Question

Add the following method below to the CardDeck class, and create a test driver to show that they work correctly.

int cardsRemaining() //returns a count of the number of undealt cards remaining in the deck.

Complete in Java programming language.

// Models a deck of cards. Includes shuffling and dealing.

//----------------------------------------------------------------------

package Homework4;

import java.util.Random;

import java.util.Iterator;

import javax.swing.ImageIcon;

public class CardDeck {

public static final int NUMCARDS = 52;

protected ABList<Card> deck;

protected Iterator<Card> deal;

public CardDeck() {

deck = new ABList<Card>(NUMCARDS);

ImageIcon image;

for (Card.Suit suit : Card.Suit.values())

for (Card.Rank rank : Card.Rank.values()) {

image = new ImageIcon("./src/Homework4/cards/" + suit + "_"

+ rank + "_RA.gif");

deck.add(new Card(rank, suit, image));

}

deal = deck.iterator();

}

public void shuffle()

// Randomizes the order of the cards in the deck.

// Resets the current deal.

{

Random rand = new Random(); // to generate random numbers

int randLoc; // random location in card deck

Card temp; // for swap of cards

for (int i = (NUMCARDS - 1); i > 0; i--) {

randLoc = rand.nextInt(i); // random integer between 0 and i - 1

temp = deck.get(randLoc);

deck.set(randLoc, deck.get(i));

deck.set(i, temp);

}

deal = deck.iterator();

}

public boolean hasNextCard()

// Returns true if there are still cards left to be dealt;

// otherwise, returns false.

{

return (deal.hasNext());

}

public Card nextCard()

// Precondition: this.hasNextCard() == true

//

// Returns the next card for the current 'deal'.

{

return deal.next();

}

}
