Program Specification:

You are to develop a program which emulates a full deck of playing cards. That is 4 suits (Clubs, Spades, Hearts, and Diamonds) and 13 ranks (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King) in each suit. This of course makes for a total of 52 playing cards in the deck.

Mandatory methods:

public static void initDeck(boolean[] deck)

// set the values of deck to indicate that they are all

// present - not dealt yet.

public static boolean emptyDeck(boolean[] deck)

// returns whether or not all the cards in the deck

// have already been dealt.

public static int dealCard(boolean[] deck)

// returns a card (an int in the range 0 to 51) at random

// that has not been dealt since the deck was initialize

// via intDeck. Also notes (in deck) that this card is

// no longer available.

public static void printCard(int card)

// given a card (an int in the range 0 to 51) prints

// an appropriate representation of this card based

// on a 1-1 and onto mapping of the set [0, 51] to

// the cards described above.

Rules and Requirements:

Your main method must end with the following block of code, which can not be modified.

boolean[] myDeck = new boolean[52];

final int cardsPerRow = 8;

int cardsThisRow = 0;

int myCard;

initDeck(myDeck);

System.out.println(" Here is a shuffled deck ... ");

while (!emptyDeck(myDeck))

{

myCard = dealCard(myDeck);

++cardsThisRow;

if (cardsThisRow <= cardsPerRow)

{

printCard(myCard);

System.out.print(" ");

}

else

{

System.out.println("");

cardsThisRow = 1;

printCard(myCard);

System.out.print(" ");

}

}

System.out .println( );

Notes and Hint:

1. You should write and test your methods one at a time.
