尝试了很多方法没搞出来，后来终于成功了，改进了一下：自定义玩家人数。-原创手记-慕课网

方法肯定不是最优的，不过最终功能是能实现的。
讲一下思路：一个List集合用来存放玩家，一个Map集合用来存放，扑克牌的键，以及键值（权和名字），另外一个List用来存放玩家摸到的牌的权和花色。
代码如下：
//一个扑克牌类
package com.pukepai;

public class puke {
public int id;
public String name;
public puke(int id,String name){
this.id=id;
this.name=name;
}
}
//一个玩家类
package com.pukepai;

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

public class user {
public String id;
public String name;
public List <puke> str;
public user(String id,String name){
this.id=id;
this.name=name;
this.str=new ArrayList<puke>();
}
}
//最终是实现类
package com.pukepai;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;
