How to make an outer class inherited from an inner class?

Question

How can I make something like this work:

class Outer {
  int some_member;

  abstract class InnerBase {
    abstract void method();
  }
}

class OuterExtends         


        

Answer 1

The outer class can extend the inner class iff the inner class is compiled to ".class".

Now, every time you compile the outer class it encounters the "extends innerclass" which is

not yet compiled and the compiler will throw a NoClassDefException or ClassNotFoundException.

Isn't it ? So you will never get that inner class compiled. If you can overcome this problem

then you can also extend the inner class :) .
