Why this code snippet gives error :

1. class Outer {
2. class Inner { }
3. }
4.
5. public class InheritInner extends Outer.Inner {
6. InheritInner () { }
7.
8. public static void main(String [ ] args) {
9. Outer o = new Outer( ) ;
10. InheritInner ii = new InheritInner( ) ;
11. }


Thanks in Advance

The issue is that the InheritInner constructor was not able to call the superclass's constructor, since it could not find an instance of outer class to associate to.

Making the inner class static is also an alternative solution.
