Such problems are not the first time, I don’t remember how I managed to solve it, it seems that I created a new project. Krc is a class, there is a method main() and there is System.out.println("Hello"); When calling Maine, he throws out a compilation error and Error:java: error: release version 5 not supported What could be the problem and how to solve it?
Problem method:
public static void main(String[] args) { System.out.println("Hello"); }
