JAVA入门第三季代码：简易扑克牌游戏 @long_l

游戏规则：2名玩家，每人随机拿2张牌，取各自大的那张，进行比较，得出获胜者。
共52张牌，没有大小王。先比较点数，若点数相同则比较花色。
从大到小为：A,K,Q,J,10，9，8，7，6，5，4，3，2
从大到小为："黑桃","红桃","梅花","方块“”
Cards

Compare

//用来比较2个人手牌的大小，得出获胜者。

测试

package com.imooc;
//测试窗口。
public class Test {
    public static void main(String[] args) {    
         Cards aq=new Cards("a","a");//创建1个对象，用来调用方法
         Plays aw=new Plays("aa");      //创建1个对象，用来调用方法
         aq.creatCards();       
         aw.creatPlays();       
        aw.getHandCards(aw.play, aw.play1, aq.newCards);
         Compare.compare(aw.play, aw.play1, aq.newCards1);
