Java入门第三季，扑克牌游戏

Poker类：
定义扑克牌的花色，大小属性；
定义如何判断两张扑克牌的大小的方法（先判断扑克牌的ID,然后判断花色，具体实现过程是在colourSize()和idSize()两个方法中）；

package com.imooc.pokergame;

public class Poker {
    public String colour;
    public String id;

    public Poker(String colour,String id){
        this.colour=colour;
        this.id=id;
    }
    /**
     * 通过for循环遍历当前扑克牌的ID值，记录他们在colours中的索引位置
     * 通过比较索引位置，得出牌的ID大小，如果当前对象的ID ①大，返回1;  ②相同，返回0; ③ 小，返回-1
     * @return
     */
    public int idSize(Poker poker){
        int thisIdLocation = 0;
        int parameterIdLocation = 0;
        String [] id = {"2","3","4","5","6","7","8","9","10","J","Q","K","A"};
        for(int i = 0;i < id.length;i++){
            if(this.id.equals(id[i])&&poker.id.equals(id[i])){
                thisIdLocation=parameterIdLocation=i;
            }else{
            if(this.id.equals(id[i])){
                thisIdLocation = i;
            } else {
                if(poker.id.equals(id[i])){
                    parameterIdLocation = i;
                } else {
                    continue;
                }
            }
        }
        }
        if(thisIdLocation > parameterIdLocation){
            return 1;
        } else {
            if(thisIdLocation == parameterIdLocation){
                return 0;
            } else {
                return -1;
            }
        }
    }

    /**
     * 用语idSize()返回0之后，再执行此方法
     * 在for循环中遍历当前扑克牌和参数扑克牌的花色，记录它们在colours中的索引位置
     * 如果当前扑克牌>参数扑克牌，返回1；否则返回-1；
     * @return
     */
    public int colourSize(Poker poker){
        int thisColourLoction = 0;
        int parameterColourLocation = 0;
        String [] colours ={"黑桃","红桃","梅花","方片"};
        for(int i = 0;i < colours.length;i++){
            if(this.colour.equals(colours[i])){
                thisColourLoction = i;
            } else {
                if(poker.colour.equals(colours[i])){
                    parameterColourLocation = i;
                } else {
                    continue;
                }
            }
        }
        if(thisColourLoction < parameterColourLocation)
            return 1;
        else
            return -1;
        }
    }

Player类：
定义玩家的ID,姓名，和他们手中的扑克牌序列（List类型）

package com.imooc.pokergame;

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

public class Player {
    public int id;
    public String name;
    public List<Poker> pokers;

    public Player(int id,String name){
        this.id=id;
        this.name=name;
        this.pokers = new ArrayList<Poker>();
    }

}

测试类：
定义方法（创建扑克牌、洗牌、创建玩家、发牌、开始游戏）{PS：老实的说，其实最艰难的还是（开始游戏）这个方法比较难写，原来最开始在测试类中把玩家player的类型写成了Set类型，在写（开始游戏）这个方法的时候，因为Set的实现类没有get方法，不知道如何把玩家的name属性读出来，所以换成了List类型，在此，请教各位大神如何编写源码？}

package com.imooc.pokergame;

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import java.util.Random;
