Able to define methods for subclasses?

Question

I was wondering if it was possible to define methods specific to subclasses.
For example, I have an abstract class as follows:
public abstract class Card {
}I also have two subclasses as follows:
public class StandardCard{
public class NumberCard{
}I wanted to create a compareTo() method that every subclass of card must implement, but I don't want to allow a subclass to be compared with a different subclass such as:
new StandardCard(King, Diamonds).compareTo(new NumberCard(1));So, is there a way to declare something as follows:
public abstract class Card {
public abstract int compareTo( /*same type as the dynamic type of the object*/ card);
}

Answer 1

Is there a way to check for the generic type of an object as well?
For example, I also wanted to assign values of card, but depending on the game a value might change. So I created an interface as follows:
public interface CardValueAssigner<T extends Card> {
     public int valueOf(T card);
}In the Card class, I have as follows:
public abstract class Card {
     public int getValue(CardValueAssigner<Card> assigner) {
          return assigner.valueOf(this);
}Is there a way to check the type of card that is within the ' < > ' of CardValueAssigner, or will I just have to create a method in every subclass.
