一个简单的扑克牌小程序(java第三季的最后一个练习)

新手一枚，最近刚学了java的集合框架，就拿来用一用（水平有限，欢迎交流）
游戏规则是：取两人各自手中点数最大的牌进行比较，点数大的赢；若两人各自的点数相等，则按花色比较。

感觉主要是以下几个方面花了一些时间，
（打乱扑克顺序的洗牌，通过自定义规则比较大小，一些集合与泛型的使用，通过try..catch捕获异常来限定登录ID为整数。）

首先是Card类：

/** 
 * 扑克牌类 
 * @author admin 
 * 
 */  

public class Card{  

    //  花色：suit  
    //点数：figure  

    public String suit;  
    public String figure;  

    /** 
     * 形参构造器 
     * @param suit 
     * @param figure 
     */  
    public Card(String suit,String figure){  
        this.suit = suit;  
        this.figure = figure;  
    }  

}  

玩家Player类：

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

/** 
 * 玩家类 
 * @author admin 
 * 
 */  
public class Player {  

    public int id;  
    public String name;  

    //手牌为扑克牌的集合,泛型设定为Card  
    public List<Card> cards;  

    public Player(){  
        this.cards = new ArrayList<Card>();  
    }  
  }  

最后是test：

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

public class Test {  

    public Scanner console;  
    //用于存放所有扑克的集合  
    public List<Card> AllCards;  

    Player player1 = new Player();  
    Player player2 = new Player();  

    String[] suits = {"方块","梅花","红心","黑桃"};  
    String[] figures = {"2","3","4","5","6","7","8","9","10","J","Q","K","A"};  

    public Test(){  
        console = new Scanner(System.in);  
        this.AllCards = new ArrayList<Card>();  
    }  

    /** 
     * 玩家登录 
     */  
    void login(){  
        System.out.println("这里是登录界面：");  
        //通过try——catch捕获异常，限制输入ID为整数  
        while(true){  
            try{  
                System.out.println("请输入第一个玩家的ID（限为数字）：");  
                String testid = console.next();  
                player1.id=Integer.parseInt(testid);  
                break;  
            }catch(NumberFormatException e){  
                System.out.println("请输入正确的ID!");  
             }  
        }  
        System.out.println("请输入第一个玩家的昵称：");  
        player1.name = console.next();  

        while(true){  
            try{  
                System.out.println("请输入第二个玩家的ID（限为数字）：");  
                String testid = console.next();  
                player2.id=Integer.parseInt(testid);  
                break;  
            }catch(NumberFormatException e){  
                System.out.println("请输入正确的ID!");  
             }  
        }  
        System.out.println("请输入第二个玩家的昵称：");  
        player2.name = console.next();  
    }  

    /**
