Playing with binary numbers

Question

Hi
I am messing around with classes. I have a card class, which has a rank (2 - 14) and suit (0-3). What I am trying to do, is have a variable in the class cardvalue which holds a binary value for each card, for example, the 2 (2) of hearts (0) would be 0010 00 (I will of course drop the space), I would like it formatted with the first four digits representing the rank, a the second two the suit, for simple comparison with other cards later on in the game.
How do I take the card values and concatenate them together?
Many thanks, Ron

Thanks, I have this:
[code
public class Card
     public enum Rank
     Deuce(2),Three(3),Four(4),Five(5),Six(6),Seven(7), Eight(8), Nine(9), Ten(10), Jack(11), Queen(12), King(13), Ace(14);     
          private final Integer facevalue;
     Rank(Integer facevalue)
     this.facevalue = facevalue;
     public Integer facevalue(){ return facevalue; };
     public enum Suit
          Hearts (0), Clubs(1), Diamonds(2), Spades(3);
          private final Integer suitvalue;
          Suit(Integer suitvalue)
               this.suitvalue = suitvalue;
          public Integer suitvalue(){ return suitvalue; };
     private final Rank rank;
     private final Suit suit;
     private Integer binaryvalue;//value of the card as a 6 bit number, first two suit, second four rank value
     private Card(Rank rank, Suit suit)
this.rank = rank;
this.suit = suit;
//binaryvalue = rank.facevalue & suit.suitvalue;
//binaryvalue = Integer(Integer.toBinaryString( rank.facevalue));
     public Rank rank() { return rank; }
public Suit suit() { return suit; }
public Integer binaryvalue(){ return binaryvalue; }
public String toString() { return rank + " of " + suit; }
