Java : Class inheriting self

Question

I know this is pointless: I just find it funny and I want to inquire more about the mechanics of what happens when you create a class that inherits itself, resulting in a stack

Answer 1

The example you posted could get problematic if we change it a bit more:

public class Outside {

    public class Inside extends Outside {

            public Inside(int val) {
        }

    }

    private Inside i;

    public Outside() {
        i = new Inside();
    }
}

But this is not really related to the fact that Inside is an inner class of Outside, it could have happened with separate top-level-classes identically.
