大家都完玩过斗地主，一副牌有什么组成呢？

答案是：一个牌盒和54张牌；54张牌有2到A各四种花色张加两张大小王

代码如下

String[] colors={"黑色","红桃","梅花","方块"};
String[] nums={"A","2","3","4","5","6","7","8","9","10","J","Q","K"};
String[] puke = new String[54];

现在我们需要把数字和花色拼接构成除开大小王，这里我们将运用到遍历

遍历方法

 int k = 0;
        for (int i = 0; i < nums.length; i++) {
            for (int a = 0; a < colors.length; a++) {
                String card = colors[a] + nums[i];
                puke[k] = card;
                k++;
                puke[52] = "小王";
                puke[53] = "大王";

            }
        }

现在我们的牌已经做好了，打牌你得洗牌

  //洗牌
            Random random = new Random();
            for (int i = puke.length - 1; i > 1; i--) {
                int j = random.nextInt(i);
                String t = puke[i];
                puke[i] = puke[j];
                puke[j] = t;

最后一步就是分牌，这里不单独表示，全部代码

mport java.util.Arrays;
import java.util.Random;

public class Demo03 {
    public static void main(String[] args) {
        String[] nums = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "A", "K", "Q", "J"};
        String[] colors = {"黑色", "红桃", "梅花", "方块"};
        String[] puke = new String[54];

        int k = 0;
        for (int i = 0; i < nums.length; i++) {
            for (int a = 0; a < colors.length; a++) {
                String card = colors[a] + nums[i];
                puke[k] = card;
                k++;
                puke[52] = "小王";
                puke[53] = "大王";

            }
        }


            //洗牌
            Random random = new Random();
            for (int i = puke.length - 1; i > 1; i--) {
                int j = random.nextInt(i);
                String t = puke[i];
                puke[i] = puke[j];
                puke[j] = t;


            }
            String[] player1 = new String[17];
            String[] player2 = new String[17];
            String[] player3 = new String[17];
            String[] dipai = new String[3];
            dipai[0] = puke[53];
            dipai[1] = puke[52];
            dipai[2] = puke[51];

            for (int i = 0; i < 17; i++) {
                player1[i] = puke[i * 3];
                player2[i] = puke[(i * 3) + 1];
                player3[i] = puke[(i * 3) + 2];
            }


            for (String er1 : player1) {
                System.out.print(er1 + " ");
               


            }
            System.out.println();
            for (String er2 : player2) {
                System.out.print(er2 + " ");

            }
            System.out.println();
            for (String er3 : player3) {
                System.out.print(er3 + " ");
            }
            System.out.println();
            for (String c : dipai) {
                System.out.print(c + " ");
            }
        }
    }

随机抽取一张作为地主牌host

import java.util.Arrays;
import java.util.Random;

public class Demo03 {
    public static void main(String[] args) {
        String[] nums = {"2", "3", "4", "5", "6", "7", "8", "9", "10", "A", "K", "Q", "J"};
        String[] colors = {"黑色", "红桃", "梅花", "方块"};
        String[] puke = new String[54];
//成牌
        int k = 0;
        for (int i = 0; i < nums.length; i++) {
            for (int a = 0; a < colors.length; a++) {
                String card = colors[a] + nums[i];
                puke[k] = card;
                k++;
                puke[52] = "小王";
                puke[53] = "大王";

            }
        }


        //洗牌
        Random random = new Random();
        for (int i = puke.length - 1; i > 1; i--) {
            int j = random.nextInt(i);
            String t = puke[i];
            puke[i] = puke[j];
            puke[j] = t;


        }
//随机抽取一张牌作为地主牌

        String[] host = new String[1];
        for (int d = puke.length - 1; d > 1; d--) {
            int j = random.nextInt(d);
            host[0] = puke[j];
        }
//设置3位玩家以及底牌
        String[] player1 = new String[17];
        String[] player2 = new String[17];
        String[] player3 = new String[17];
        String[] dipai = new String[3];
        dipai[0] = puke[53];
        dipai[1] = puke[52];
        dipai[2] = puke[51];
//这里无法理解,建议画图，
//puke数组的0号索引给1号玩家   得出规律1号玩家的牌是3 的倍数
//puke数组的1号索引给2号玩家   得出规律1号玩家的牌是3 的倍数加1
//puke数组的2号索引给3号玩家   得出规律1号玩家的牌是3 的倍数加2

        for (int i = 0; i < 17; i++) {
            player1[i] = puke[i * 3];
            player2[i] = puke[(i * 3) + 1];
            player3[i] = puke[(i * 3) + 2];
        }
            //后面遍历出来

        for (String er1 : player1) {
            System.out.print(er1 + " ");



        }
        System.out.println();
        for (String er2 : player2) {
            System.out.print(er2 + " ");

        }
        System.out.println();
        for (String er3 : player3) {
            System.out.print(er3 + " ");
        }
        System.out.println();
        for (String c : dipai) {
            System.out.print(c + " ");
        }
        System.out.println();
        for (String hosts : host) {
            System.out.println(hosts + " ");
        }
    }
}

如果你后面想实现知道谁是地主的操作，那么你可以利用equals来对字符串进行比较，来知道谁是地主，这里我不做演示了
