TRY IT OUT: Dealing Cards
You can use a
Stack<>
object along with another useful method from the
Collections
class to simulate
dealing cards from a card deck. You need a way of representing a card's suit and face value or rank. An
enum
type works well because it has a fixed set of constant values. Here's how you can define the suits:
public enum Suit {
CLUBS, DIAMONDS, HEARTS, SPADES
}
Directory "TryDeal"
The sequence in which the suits are defined here determines their sort order, so
CLUBS
is the lowest and
SPADES
is the highest. Save this source file as
Suit.java
in a new directory for the files for this example.
You can define the possible card face values just as easily:
public enum Rank {
TWO, THREE, FOUR, FIVE, SIX, SEVEN,
EIGHT, NINE, TEN, JACK, QUEEN, KING, ACE
}
Directory "TryDeal"
TWO
is the lowest card face value, and
ACE
is the highest. You can save this as
Rank.java
. You're now
ready to develop the class that represents cards. Here's an initial outline:
public class Card {
public Card(Rank rank, Suit suit) {
this.rank = rank;
this.suit = suit;
}
private Suit suit;
private Rank rank;
}
Directory "TryDeal"
