What Arne and Robert said.  In this case you want a single class with 
two fields, one for suit and one for face value.  (You could encode both 
the suit and the value in to a single field.  However this sort of space 
saving is usually counter-productive, unless you're absolutely sure it's 
needed.)

public class PlayingCard {
   private final int value; // Ace = 1
   private final Suit suit;

   public static enum Suit { HEARTS, CLUBS, SPADES, DIAMONDS }

   ... ect....

}


You will of course have to make 52 instances of that class.  Do that at 
runtime, don't try to make 52 files.
