java发牌代码怎么打 java 发牌的按照花色输出

java斗地主发牌程序

DeckOfCards()构造函数里面，注释掉的

//deck[count]=new Card(faces[count%13],suits[count/13]);

是对的，下面那行除17是错的

另外，没有把大小王赋值到数组里

最后main函数里，打印方法错了。应该为，原本少了一个%-20s

System.out.printf("%-20s%-20s%-20s\n", myDeckOfCards.dealCard(), myDeckOfCards.dealCard(), myDeckOfCards.dealCard());

发牌完成以后剩下的3张牌就是保留的底牌

Q1: 用java ArrayList集合编写扑克牌洗牌与发牌

import java.util.ArrayList;

import java.util.Random;

public class PokerDemo {

ArrayListCard poker = new ArrayListCard();

Player[] players;

int n = 4;

String[] name = {"Wang", "Zhang", "Li", "Yuan"};

public PokerDemo() {

players = new Player[n];

for(int i = 0; i players.length; i++)

players[i] = new Player(name[i]);

for(int i = 0; i 4; i++)

for(int j = 0; j 13; j++)

poker.add(new Card(i, j));

System.out.println("洗牌前: " + poker);

xipai();

System.out.println("洗牌后: " + poker);

fapai();

System.out.println("发牌后: ");

for(int i = 0; i players.length; i++)

System.out.println(players[i]);

}

public void xipai() {

Random r = new Random();

ArrayListCard tmp = new ArrayListCard();

while(!poker.isEmpty()) {

int index = r.nextInt(poker.size());

Card card = poker.get(index);

tmp.add(card);

poker.remove(index);

}

poker = new ArrayListCard(tmp);

}

public void fapai() {

int p = 0;

while(!poker.isEmpty()) {

Card card = poker.get(0);

players[p].add(card);

p = (p + 1) % n;

poker.remove(0);

}

}

public static void main(String[] args) {

new PokerDemo();

}

}

class Card {

int val, sty;

final String[] value = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};

final String[] style = {"黑桃", "红心", "梅花", "方块"};

public Card(int s, int v) {

sty = s;

val = v;

}

public String toString() {

return style[sty]+ " " + value[val];

}

}

class Player {

ArrayListCard cards = new ArrayListCard();

String name;

public Player(String n) {

name = n;

}

public void add(Card card) {

cards.add(card);

}

public String toString() {

return name + ":\t" + cards;

}

}

Q2: 用java程序编写一个发牌的程序。。。跪求了。。。。

1、设计二维数组a[13][4],13代表2,3,4,5,...,K,A ， 4代表红黑方梅 13*4=52

2、这样a[0][0]就是红桃2，a[12][3]就是梅花A

按照这么来随机发牌就很简单了，直接随机个一个a[i][j]就可以了。i和j都分别在13和4以内

思路明确了，代码还是自己写比较好
