install the java software development kit

    When we click on the link, shown above, we land on Java SE Development Kit 14 Download page that shows the JDK download link for the different operating systems.

    Step 3: Click on the JDK download link according to your operating system.

    In our case, we are using Windows operating system, so we are clicking on the jdk-14.0.1_windows-x64_bin.exe. It downloads the .exe file.

    If you want to download the zip file, click on the second link.

    Step 4: Check the box to accept the License Agreement. It activates the download button.

    How to install the java software development kit

    Step 5: Click on the Download jdk-14.0.1_windows-x64_bin.exe button. It starts downloading the JDK 14.

    How to install the java software development kit

    Step 6: Double click on the downloaded .exe file. It asks for changes on your computer. Click on the Yes button to run the setup.

    Step 7: In the installation wizard window, click on the Next button.

    How to install the java software development kit

    Step 8: Click on the Change button if you want to change the installation directory. By default, it installs JDK on the location C:\Program Files\Java\jdk-14.0.1. Otherwise, click on the Next button. It starts the installation of JDK.

    How to install the java software development kit

    Step 9: When Java is successfully installed on your system it shows a message Java SE Developments Kit 14.0.1 (64-bit) Successfully Installed. Click on the Close button.

    How to install the java software development kit

    We have installed Java successfully. To check the Java is successfully installed or not, follow the steps given below.

    Step 10: Go to the bin folder of the JDK and copy the path. In our case path is C:\Program Files\Java\jdk-14.0.1\bin.

    Step 11: Open the Command Prompt and type the following commands:

    How to install the java software development kit

    Step 12: Type the command java ?version to check the Java version. It ensures that Java is successfully installed in your system.

    My first programming language was Pascal and I did not have to install more than just the compiler. Same thing with C++, the environment was all set to write code by just installing Visual Studio. In the case of Java why do we need to install this Java Development Kit besides having the Eclipse, Netbeans or another compiler.

    I think that Python and Perl have also a packet to be installed before writing code in those languages. Otherwise we wouldn’t be able to start off. What do these packets contain and why some languages require these files to be installed before compiling any code.

    The normal Java package (the JRE) only contains the stuff necessary to run Java programmes. The JDK is the package containing the compiler. Based on your experience with Pascal and C++, you obviously understand why you need the compiler to create your own programmes.

    Eclipse and Netbeans are IDEs, Integrated Developement Enviroments. They make it easier for you to program, but they are not strictly needed, in the same way that you can write a program in C++ by just installing a C++ compiler and without using Visual Studio. There are many programmers, especially in the non-windows-world, who just use a text editor to write those programmes.

    As for Python and Perl, it’s the same thing. You need to install their respecitve interpreters to run programmes written in those languages. Without them, how do you expect the computer to understand what you want from it?

    If you want compare, for example, Eclipse and Visual Studio: the installation for Visual Studio contains both the IDE and the compiler. Eclipse is just the IDE. You also need to install the compiler, which is contained in the JDK.

    This article illustrates how to update the Java Development Kit (JDK) version on Windows and Mac.

    Overview

    Xamarin.Android uses the Java Development Kit (JDK) to integrate with the Android SDK for building Android apps and running the Android designer. The latest versions of the Android SDK (API 24 and higher) require JDK 8 (1.8). Alternately, you can install the Microsoft Mobile OpenJDK Preview. The Microsoft Mobile OpenJDK will eventually replace JDK 8 for Xamarin.Android development.

    To update to the Microsoft Mobile OpenJDK, see Microsoft Mobile OpenJDK Preview. To update to JDK 8, follow these steps:

    • Visual Studio
    • Visual Studio for Mac
    1. Download JDK 8 (1.8) from the Oracle website:

      What’s new in Java SE Development Kit (JDK) 18.0.1.1:

      • Enable Windows Alternate Data Streams by default:
      • The Windows implementation of java.io.File has been changed so that strict validity checks are not performed by default on file paths. This includes allowing colons (‘:’) in the path other than only immediately after a single drive letter. It also allows paths that represent NTFS Alternate Data Streams (ADS), such as “filename:streamname”. This restores the default behavior of java.io.File to what it was prior to the April 2022 CPU in which strict validity checks were not performed by default on file paths on Windows. To re-enable strict path checking in java.io.File, the system property jdk.io.File.enableADS should be set to false (case ignored). This might be preferable, for example, if Windows special device paths such as NUL: are not used.

      The Java programming language is, according to the TIOBE programming community index, one of the top choices of software developers, battling for supremacy with the C and C-based languages. Its features are utilized on most of the electronic equipment worldwide, from PCs, mobile terminals or media players to more sophisticated medical devices.

      The Java platform provides one environment to develop software for multiple operating systems such as Microsoft Windows, Mac OS X or Linux distributions. While theJava Runtime Environment (JRE) allows you to execute Java applications, components and applets, the Java Development Kit (JDK) delivers a comprehensive set of tools for programmers to build, run, debug and even document the Java code.

      You are also given access to the Java Virtual Machine (JVM) component of JRE alongside class libraries and support files in order to implement your applications. JDK comes packing demonstrative source codes and particular APIs using Java Foundation Classes including Swing as well as the Java Platform Debugger Architecture. It also sports learning material for Java programming language beginners in the form of various Java core API source files.

      Being the most commonly used Java Software Development Kit (SDK), JDK’s firsthand components comprise the loader for Java application (simply called `java`) – the interpreter of class files created by the compiler (javac), the compiler itself that takes the source code from its raw form to Java bytecode and the `appletviewer` for executing and debugging java applets.

      In addition to these tools, the JDK also brings the annotation-processing tool, the `extcheck` for JAR-file conflict detection, the `idlj` IDL to Java compiler, the `javadoc` documentation generator that utilizes source code comments or the `jar` archiver that sums up the related class libraries within a single JAR file. Other tools include a disassembler, a launcher, a debugger, a Java command-line script shell or a policy creation and management utility.

      Bottomline is that Java Development Kit ensembles a powerful set of tools and everything that comes to aid programmers no matter their knowledge-level in fulfilling their Java applications. Nevertheless, JDK is the bread and butter of any Java developer out there.

      Java is a computer programming language that is concurrent, class-based and object-oriented. It was originally developed by James Gosling at Sun Microsystems. Java applications are compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture.

      Java is currently owned by the Oracle Corporation which acquired Sun Microsystems in 2010. Following tutorial will show you how to setup and configure Java 10 on Windows so you can develop and run Java code.

      Check following posts if you are looking to download and install JDK 1.5, JDK 1.6, JDK 1.7, JDK 1.8 or JDK 1.9.

      Java can be obtained from the Oracle Java download page. There are a number of different Java packages available, for this tutorial we will be installing Java Standard Edition (SE) on Windows.

      In order to be able to compile Java code, we need the Java Development Kit (JDK) package that comes with a Java compiler. The JDK package also comes with a Java runtime environment (JRE) that is needed to run compiled Java code.

      As we are installing the latest Java version, you can find it at the top of the Oracle Java download page. Click on the Download button right below JDK .

      Accept the License Agreement and pick the correct download for your operating system. In this example, we will use the Windows 64 bit version.

      How to install the java software development kit

      Sign in using your Oracle account (or create a new one) and the download should start. Once the download is complete, locate the jdk-10.0.1_windows-x64_bin.exe file and double-click to run the installer.

      How to install the java software development kit

      Click Next and on the following screen optionally change the installation location by clicking on the Change. button. In this example the default install location of ‘C:\Program Files\Java\jdk-10.0.1\’ was kept. From now on we will refer to this directory as: [java_install_dir] .

      How to install the java software development kit

      We will not install the public JRE as the JDK Development tools include a private JRE that can run developed code. Select the Public JRE dropdown and click on This feature will not be available. as shown below.

      How to install the java software development kit

      Click Next and then Close to finish installing Java.

      How to install the java software development kit

      In order for Java applications to be able to run we need to setup a ‘JAVA_HOME’ environment variable that will point to the Java installation directory. In addition, if we want to run Java commands from a command prompt we need to setup the ‘PATH’ environment variable to contain the Java bin directory.

      When using Windows the above parameters can be configured on the Environment Variables panel. Click on the Windows Start button and enter “ env ” without quotes as shown below.

      How to install the java software development kit

      Environment variables can be set at account level or at system level. For this example click on Edit environment variables for your account and following panel should appear.

      How to install the java software development kit

      Click on the New button and enter “ JAVA_HOME ” as variable name and the [java_install_dir] as variable value. In this tutorial the installation directory is ‘C:\Program Files\Java\jdk-10.0.1’ . Click OK to to save.

      How to install the java software development kit

      Click on the New button and enter “ PATH ” as variable name and “ %JAVA_HOME%\bin ” as variable value. Click OK to save.

      Note that in case a ‘PATH’ variable is already present you can add “ ;%JAVA_HOME%\bin ” at the end of the variable value.

      How to install the java software development kit

      The result should be as shown below. Click OK to close the environment variables panel.

      How to install the java software development kit

      In order to test the above configuration, open a command prompt by clicking on the Windows Start button and typing “ cmd ” followed by pressing ENTER . A new command prompt should open in which the following command can be entered to verify the installed Java version:

      The result should be as shown below.

      I have installed Java runtime 6 to C:\src\libraries\jre6 .

      I installed Java JDK to C:\src\libraries\javasdk .

      My %PATH% is set to:

      PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\system32 \WindowsPowerShell\v1.0;C:\src\libraries\javasdk\bin;C:\src\libraries\javasdk;C: \src\libraries\javasdk\jdk\bin;C:\src\libraries\javasdk\jdk;C:\src\libraries\jav asdk;

      When I run the Android SDK installer I get the error:

      “Java SE development Kit (JDK) not found”

      I’m at a loss as to what the Android SDK cannot really find.

      Windows 7 32 bit has the same behaviour as Windows XP SP3. Hit BACK and then NEXT again and you’re able to install the Android SDK.

      How to install the java software development kit

      The answer is bang on, but some clarification that might help some not familiar with registry editing (like me).

      1. Run regedit.
      2. Find [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit]
      3. Right click on the key and click export, then save the file to the desktop.
      4. Right click then click edit.
      5. Add Wow6432Node to the path of each key in the file. See above (@Rog_enk) for an example. Save.
      6. Back in regedit, click File->Import and select the file from above. Done.
      7. Try the SDK installer again.

      On Windows 7 x64 the Android SDK Installer is looking for the JDK in the HKLM\SOFTWARE\Wow6432Node\JavaSoft registry branch.

      But in reality the JavaSoft entry was placed in HKLM\SOFTWARE\JavaSoft . I copied all JavaSoft branch to the path search, and then the installer found the JDK.

      Just press back, then next and it will find it. Android SDK installation doesn’t find JDK

      Windows 7 64 bit – same behaviour as windows XP SP3 and Windows 7 32 bit: Just set JAVA_HOME = C:\Program Files\Java\jdk1.6.0_14 or whatever your actual path, start SDK, and after you’ll get error – hit BACK and than NEXT again and you’re able to install the Andriod SDK

      It seems that creating and setting my environment variable, CLASSPATH , to C:\src\libraries\jre6\lib fixed my problem. I downloaded the Android SDK zip file, put it where I wanted it. I was able to proceed from there.

      Description

      Java SE Development Kit 9.0.1 was available to download from the developer’s website when we last checked. We cannot confirm if there is a free download of this software available. The most popular versions of the program are 9.0, 8.0 and 1.8. The program is included in Development Tools.

      The actual developer of the free software is Oracle. We cannot guarantee that the program is safe to download as it will be downloaded from the developer’s website. Before launching the program, check it with any free antivirus software.

      The program is sometimes distributed under different names, such as “Java SE Development Kit1”. Appletviewer.exe, UPDATE.EXE, rmid.exe, jmc.exe or jmap.exe are the common file names to indicate this program’s installer. The latest version of the program is supported on PCs running Windows 2000/XP/Vista/7/8/10, both 32 and 64-bit.

      From the developer:

      Java SE Development Kit is an environment designed for building applications, applets and components using the Java programming language. The program provides you useful tools for developing and testing programs written in the Java programming language and running on the Java platform.

      You may want to check out more software, such as Java SE Development Kit Update 112, Java SE Development Kit Update 121 or Java Servlet Development Kit, which might be similar to Java SE Development Kit.

      It’s a pretty straightforward and easy process, and we’ll show you step-by-step instructions on how to install Java on Ubuntu. These instructions will work for Ubuntu 16.04, 18.04, Ubuntu 20.04, and any other LTS release, or even other Ubuntu-based distros like Xubuntu.

      This should work for any Ubuntu-based distro, even non-LTS versions like 20.10, but they were tested on Ubuntu 18.04 and Ubuntu 20.04. They should work on both servers and desktops.

      In a hurry? Click here and follow the instructions.

      Before we begin installing Java

      Some things you’ll need before we start installing Java:

      • An Ubuntu server. You can get one from Vultr or any other cloud hosting provider
      • A sudo/root user. All commands below are executed by the root user. If you’re using a non-root user then you’ll need to append ‘sudo’ to most commands.
      • An SSH client like MobaXterm (if you use Windows), or SSH enabled (if you use Ubuntu)
      • Make sure you don’t have Java already installed. If you do, remove it, or if you want to use multiple Java versions/installs, then keep it and configure them later.

      So that’s pretty much it.

      There are multiple ways of installing Java

      We’ll order them based on difficulty (easiest first):

      1. Contact us and we’ll install and configure Java for you (any version, any OS)
      2. Installing the latest Java using the default (Ubuntu’s) JDK using apt-get (use this if you don’t know what to choose)
      3. Installing Java 11 or Java 13 using Oracle’s JDK with apt-get
      4. Installing Java manually using Oracle’s JDK (not recommended for beginners)

      How to install Java (the default JDK) on Ubuntu using apt-get

      We’ll start with our instructions on how to install the latest recommended version of Java (JDK) using the Ubuntu package. By installing the JDK (Java Development Kit), you’ll also install the JRE (Java Runtime Environment). This is the OpenJDK package which is an open source implementation of Java.

      Step 1: Update Ubuntu

      The first thing you should always do is update your system. You can do so by running the following commands:

      Step 2: Install the default JDK

      Run the following command:

      And that’s it. Depending on when you’re reading this, the command will install Java 11 or a newer version. You can now move on to step 3 and configure your Java.

      How to install Java 17 using the Oracle JDK

      If you don’t want to use Ubuntu’s default open source JDK, you can use the official Oracle JDK through a 3-rd party repository.

      Step 1: Update Ubuntu

      Again, you should always update your system first before you do anything else. Run the following commands:

      And install the required package if you don’t have it already installed:

      Step 2: Add the Java repository

      The first thing you need to do is add a 3-rd party repository to get the Oracle JDK. We’ll use the one from Linux Uprising, but you can use any other repository:

      And then update your package list again:

      Step 3: Install Java 17

      So to install the JDK 17th (LTS), latest version, run the following command:

      The command is pretty similar for other versions too (if you want to install another version, replace the XX)

      And that’s it. You can now move on to step 4 and configure your Java.

      No longer recommended: How to install Java 8 using the Oracle JDK

      To install Java 8 (which will reach its end of life January 2019!), follow these instructions:

      Step 1: Update Ubuntu

      Again, you should always update your system first before you do anything else. Run the following commands:

      And install the required package if you don’t have it already installed:

      Step 2: Add the Java repository

      The first thing you need to do is add a 3-rd party repository to get the Oracle JDK. We’ll use the one from WebUpd8, but you can use any other repository:

      And then update your package list again:

      Step 3: Install Java

      So to install the JDK 8th, outdated version, run the following command:

      And that’s it. You can now move on to step 4 and configure your Java.

      How to install Java manually using Oracle’s JDK on Ubuntu

      This step is not recommended for beginners. You won’t get updates from Ubuntu’s repositories, you’ll have to manually update your Java each time there’s a new release. If you want to install a custom version of Oracle’s JDK that’s not available via a package, you can follow the steps below.

      Step 1: Update

      As always. Update first:

      Step 2: Download the JDK

      Go to Oracle’s downloads page and select the version you want to download. We’ll use Java’s Standard Edition 17 for the purpose of this tutorial. Replace the version numbers if you’re going to use a different version. Java 17 is only available for 64-bit systems, so if your Ubuntu is 32-bit, you must use a different version.

      Update 2019: Now that you need an Oracle.com account to download the file below, you’ll have to manually download the file and continue the process after the next step. Alternatively, you can just use the Ubuntu repositories.

      Download the .tar.gz file:

      The Java version and this link often change, so please go to the download page yourself and copy the link yourself.

      Create a directory for your Java installation:

      This is where we’ll install Java. You can use a different directory if you want to install it elsewhere like /usr/local

      Step 3: Install Java

      Now extract the .tar.gz (tarball) file to the directory you previously created

      And that’s it. move on to step 4 and configure your Java.

      Setting up Java on Ubuntu

      Now it’s time to configure your Java.

      Check what Java version you’re using

      First, make sure you’ve installed Java on your system and check what version you have:

      The output should be something like:

      So based on this, we’re using version 11.

      Set a default if you have multiple Java installations

      If you have multiple Java installations, you can set a default one by using the following command:

      You can also use this command to check if you have multiple installations.

      You’ll get an output with a list of installed Javas. Press enter to keep the default one without any changes or enter a number to select a different default Java.

      Set the JAVA_HOME variable

      You’ll most likely need to set the JAVA_HOME variable so other applications can find the location of your Java installation. To find the Java installation path, run the previous command again:

      And copy the installation path – second column – under “Path”.

      Next, open the file “/etc/environment” with a text editor

      And add the following line at the end of the file:

      Of course, make sure you update the path with the one you previously copied, example:

      Save the file and then reload it:

      To test if everything’s done right, you can check your JAVA_HOME variable using:

      And the output should be your Java installation path.

      There are multiple ways of setting up the JAVA_HOME variable, and multiple other variables that you may need to set, depending on what you need and what you’re going to use.

      If you need any help or have any questions, leave a comment.

      Used by over 10 million developers and running on 56 billion devices globally, the Java Platform truly moves the world forward, and now even faster with Java 18.

      Oracle JDK 15 is licensed under Oracle Technology Network (OTN) license. You can use it freely for personal and non-commercial use. For commercial use, you need to pay for a license in terms of Java SE subscription program.

      1. Download Oracle JDK 15

      So head over to Oracle’s official Java SE Download page, and choose to download Windows x64 Installer. Then you will get a file named jdk-15_windows-x64_bin.exe downloaded onto your computer.

      After download, I recommend you to verify the integrity of the downloaded file by running the following command:

      certutil –hashfile jdk-15_windows-x64_bin.exe SHA256

      Then compare the outputted SHA256 value with the one published on Oracle’s website here. If two checksums match, you can safely run the setup program.

      2. Install Oracle JDK 15

      How to install the java software development kit

      Java is one of the most well-known programming languages for building different kinds of applications such as Jenkins, Tomcat server, IntelliJ IDEA, and many other system software.

      This tutorial will show you the way to install various versions of Java, Java Runtime Environment (JRE) and Java Development Kit (JDK) on Ubuntu 20.04 LTS machine.

      Install default java

      The simplest way to install Java on your Ubuntu 20.04 is using the default version come along with Ubuntu operating system.

      Firstly, let’s update the software repository by running the following command:

      Next, it’s recommended that you should check whether Java is installed or not? Run the command:

      The following output indicates that Java has not installed on your Ubuntu 20.04:

      How to install the java software development kit

      Now, you can install the default JRE by executing the following command:

      After the installation has completed, let’s verify the Java version:

      If you want to compile and run the Java applications, you need a program called ‘javac’ and it comes with JDK (Java Development Kit). To install default JDK, let’s run the following command:

      You can verify the JDK installation by checking the version of the Java compiler:

      Install OpenJDK 11

      At the time of this writing, Java 11 is the latest LTS version. It is the default development and runtime environment of Java on Ubuntu 20.04.

      To install OpenJDK 11, run the following command:

      Checking the java version:

      Install OpenJDK 8

      In some cases, your applications require the previous version of Java in order to be run. For example, if you want to install Java version 8 on Ubuntu 20.04, run the following command:

      Verifying the java version by typing command ‘java -version’.

      Install Oracle Java 11

      Unlike the OpenJDK, Oracle JDK is not released under License GPL v2 but Oracle Binary Code License Agreement. By default, the Oracle JDK can not be installed via package managers. You have to download the Oracle JDK 11 installer on Oracle website:

      Choose the Linux Compressed Archive, then click Download:

      You will be redirected to the login screen of Oracle website. You have to create an account to download Oracle JDK Installer.

      After the Java installer has been downloaded (jdk-11.0.8_linux-x64_bin.tar.gz), let’s install the ‘add-apt-repository’ command:

      Then, importing the signing key for verifying the software installation on your Ubuntu 20.04:

      Adding the Java repository to the packages sources list and update:

      Creating the local directory for the downloaded Oracle JDK installer:

      Now, you can install the Oracle JDK 11 by running the following command:

      Let’s accept the Oracle Technology Network License Agreement for Oracle Java SE to finish the installation:

      Manage multiple Java installations

      So far, you’ve installed several versions of Java on your Ubuntu 20.04. It’s necessary to configure the default Java version used by the operating system. You can do it by running the command:

      Enter your desired choice then press Enter to choose your preferred Java version.

      In order to configure the default Java compiler version (javac), let’s run:

      Set Environment Variable

      In many cases, when the developers built their Java programs, they have to specify the $JAVA_HOME environment variable.

      In order to set the $JAVA_HOME variable, you need to locate the installation directory of Java by using the ‘update-alternatives’ command.

      For example, the Oracle Java is located in ‘/usr/lib/jvm/java-11-oracle/bin/’.

      Add the path to ‘/etc/environment’ file

      Reload the environment file for applying the change:

      Verify the $JAVA_HOME environment:

      Conclusion

      In this tutorial, we learned how to install and configure Java on Ubuntu 20.04. Java is crucial for a number of software applications.

      Thanks for reading and please leave your suggestion in the below comment section.

      Not every DevOps or software quality tool requires the Java Runtime Environment in order to function. Source code management tools, like Git and Subversion, fall into the non-Java category, as do popular configuration management tools, like Chef and Puppet. But there are a large number of Java build tools and Java testing tools that do require a Java Development Kit installation, with a few of the most noteworthy being Groovy, Gradle and Jenkins CI. Each of these tools requires a JDK download and subsequent JRE installation in order for any of their features to function.

      In this Java video tutorial, we’ll walk through how to choose the correct JDK download and perform the JRE installation. This video also shows you how to configure a Java 10 installation by setting up the important JAVA_HOME system variable and adding the JDK’s bin directory to the Windows PATH variable. And while this tutorial demonstrates a Windows-based JDK download and JRE installation, the steps are essentially the same, regardless of whether you are a doing a JDK download on macOS or performing the JRE installation on a Linux machine.

      The JDK download and JRE installation are fairly straightforward processes. However, there are a couple of points that are worth clarifying before watching the installation tutorial.

      Download the Java 10 JDK

      First, the JDK download includes the JRE, so the JRE is not a separate download. The JRE is packaged along with the JDK. Along with the JRE, the JDK download also includes a variety of other development tools, such as a Java compiler and a Java package and archive tool. It is possible to download just the JRE from Oracle, but this download doesn’t include the extra development tools that products like Jenkins or Gradle need. So, when visiting Oracle’s software site, make sure the JDK download is selected and not just the plain old JRE.

      Include the JDK to the PATH

      Secondly, it is important to point the OS’ PATH variable to the bin directory of the JDK installation. The bin directory is where the compilation and archiving tools are found. By placing the bin directory of the JDK installation on the OS’ global PATH variable, a command-line program can easily invoke the Java tools and utilities by name rather than having to include the name of the directory in which they were installed. In this Java video tutorial, the Windows PATH variable will be configured to include the following directory: C:\_jdk10\bin.

      Configure JAVA_HOME on Windows

      Thirdly, whenever you perform a JDK download and install, it is important to set up a new environment variable named JAVA_HOME and point it to the directory in which the JDK was installed. Tools like Gradle, Tomcat or Jenkins require that Java look for this JAVA_HOME environment variable when they start, so it is important to configure it correctly. In this Java tutorial, the JDK will be installed into a directory named C:\_jdk10, which is the value that will be given to the JAVA_HOME variable.

      Not to worry, the accompanying Java video tutorial will walk you through each of these configurations. Be aware of what these steps are and why they are being performed to get the most out of the video.

      Java allows you to play online games and chat with people around the world. Also calculate your mortgage interest, and view images in 3D. These applications, written in the Java programming language and access from your browse, are called “applets”.

      The companies use Java in all major industries. Corporations also use Java applets for intranet applications and other e-business solutions.

      Java offers the rich user interface, performance, versatility, portability, and security. That today’s networked applications require. Whether deployed on phones, embedded devices, game consoles, laptops, or in datacenters.

      Java Key features:

      • Write software on one platform and run it on practically any other platform
      • Create programs to run within a web browser and web services
      • Develop server-side applications for online forums, stores, polls, HTML forms processing, and more
      • Combine Java technology-based applications or services to create highly customized applications or services
      • Write powerful and efficient applications for mobile phones, remote processors, low-cost consumer products. Write apps for practically any device with a digital heartbeat.

      Standard Edition is the premier platform for rapidly developing and deploying secure. Also for portable applications that run on server and desktop systems spanning most operating systems.

      Runtime Environment contains the Java virtual machine, runtime class libraries and Java application launcher. That are necessary to run programs written in the Java programming language.

      Java technology is an object-oriented, platform-independent, multithreaded programming environment. You can depend on a consistent programming environment. Whether developing applications for consumers or mission-critical deployments.

      • Enables you to efficiently deploy exciting new applications and services.

      • Runs across more than seven billion devices. Tha latter are mobile, desktop, television, and countless embedded devices.

      Java is everywhere – and for good reason. It is the global standard for developing and delivering mobile applications, games, Web-based content, and enterprise software.

      Java technology was created as a computer programming tool in a small, secret effort called “the Green Project” at Sun Microsystems in 1991. As it turns out, the Internet was ready for Java technology. And just in time for its initial public introduction in 1995, the team was able to announce that the Netscape Navigator Internet browser would incorporate Java technology.

      How to install the java software development kit

      With Red Hat Enterprise Linux (RHEL) 8, two major versions of Java will be supported: Java 8 and Java 11. In this article, I’ll refer to Java 8 as JDK (Java Development Kit) 8 since we are focusing on the development aspect of using Java. JDK 8 and JDK 11 refer to Red Hat builds of OpenJDK 8 and OpenJDK 11 respectively. Through this article, you’ll learn how to install and run simple Java applications on RHEL 8, how to switch between two parallel installed major JDK versions via alternatives and how to select one of the two JDKs on a per-application basis.

      TL; DR

      To install JDK 8, use: (If you didn’t select Make this user administrator during install see this article to enable sudo on RHEL)

      Then run Java “Hello World” as follows:

      To instal JDK 11, use:

      Then run Java “Hello World” as follows:

      Yes, with JDK 11 you can directly run Java source files. The compilation step is handled for you.

      Watch the Video

      If you prefer to watch a short 4 minute demo video, here it is:

      The Longer Version.

      Let’s consider we have a freshly commissioned Red Hat Enterprise Linux 8 machine and we’d like to use it for running Java applications.

      Finding available Java packages

      In order to figure out which RPM packages to install, we can ask the packaging system which ones provide the java binary:

      This command tells us that packages java-1.8.0-openjdk-headless and java-11-openjdk-headless both provide the java binary. For the purpose of this article, we’re interested in the development kits, so we’ll install the -devel sub-packages instead. The -devel packages will pull in -headless packages as a dependency. If you already know that RHEL packages are OpenJDK builds, yum list available might be useful too:

      For the purpose of this article, we are going to install JDK 8 and JDK 11 in parallel, and also install maven:

      Switching Java Versions

      In the previous step, we installed JDK 8 and JDK 11 in parallel. At this point in time, JDK 8 is the main JDK on RHEL 8. That’s why you get this output when running java -version on a fresh RHEL 8 install:

      There are two ways to select the Java version you want:

      1. Switch java and javac binaries system wide via alternatives. This approach requires root privileges.
      2. Select the JDK on a per-application basis by setting JAVA_HOME

      Selecting Java Versions with Alternatives

      java and javac binaries on RHEL 8 are managed by the alternatives system. This means a system administrator can switch the system java (or javac ) to be something other than the default, JDK 8. The alternatives system uses priorities in order to determine which JDK should be available via /usr/bin/java . JDK 8 has been given a higher priority on RHEL-8 than JDK 11. But we are getting ahead of ourselves. First, lets see which binaries are managed by alternatives:

      We see that java and javac are managed by alternatives. Next, we are going to switch to JDK 11, using the alternatives –config command:

      This will switch the system java binary to JDK 11. We do the same for javac since java and javac are independently managed. There is no need to switch anything else as every other JDK binary will switch either with the java or the javac binary:

      Switching alternatives non-interactively

      Here is an approach to switch to JDK 11, via alternatives, using non-interactive means, which comes in handy if you need to script it:

      Similarly, switching to JDK 8 via alternatives by non-interactive means:

      A similar approach can be followed for javac .

      Selecting Java Versions by Setting JAVA_HOME

      Many applications support using the JAVA_HOME environment variable, as a way to specify which JDK should be used to run the application. The examples below demonstrate this usage when running maven. This approach is handy if you don’t have root privileges, but both JDKs are already installed on your system.

      Selecting JDK 8:

      Selecting JDK 11:

      This feature also comes in handy if you have multiple minor JDK versions installed as Leo Ufimtsev described in his article for RHEL 7.

      • A user account with sudo privileges
      • Access to the command-line/terminal window
      • The yum package manager, included by default

      Java Versions

      Currently, there are four Java platforms available:

      1. Java Standard Edition (Java SE)
      2. Java Micro Editions (Java ME)
      3. Java Enterprise Edition (Java EE)
      4. JavaFX

      In this document, we look at different packages within the Java SE.

      There are two (2), open-source Java packages, Java Development Kit (Open JDK) and Java Runtime Environment (Open JRE). You use JRE for running Java-based applications, while JDK is for developing and programming with Java.

      Also available is Java Oracle, another SE implementation, which has additional commercial features. You can find the official Oracle JDK through a third-party repository or on the official Oracle webpage. However, bear in mind its license only allows non-commercial use of the software.

      Install Java On CentOS

      You can install one or several Java packages on your machine. You can also decide which version you want on your system by installing a specific version number. The current default, Long-Term-Support (LTS) version is Java 11.

      Install OpenJDK 11

      1. Update the package repository to ensure you download the latest software:

      2. Then, install the Java Development Kit with the following command:

      The output displays the downloaded and installed JDK, as in the image below:

      How to install the java software development kit

      Install OpenJRE 11

      Java Runtime Environment 11 (Open JRE 11) is a subset of OpenJDK. Therefore, both packages are included in the command:

      Install Oracle Java 11

      1. The official Oracle JDK is not available for download from the local repository. You have to download the .rpm package from the Java SE Downloads page.

      2. The latest release is Java SE 12. However, Oracle Java 11 is LTS, meaning it is the latest stable version.

      Locate Java SE 11.0.3 (LTS) on the webpage and click on DOWNLOAD.

      Install Specific Version of Java

      You can also install any of the other versions of Java by changing the version number in the command.

      Install JDK 8

      You may decide to use Open JDK 8, instead of the default OpenJDK 11.

      To do so, type in the following command in the terminal:

      Install JRE 8

      As a subset of Open JDK 8, you can install Open JRE 8 by typing in the command:

      Install Oracle Java 12

      As previously mentioned, you have to download Oracle Java from its official page.

      To install the newest version, simply download the appropriate package from their webpage and continue with the installation.

      How to Set Default Java Version

      Since you can have multiple versions of Java installed on your system, you can decide which one is the default one. To do so;

      Run a command that shows all the installed versions on your computer:

      How to install the java software development kit

      The image above shows that there are two alternatives to this system. These choices are represented by numbers 1 (Java 11) and 2 (Java 8).

      To change the default version, type the associated number (in this case, 1 or 2) and press Enter.

      How to Set JAVA_HOME Environment Variable

      Setting the JAVA_HOME environment variable helps other applications compiled in this programming language to access Java’s installation path easily.

      1. First, locate where Java is installed:

      How to install the java software development kit

      In the output, you can find the path for each Java package installed on the system.

      • /usr/lib/jvm/java-11-openjdk-11.0.3.7-0.el7_6.x86_64/bin/java (where OpenJDK 11 is located)
      • /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java (where OpenJDK 8 is located)

      2. Once you see all the paths, copy the one of your preferred Java version.

      3. Then, open the .bash_profile with any text editor. In this example, we use vim:

      4. At the bottom of the file, add a line which specifies the location of JAVA_HOME in the following manner:

      For example, if we copy the installation path for Java 11 in the previous step, the added line in the text editor will be:

      How to Uninstall Java on CentOS

      In case you need to remove any of the Java packages installed, use the yum remove command.

      For example, to remove Open JDK 8 use the following command:

      Confirm the process by pressing y (yes), and it will uninstall the package from CentOS, as in the image below:

      In this short tutorial, we’re going to take a close look at how to install Java on Windows 10.

      We’ll first start with a little insight into how to download Java. Then, we’ll explain how to install it on Windows 10. Then, we’re going to see how to properly set JAVA_HOME environment variable.

      Lastly, we’ll highlight different ways to check Java and JDK versions on Windows 10.

      So, let’s get started

      Download Java for Windows 10

      In this section, we’re going to cover in-depth all the steps required to download Java for Windows 10.

      As a matter of fact, downloading Java is a piece of cake. It’s just a matter of a few clicks and simple one-time steps.

      First, we need to visit the official oracle download page and choose the right release for the Java SE Platform. At this point in time, the latest version is Java 18.

      Secondarily, we need to click on the Windows tab.

      Bear in mind that Oracle has dropped the support for 32 bit systems. As a result, we can use Java SE only in 64 bit machines.

      Oracle offers three options to install Java on Windows. We can use a compressed archive file, a x64 Installer or a x64 MSI Installer.

      For instance, let’s choose the x64 Installer option:

      Before Java 17, we had to accept the Oracle Technology Network License Agreement to proceed to the next step, which is not the case for Java 18

      Lastly, a simple click on the download link will do the job. Easy, right?

      Install Java on Windows 10

      Now that we downloaded Java for Windows 10, let’s see how to install it.

      Basically, the process of installing Java on Windows 10 is pretty easy and simple.

      In general, we don’t need to change anything during the installation, we can go with the default settings and follow the suggested instructions.

      Firstly, we need to double click on the downloaded installer file to start the installation process:

      Secondarily, we click Next to continue:

      Note that, “C:\Program Files\Java\” is the default Java installation folder! However, we can always change it if we want that.

      Then, we keep hitting Next until the installation is complete:

      Finally, we close the installer wizard to complete the installation.

      Set Java Path in Windows 10

      Now that we have installed Java with success, it’s time to proceed to the next step.

      In this short chapter, we’re going to dive deep into how to set JAVA_HOME environment variable on Windows 10.

      Add JAVA_HOME

      The basic idea behind setting the Java Path is to make all the Java commands like java and javac accessible from everywhere. That way, we can run Java programs from anywhere.

      Please note that, JAVA_HOME should point to the JDK not the JRE.

      First, let’s open the Advanced System Settings. To do that, we just need to press Windows key + Pause Key.

      Alternatively, we can type View advanced system settings in the search box.

      Once the System Properties window is opened, we click on Environment Variables:

      Secondarily, we click on the New button to create a new environment variable with JAVA_HOME as name and the path to the JDK directory as value:

      As we can see, the JAVA_HOME environment variable points to the JDK folder which C:\Program Files\Java\jdk-18.0.1.1 is in our case.

      Append JAVA_HOME to PATH

      Next, we need to update the PATH variable by adding a new entry for %JAVA_HOME\bin%:

      Finally, we can click OK to save and apply the changes.

      That’s all we can say about downloading and installing java on windows 10. Now, we’re ready to write our first Java program.

      Check Java Version on Windows 10

      There are multiple ways that we can use to check Java version on Windows 10. The most obvious and basic way is to use the terminal.

      Firstly, press Win+R and type cmd to open the Command Prompt. After that, type java -version and press Enter:

      The output means that Java is properly installed on our operating system.

      Alternatively, we can type “Java” in the search box and click on “About Java”:

      Please bear in mind that multiple versions of JDK can be installed on the same on Windows 10 machine. So, it’s important to make sure the JAVA_HOME environment variable points to the right JDK release.

      Let’s open a new command prompt and type:

      As show above, the environment variable JAVA_HOME points to the directory of the lastest JDK version.

      We can also use javac -version to verify the version of the installed JDK:

      Another important thing to note here is that the JDK version can be different from the JRE version on the same machine.

      Please keep in mind that we need always to check for new Java updates and install them to keep our machines up-to-date with the latest releases.

      Write First Java Program

      Now that we installed Java, let’s see how to create our first Java program.

      To do so, let’s open an IDE or a text editor of your choice, for example, Notepad++, and create a new file (ctrl+n).

      Next, we need to append the following code in our newely created file:

      Now, let’s save our file anywhere we want under the name: HelloTest.java

      In order to execute our Java program, we need to compile it first. So, let’s open a terminal and type:

      As we can see, javac creates a new file with the name HelloTest.class. This means that the compilation phase is done with success.

      Lastly, let’s run our Java program using the java command:

      Please bear in mind that we don’t need to specify the extension when executing a Java file.

      Conclusion

      In this article, we’ve explained how to tackle the challenge of downloading and installing Java on Windows 10. Then, we’ve seen how to add JAVA_HOME and append %JAVA_HOME\bin% to the Path.

      Lastly, we have showcased how to verify and check the installed Java version.
