Java generics - overriding an abstract method and having return type of the subclass

Question

I am trying to create a set up where a set of subclasses override a superclass. This superclass contains an abstract method - the return type of which would ideally be that of t

Answer 1

This will work:

public abstract class SuperClass{
  public abstract SuperClass getSelf();
}

public class SubClass extends SuperClass{
  @Override
  public SubClass getSelf(){
    return this;
  }
}

Notice I've added extends SuperClass to your SubClass definition. The return type of getSelf is referred to as a covariant return type.
