'Visual studio code not showing output, java programming

I'm learning to code Java... I just installed the Java runtime environment and Visual Studio Code, and wrote this:

public class IterationDemo

{
    public static void main(String[] args)
    {
        System.out.println('x');
    }
}

However, I don't see any output, both under output or terminal. Only kind of a rectangle (▯) under terminal. I've tried to find a solution googling, stack and so on but no answer yet... what can I do? Thanks!

OK; got solved on its own - I ended up clearing the cache and then the output came :) Thanks myself!
