How to fix "class file versions up to 52.0" error in VS Code?

Hey! So, this issue typically arises because this version of the java runtime only recognizes class file versions up to 52.0. Essentially, it’s a mismatch between your Java runtime (JRE) and the version your class was compiled with. Class file version 52.0 corresponds to Java 8, and version 53.0 means it was compiled with Java 9 or later.

To check which version you’re working with, open up a terminal and run:

java -version

If it shows Java 8 or lower, you’ll need to update your JDK to a version that matches your compiled class file. Here’s how to do that:

  1. Install the latest JDK from Adoptium or Oracle.
  2. Open settings.json in VS Code and set the path to the JDK:
"java.home": "C:\\Path\\To\\Your\\JDK"

Restart VS Code, and you should be good to go!"
