How to Change Java Version in Windows 10: A Simple Guide

Changing the Java Version in Windows 10

Changing the Java version in Windows 10 might sound complex, but it’s actually a straightforward process. You’ll just need to adjust some environment variables and ensure your system recognizes the new version. This quick guide will walk you through the steps needed to switch between different Java versions, ensuring your programs run smoothly with the desired version.

How to Change Java Version in Windows 10

Changing the Java version in Windows 10 involves updating the system’s environment variables. By following these steps, you’ll ensure your computer uses the correct Java version for your needs.

Step 1: Check Installed Java Versions

First, open Command Prompt and type java -version to see the current Java version.

This command quickly shows which Java version is currently in use. It’s helpful to know this before making any changes, so you can confirm the switch later.

Step 2: Open Environment Variables

Next, right-click on ‘This PC’ and select ‘Properties’. Click on ‘Advanced system settings’ and then ‘Environment Variables’.

Environment variables control how applications function. Here, you’ll adjust the settings to point to your preferred Java version.

Step 3: Update JAVA_HOME

Find the ‘JAVA_HOME’ variable and click ‘Edit’. Change the path to point to the folder of your desired Java version.

This step directs your system to look at the correct Java installation folder. Make sure you choose the right path, typically located in ‘C:Program FilesJava’.

Step 4: Modify Path Variable

In the ‘Path’ variable, add the bin directory of your chosen Java version to the list.

The Path variable tells your system where to find executable files. Adding the new Java path here ensures the system can execute Java commands.

Step 5: Verify the Change

Reopen Command Prompt and type java -version to confirm the version has changed.

This final step ensures everything is set up correctly. If the version displayed matches your desired version, congratulations—you’re all set!

After completing these steps, your computer will use the specified Java version for all Java-related tasks. This ensures compatibility with certain applications or programming needs.
