Access child methods from parent class

[bmL]

Let's say I have for example:

abstract class A {
  
  public A() {
    B b = newB();
    b.test();
  }
  abstract class B {
      void test() {

       }
  }
}
Class B extends A {
  class B extends A.B {
     void test() {
        // i want to access this from parent class A
     }
  }
}
A = new A;...

Is it possible to access child methods from parent class?

EDIT: sorry not method but child class so:

abstract class A {
  
  public A() {
    B b = newB();
  }
  abstract class B {

  }
}
Class B extends A {
  class B extends A.B {
     void A.B() {
        // i want to access this from parent class A
     }
  }
}
A = new A;...

when i run this the extended part is not executed i get instance of parent inner class

Nope; and in your example you can't even create an A because class A is abstract. Why do you want such artificial class hierarchies? Is it an assignment?

I want one abstract class which implements most of functionality so specialized classes need only to implement specialized things. Right now im doing something like this:

abstract Class A {

   addNotify() {
      add(getB());
   }
   abstract B getB();
   abstract Class B {

   }
}
abstract class C extends A {
   
   B getB() {
      return new B();
   }
   class B extends A.B {

   }
}

and it does just fine. But i would like to get rid of the getB method and keep it functioning so I dont have to reimplement the A.addNotify just to call add(new B()); in every specialized class.
