Thread: Dealing 13 cards to 4 players.

How would I deal 13 cards to 4 players? I have my program below, but I'm stuck.

This is my work so far. I'm new to this programming but I'm trying! I know there are a lot of things wrong with this, but bear with me I'm learning.

public class Project_BridgeDeal {
	static String[] suits = {"Spades", "Hearts", "Diamonds", "Clubs"};
	static String[] ranks = {"2", "3", "4", "5", "6", "7", "8",
				 "9", "10", "Jack", "Queen", "King", "Ace"};
 
	public static void main(String[] args) {
	}
	public static void unwrap(int[] pack) {  	
		int[] deck = new int[52];	
		unwrap(deck);
		for (int i = 0; i < deck.length; i++)
			deck[i] = i; }
 
	public static void shuffle(int[] pack) {  
		shuffle(deck);
		for (int i = 0; i < deck.length; i++) {
			int index = (int)(Math.random() * deck.length);
			int temp = deck[i];
			deck[i] = deck[index];
			deck[index] = temp;
		}
	}
	public static int[] deal(int[] pack, int n, int offset) {  
 
		final int CARDS_PER_HAND = 13;
 
		int[] north = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 0);
		showHand(north, "North was dealt: ");
 
		int[] east = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 1);
		showHand(east, "East was dealt:");
 
		int[] south = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 2);
		showHand(south, "South was dealt:");
 
		int[] west = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 3);
		showHand(west, "West was dealt: ");
	}

I did a program like this before, but without dealing them out.

public class ProgramDeck {
   public static void main(String[] args) {
      String[] suit = { "Clubs", "Diamonds", "Hearts", "Spades" };
      String[] rank = { "2", "3", "4", "5", "6", "7", "8", "9",
                        "10", "Jack", "Queen", "King", "Ace"    };
      int SUITS = suit.length;
      int RANKS = rank.length;
      int N = SUITS * RANKS;
 
      // build the deck
      String[] deck = new String[N];
      for (int i = 0; i < RANKS; i++)
         for (int j = 0; j < SUITS; j++)
            deck[SUITS*i + j] = rank[i] + " of " + suit[j];
 
      // shuffle the deck
      for (int i = 0; i < N; i++) {
         int r = i + (int) (Math.random() * (N-i));
         String t = deck[r];
         deck[r] = deck[i];
         deck[i] = t;
      }
 
      // print the shuffled deck
      for (int i = 0; i < N; i++)
         System.out.println(deck[i]);
   }
}

Here is a sample run of the program:

North was dealt:
2 of Spades
6 of Spades
8 of Spades
2 of Hearts
3 of Hearts
8 of Hearts
10 of Hearts
6 of Diamonds
8 of Diamonds
Queen of Diamonds
King of Diamonds
4 of Clubs
5 of Clubs

East was dealt:
5 of Spades
King of Spades
6 of Hearts
9 of Hearts
Jack of Hearts
Queen of Hearts
Ace of Hearts
2 of Diamonds
4 of Diamonds
10 of Diamonds
Ace of Diamonds
9 of Clubs
Jack of Clubs

South was dealt:
3 of Spades
4 of Spades
9 of Spades
Jack of Spades
Ace of Spades
7 of Hearts
3 of Diamonds
5 of Diamonds
7 of Diamonds
Jack of Diamonds
3 of Clubs
7 of Clubs
King of Clubs

West was dealt:
7 of Spades
10 of Spades
Queen of Spades
4 of Hearts
5 of Hearts
King of Hearts
9 of Diamonds
2 of Clubs
6 of Clubs
8 of Clubs
10 of Clubs
Queen of Clubs
Ace of Clubs

I just did! Thank you for that tip.

What's wrong with the sample run you posted? What do you need help with?

I thought I posted a reply.

I guess maybe my question is in the wrong section. My ProgramDeck is fine, but not Project Bridgedeal. In ProgramDeck, I received 52 random cards. However, I cannot incorporate that into Project Bridgedeal, where I'm suppose to deal 13 random cards to 4 players. I'm new at this, so I don't know how to do it. I think maybe...

for (int i = 0; i < 4; i++) {
String suit = suits[deck[i] / 13];
String rank = ranks[deck[i] % 13];
System.out.println("North was dealt: " + deck[i]);

So I tidied up my code.
I'm still have issues though. How I can make showhand a method to display what cards each player has? Please and thank you.

public class Project_BridgeDeal {
	static String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs" };
	static String[] ranks = { "2", "3", "4", "5", "6", "7", "8", "9", "10",
			"Jack", "Queen", "King", "Ace" };
 
	public static void main(String[] args) {
		int[] deck = new int[52];
		final int CARDS_PER_HAND = 13;
		unwrap(deck);
		shuffle(deck);
		System.out.println();
 
		int[] north = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 0);
		showHand(north, "North was dealt: ");
 
		int[] east = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 1);
		//showHand(east, "East was dealt: ");
 
		int[] south = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 2);
		//showHand(south, "South was dealt:");
 
		int[] west = deal(deck, CARDS_PER_HAND, CARDS_PER_HAND * 3);
		//showHand(west, "West was dealt:");
 
	}
 
	public static void unwrap(int[] pack) {
 
 
		for (int i = 0; i < pack.length; i++)
			pack[i] = i;
	}
 
	public static void shuffle(int[] pack) {
 
 
		for (int i = 0; i < pack.length; i++) {
			int index = (int) (Math.random() * pack.length);
			int temp = pack[i];
			pack[i] = pack[index];
			pack[index] = temp;
		}
	}
 
	public static int[] deal(int[] pack, int n, int offset) {
		int [] hand = new int [13];
		for (int i = 0; i <n; i++)
			hand[i]= pack[i+offset];
 
		return hand;
	}
//Issue starts here
	public static int [] showHand(int[]pack) {
		for (int north; north<13; north++)
			showHand[north]=pack[north];
			return pack;
 
	}
}

Am I on the right track, though?

Or

public static int [] hand(int[]showHand)
for( int north; north < hand; north++)
hand[hand] = showHand[hand]
return show hand;

I just saw the questions, guess you added them.

I believe the input would be hand and showHand. I would say the players( North East South West), but I'm not sure.
The method should return showHand, or display the 13 random cards each player receives.
With the input, the method should I think take the player's hand and display them accordingly.

I'm new so I'm sorry if it sounds like bull. I'm really trying right now.
