java how to get superclass reference in subclass

I have 3 classes:

class Superclass...

public class Generic{
     public Generic(Superclass s){...}
}

And a subclass extending Superclass

class SubClass extends Superclass{
      public void methodM(){
           Generic g = new Generic(???);
           ...
      }
}

In methodM I use the constructor Generic and I want to pass a reference to the Superclass instance extended by Subclass. So I don't want to do something like new Generic(new Superclass), rather something like: new Generic(super.IdontKnowWhat)

thank you

Solution

  • The reference to the current object is implicitly a reference to a superclass as well (as it extends it).

    So you should be able to do

     Generic g = new Generic(this);
