How to set up PATH variable in system environment variables

To set up PATH variable in system environment variables, follow these steps:

  1. In the Environment Variables window, under System variables, select Path and click on Edit….
  2. In the Edit environment variable window, click on New.
  3. Type %JAVA_HOME%\bin and press Enter. This will append the location of Java executable files to the PATH variable.
  4. Click OK to close all windows.

Verifying JDK 11 Installation

To verify that JDK 11 is installed correctly on your Windows 10 system, you can check the Java version from a command prompt and test a simple Java program with JDK 11.

How to open a command prompt and check the Java version

To open a command prompt and check the Java version, follow these steps:

  1. Type cmd in the search box on the taskbar and press Enter.
  2. In the command prompt window, type java -version and press Enter.
  3. You should see something like
    java version "11.0.13" 2021-10-19 LTS Java(TM) SE Runtime Environment 18.9 (build 11.0.13+8-LTS-272) Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.13+8-LTS-272, mixed mode) 

    This means that JDK 11 is installed and working properly on your system.

    FAQs

    What is the difference between Oracle JDK and OpenJDK?

    Oracle JDK and OpenJDK are two distributions of JDK that are based on the same source code but have some differences in terms of licensing, support, and updates. Oracle JDK is licensed under Oracle Binary Code License Agreement, which requires a commercial license for production use after January 2019. OpenJDK is licensed under GNU General Public License, version 2, with the Classpath Exception, which allows free use for any purpose. Oracle JDK provides long-term support (LTS) for major releases every three years, while OpenJDK provides updates for six months after each release. Oracle JDK also includes some additional features that are not available in OpenJDK, such as Java Flight Recorder and Java Mission Control.

    What are some new features in JDK 11?

    JDK 11 contains new features and enhancements in many functional areas, such as modules, HTTP client, local variable syntax, lambda expressions, string methods, garbage collectors, and more. Some of the notable features are:

    What are some common issues with JDK 11?

    JDK 11 is a major release that introduces many changes and improvements, but also some potential issues and compatibility problems. Some of the common issues with JDK 11 are:

    • Deprecated and removed features: Some features that were deprecated in previous versions of Java have been removed or disabled in JDK 11, such as Applets, Java Web Start, JavaFX, Nashorn JavaScript engine, CORBA modules, and more. If you have applications that rely on these features, you may need to migrate them to alternative solutions or use older versions of JDK.
    • Changed default behavior: Some features that were optional or experimental in previous versions of Java have become default or stable in JDK 11, such as Unicode support, G1 garbage collector, TLS 1.3 protocol, Flight Recorder and Mission Control tools, and more. If you have applications that depend on the previous behavior of these features, you may need to adjust them accordingly or use flags to disable them.
    • Module system: JDK 11 fully supports the module system introduced in Java 9, which allows modularization and encapsulation of Java code. However, this also means that some packages and classes that were accessible by default in previous versions of Java are now hidden or restricted by modules. If you have applications that use reflection or access internal APIs, you may need to use command-line options or configuration files to enable them. For more information on the module system, you can refer to The State of the Module System or Understanding Java 9 Modules.

    How to update JDK 11 to the latest version?

    To update JDK 11 to the latest version, you can follow the same steps as installing JDK 11, except that you need to download the latest version of JDK 11 from the source website and run the installer over the existing installation. The installer will detect the previous version of JDK 11 and update it accordingly. You do not need to change the environment variables or uninstall the previous version of JDK 11.

    How to uninstall JDK 11 from Windows 10?

    To uninstall JDK 11 from Windows 10, you can follow these steps:

    1. Open Control Panel and click on Programs.
    2. Click on Programs and Features and select Java(TM) SE Development Kit 11 or OpenJDK Development Kit 11, depending on which version of JDK 11 you installed.
    3. Click on Uninstall and follow the instructions provided by the uninstaller.
    4. Delete the installation directory of JDK 11 from your local drive, such as C:\Program Files\Java\jdk-11 or C:\Program Files\Java\openjdk-11.
