Utilizing the Java Development Kit (JDK) within Windows Subsystem for Linux 2 (WSL2) offers developers a powerful environment for Java development on Windows 10. However, proper setup and configuration are crucial for a seamless experience. In this blog post, we will explore the recommended approach for using JDK on WSL2 in Windows 10. By following these steps, developers can harness the full potential of Java development while leveraging the benefits of WSL2.

Step 1: Installing WSL2 and Linux Distribution:

To begin, ensure that WSL2 is installed and enabled on your Windows 10 system. Follow the official Microsoft documentation to install WSL2 and select your preferred Linux distribution, such as Ubuntu or Debian. Once installed, launch the Linux distribution and complete the initial setup process.

After setting up the Linux distribution within WSL2, the next step is to install the OpenJDK, which is an open-source implementation of the Java Development Kit. In the Linux terminal, execute the following commands to update the package lists and install OpenJDK:

These commands update the package lists and install OpenJDK 11, which is a widely used and stable version. You can also install a different version by specifying it in the command.

Step 3: Configuring Java Environment Variables:

To ensure proper integration and functionality, it is essential to configure the Java environment variables on WSL2. Open the .bashrc file using a text editor:

Add the following lines at the end of the file:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

These lines set the JAVA_HOME variable to the correct JDK path and add the JDK's bin directory to the PATH variable. Save the file and exit the text editor.

To ensure that the JDK is properly installed and configured, open a new terminal window or run the following command to reload the .bashrc file:

Then, verify the Java installation by running the following command:

If the installation was successful, you should see the version information for the installed JDK.

By following these steps, developers can seamlessly utilize the Java Development Kit (JDK) within Windows Subsystem for Linux 2 (WSL2) on Windows 10. Proper installation and configuration of WSL2, OpenJDK, and Java environment variables ensure a smooth and efficient Java development experience. With the power of WSL2 and the versatility of the JDK, developers can unleash their creativity and build robust Java applications on the Windows 10 platform.

The blog provides a step-by-step guide on properly installing and configuring the Java Development Kit (JDK) on Windows Subsystem for Linux 2 (WSL2) in Windows 10.
