How can I make my PokerHand class randomly deal a thousand hands? - poker

Question

public class PokerHand
{
// ArrayList for cards
private ArrayList<Card> cards;
/**
* Constructor for class Pokerhand
*/
public PokerHand()
{
cards = new ArrayList<Card>(); // arrayList of cards
}
/**
* Add cards to list
*/
public void addCard(Card card1, Card card2, Card card3)
{
cards.add(card1);
cards.add(card2);
cards.add(card3);
}
}
This is my Card Class
public class Card()
{
private int value;
private int suit;
private static String[] suits = { "hearts", "spades", "diamonds", "clubs" };
private static String[] values = { "Ace", "2", "3", "4", "5", "6", "7",
"8", "9", "10", "Jack", "Queen", "King" };
public static String valueAsString( int value ) {
return values[value];
}
Card(int suit, int rank)
{
this.value=value;
this.suit=suit;
}
public String toString()
{
return values[value] + " of " + suits[suit];
}
public int getValue() {
return value;
}
public int getSuit() {
return suit;
}
}
How can I deal a 1000 three card hands? I am stuck on how a variety of things, including what additional methods I need. How can I construct a deal method and how can I make the deal method dish out a thousand random hands while shuffling every time a hand is dealt?

Answer 1

All of these are implementations are based on code from my card library.
Shuffle
public Card[] shuffle(Card[] deck) {
Random gen = new Random();
boolean[] added = new boolean[deck.length];
int positionToAdd = gen.nextInt(deck.length);
Card[] newDeck = new Card[deck.length];
for (int i = 0; i < deck.length; i++) {
while (newDeck[i] == null) {
if (!added[positionToAdd]) {
newDeck[i] = deck[positionToAdd];
positionToAdd = gen.nextInt(deck.length);
added[i] = true;
} else {
positionToAdd = gen.nextInt(deck.length);
}
}
}
return newDeck;
}
Implementation
ArrayList<Card> dealFrom = new ArrayList<Card>();
PokerHand[] hands = new PokerHand[1000];
/*Populate the "dealFrom" yourself here*/
dealFrom = Array.asList(shuffle(dealFrom.toArray()));
for (int i = 0; i < 3000; i += 3) {
//Write your deal method here
hands[i] = new PokerHand(dealFrom[i], dealFrom[i + 1], dealFrom[i + 2]);
}
Hope this helps.
