Java入门第三季 简易扑克牌游戏

游戏中先创建扑克牌对象，然后创建玩家，并给玩家发牌，然后显示玩家手中的牌，最后对玩家手中的牌比较大小。
定义了一个玩家类Gamer

package com.payingCard;
import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
//为游戏创建玩家
public class Gamer {
    public int Id ;
    public String Name;
    List<String> myCards;
    public Gamer(){
    }
    public Gamer(int Id,String Name){
        this.Id = Id;
        this.Name = Name;
        this.myCards =new ArrayList<String>();
    }
}
