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

Just have a getter method in the InnerBase?

class Outer {
  int some_member;

  abstract class InnerBase {
    abstract void method();
    protected int getSome_Member() // This is possible, because Abstract classes can have non-abstract methods.
    {
       return some_member;
    }
  }
}

class OuterExtendsInner extends Outer.InnerBase {
  OuterExtendsInner(Outer o) { o.super(); }
  void method() {
       // you can access "some_member" now
      int myNumber = getSome_Member();

  }
}
