'How to set Default Java version on windows 10?

I had installed java v 1.8 on Windows 10 for years. JAVA_HOME and Path variables were updated. Then I installed Java 18 today. Did update JAVA_HOME and Path variables according to it.

When I execute java -version command it returns the correct version (v18).

Next, I installed java v11 and updated JAVA_HOME and Path variables for v11. but when I execute java -version it returned v18 as result.

Then I uninstalled v18 from the control panel and executed the same command. Then I returned the correct value. v11

  1. Why did java -version return latest version (v18) even I have updated JAVA_HOME and Path variables for v11 ?

  2. Where is this information saved on PC?

Try running

where Java

Make sure that this returns the path to your Java version you want. Should return something like:

C:\Program Files\Java\jdk-11.0.10+9\bin\java.exe

If not then the environment variables were not set correctly. Make sure that your JAVA_HOME is pointing to the instillation folder, and the path to the \bin folder.

Hope this helps!
