difference method java using enum types

Is it possible to calculate the difference between the values of 2 enum types using a static method? Where the enums represent a deck. (i.e. Two(2) of Spades, Queen(10) of Hearts = 8).

public enum Rank {TWO, THREE, FOUR, FIVE, SIX,SEVEN, EIGHT, NINE, TEN, 
                    JACK, QUEEN, KING, ACE}
public enum Suit {CLUBS, DIAMONDS, HEARTS, SPADES}

I want the method to return the difference in ranks between two cards…
Not sure how to approach/efficiently implement this. Thanks

Answer 1

 public static int diff(Rank first, Rank second){
    return Math.abs(first.ordinal() - second.ordinal() + someDefaultValue);
 }
