I need to modify DeckOfCardsTest.java to deal a five-card poker hand. Then modify class DeckOfCards to include methods that determine whether a hand contains:

a) a pair

b) two pairs

c) three of a kind

d) four of a kind

e) a flush (all card of the same suit)

f) a straight

g) a full house

This will include adding methods to the Card class for getFace and getSuit. I am not allowed to use ArrayList, Sets, or any other built-in devices. This means if you have to import anything other than the random number generator, it is not allowed.

Please do not copy the incorrect answers from other similar questions.

I believe that the "super" statement can be used here, but I have not figured out how.

The code for the three files is as follows:

----------------------------------------------------------------------------------------------

DeckoOfCardsTest.java

public class DeckOfCardsTest { // execute application public static void main(String[] args) { DeckOfCards myDeckOfCards = new DeckOfCards(); myDeckOfCards.shuffle(); // place Cards in random order // print the hand dealt for (int i = 1; i <= 5; i++) { // deal and display a Card System.out.printf("%-19s%n", myDeckOfCards.dealCard());

if (i % 5 == 0) { // output a newline after every fifth card, incase dealing 2 hands in the future System.out.println(); } }//end of for loop } //end of main }//end of class

------------------------------------------------------------------------------------

Card.java

public class Card { private final String face; // face of card ("Ace", "Deuce", ...) private final String suit; // suit of card ("Hearts", "Diamonds", ...)

// two-argument constructor initializes card's face and suit public Card(String cardFace, String cardSuit) { this.face = cardFace; // initialize face of card this.suit = cardSuit; // initialize suit of card }

// return String representation of Card public String toString() { return face + " of " + suit; } }

------------------------------------------------------------------------------------------------------

DeckOfCards.java

import java.security.SecureRandom;

public class DeckOfCards { // random number generator private static final SecureRandom randomNumbers = new SecureRandom(); private static final int NUMBER_OF_CARDS = 52; // constant # of Cards

private Card[] deck = new Card[NUMBER_OF_CARDS]; // Card references private int currentCard = 0; // index of next Card to be dealt (0-51)

// constructor fills deck of Cards public DeckOfCards() { String[] faces = {"Ace", "Deuce", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Jack", "Queen", "King"}; String[] suits = {"Hearts", "Diamonds", "Clubs", "Spades"};

// populate deck with Card objects for (int count = 0; count < deck.length; count++) { deck[count] = new Card(faces[count % 13], suits[count / 13]); } }

// shuffle deck of Cards with one-pass algorithm public void shuffle() { // next call to method dealCard should start at deck[0] again currentCard = 0;

// for each Card, pick another random Card (0-51) and swap them for (int first = 0; first < deck.length; first++) { // select a random number between 0 and 51 int second = randomNumbers.nextInt(NUMBER_OF_CARDS);

// swap current Card with randomly selected Card Card temp = deck[first]; deck[first] = deck[second]; deck[second] = temp; } }

// deal one Card public Card dealCard() { // determine whether Cards remain to be dealt if (currentCard < deck.length) { return deck[currentCard++]; // return current Card in array } else { return null; // return null to indicate that all Cards were dealt } } }
