总过四个类：
第一个类：Poker

public class Poker {
//扑克类
    public String desgin;// 花色
    public String num;// 牌值

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((desgin == null) ? 0 : desgin.hashCode());
        result = prime * result + ((num == null) ? 0 : num.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (!(obj instanceof Poker))
            return false;
        Poker other = (Poker) obj;
        if (desgin == null) {
            if (other.desgin != null)
                return false;
        } else if (!desgin.equals(other.desgin))
            return false;
        if (num == null) {
            if (other.num != null)
                return false;
        } else if (!num.equals(other.num))
            return false;
        return true;
    }

    public Poker(String desgin, String num) {
        this.desgin = desgin;
        this.num = num;
    }

}

第二个类：Player

import java.util.ArrayList;
import java.util.List;

public class Player {
//玩家类
    public String name;
    public int id;
    // 新建一个可以装Poker的集合
    public List<Poker> getcards = new ArrayList<Poker>();

    public Player(int id2, String name) {
        this.id = id2;
        this.name = name;

    }

}

第三个类：PlayerComparator

import java.util.Comparator;
//比较类
public class PlayerComparator implements Comparator<Poker> {

    public int compare(Poker o1, Poker o2) {
        // 花色、牌值从小到大排列
        String[] cardDesign = { "方片", "梅花", "红桃", "黑桃" };
        String[] cardNum = { "2", "3", "4", "5", "6", "7", "8", "9", "10", "J",
                "Q", "K", "A" };
        int temp1 = 0;
        int temp2 = 0;
        for (int i = 0; i < cardNum.length; i++) {
            if (o1.num.equals(cardNum[i]))
                temp1 = 1 + i;
            if (o2.num.equals(cardNum[i]))
                temp2 = 1 + i;
        }
        if (temp1 > temp2) {// 牌值左边大返回-1
            return -1;
        } else if (temp1 == temp2) {// 牌值如果大小相同，比较花色
            for (int i = 0; i < cardDesign.length; i++) {
                if (o1.desgin.equals(cardDesign[i]))
                    temp1 = temp1 + i;
                if (o2.desgin.equals(cardDesign[i]))
                    temp2 = temp2 + i;
            }
            if (temp1 > temp2) {// 花色左边大返回-1
                return -1;
            } else {// 花色右边大返回1
                return 1;
            }
        } else {// 牌值右边大返回1
            return 1;
        }

    }

}

第四个类：GameTest（主测试）

import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Random;
import java.util.Scanner;

public class GameTest {

    public List<Poker> pokerList;
    public Map<Integer, Player> playerMap;
    private Scanner input;

    public GameTest() {
        this.pokerList = new ArrayList<Poker>();
        this.playerMap = new HashMap<Integer, Player>();
        input = new Scanner(System.in);
    }

    /*
     * 创建扑克并洗牌
     */
    public void CreatePoker() {
        String[] desgin = new String[] { "黑桃", "红桃", "梅花", "方块" };
        String[] num = new String[] { "2", "3", "4", "5", "6", "7", "8", "9",
                "10", "J", "Q", "K", "A" };

        for (int i = 0; i < 4; i++) {
            for (int j = 0; j < 13; j++) {
                Poker pk = new Poker(desgin[i], num[j]);
                pokerList.add(pk);
            }
        }
        System.out.println("----------创建扑克牌----------");
        System.out.println("----------扑克牌创建成功!----------");
        for (Poker poker : pokerList) {
            System.out.print("[" + poker.desgin + poker.num + "]");
        }
        System.out.println("----------开始洗牌----------");
        Collections.shuffle(pokerList);// 集合中的乱序方法
        for (Poker poker : pokerList) {
            System.out.print("[" + poker.desgin + poker.num + "]");
        }
        System.out.println("----------洗牌结束!----------");
    }

    /*
     * 创建玩家
     */
    public void CreatePlayer() {

        int i = 0;

            System.out.println("输入ID：");
            int id = 0;
            try {

            } catch (Exception e) {
                System.out.println(e.getMessage());
                continue;
            }
            Player p = playerMap.get(id);

            } else {
                System.out.println("该ID已被占用！");
                continue;// 跳出当前回到循环
            }
        }

    }

    /*
     * 防止输入非整数类型的ID
     */
    private int scanf() throws Exception {
        try {
            int in = input.nextInt();
            return in;
        } catch (Exception e) {

        }
    }

    /*
     * 开始比赛
     */
    public void StarGame() {
        System.out.println("---欢迎玩家：" + playerMap.get(1).name);

        Collections.sort(playerMap.get(1).getcards, new PlayerComparator());
        Collections.sort(playerMap.get(2).getcards, new PlayerComparator());

}

运行结果：（为了便于验证代码的正确性，将洗好的顺序和发牌时玩家得到的牌顺便一起打印出来了！）
