Inner class problems

[orchid]

This will not compile for me. It looks like it should..????

public class Outer {
    class Inner1 extends Outer {
        public Inner1()
        {
            super();
        }
        
    }
    class Inner2 extends Inner1 {
        public Inner2()
        {
            super();
        }
        
    }
}

This will fix the compilation issue:

class Inner2 extends Inner1 {
    public Inner2()
    {
        Outer.this.super();
     }      
  }

Better if you can simply explain a little with the answer pal. ;)

Reason is, super(); in Inner2 class cannot refer before the Outer class constructor call, because it's the super class. Inner2 class extend Outer there. Hope it's clear.
