本程序使用了ArrayList 、HashMap，简单应用了Java第三季的集合框架

首先创建一个卡牌类

/**
 * 扑克类
 */
public class Poker {
    public Poker(String size,String number){
        this.size=size;
        this.number=number;
    }
    public String getSize(){
        return this.size;
    }
    public String getNumber(){
        return this.number;
    }
    private String size;
    private String number;
}

然后创建一个卡牌玩家类

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

/**
 * 打牌人员类
 */
public class PokerPlayer {
    public PokerPlayer(String id,String name){
        this.id=id;
        this.name=name;
        this.playerpoker = new ArrayList();
    }

    public String getId(){
         return this.id;
    }
    public String getName(){
        return this.name;
    }

    private String id;
    private String name;
    public List playerpoker;
    public String a;
}

最后一个就大杂烩了，流程如下：创建卡牌--遍历卡牌--创建玩家--发牌--比较卡牌；
创建卡牌用ArrayList
遍历卡牌用foreach方法
创建玩家用到了HashMap
发牌过程较简单，仅为随机不重复四个数字
卡牌比较可以扩展一下，我写的比较简单了

import java.util.*;

public class PokerList {
    private List poker;
    private Map player ;
    private int a1,a2,b1,b2;//用来比较
    Scanner in = new Scanner(System.in);
    public PokerList (){
        this.poker = new ArrayList();
        this.player = new HashMap();
    }
    public void addPoker(){
        System.out.println("正在创建卡牌......");
        String[] size={"黑桃","红桃","梅花","方块"};
        String[] number={"A","2","3","4","5","6","7","8","9","10","J","Q","k"};
        for (String a:size) {
            for (String b:number) {
                Poker apoker = new Poker(a,b);
                poker.add(apoker);
            }
        }

    }
    public void pokerforeach(){
        System.out.print("已创建卡牌： ");
        for (Poker pok:poker) {
            System.out.print(pok.getSize()+pok.getNumber()+", ");
        }
        System.out.println("n正在洗牌......");
    }

    public void creatPlayer(){
        int i=0;
        while (ia2)
        amax=a1;
        else amax=a2;
        if (b1>b2)
        bmax=b1;
        else bmax=b2;
        if (amax>bmax)
        System.out.println("玩家一胜利");
        else System.out.println("玩家二胜利");
    }

    public static void main(String[] args){
        PokerList pl= new PokerList();
        pl.addPoker();//创建卡牌
        pl.pokerforeach();//遍历卡牌
        pl.creatPlayer();//创建玩家
        pl.shuttle();//发牌
        pl.comparison();

    }

}
