/*
                功能描述
   1.创建一副扑克牌
   包括4种花色：黑桃，红桃，梅花，方块
   十三中点数：2-10，J,Q,K,A
   2.创建两名玩家
   玩家至少要有ID，姓名，手牌等属性，手牌为扑克牌的集合
   3.洗牌
   将之前创建的“一副扑克牌”打乱顺序
   4.发牌
   讲洗牌之后的扑克牌集合，从第一张开始，发给两名玩家，按照一人一张的方式，每人发两张
   5.游戏
   比较两个人手中的扑克牌，规则为：取两人各自手中点数最大牌进行比较，点数大的赢；
   如果两个人各自的点数相等，则按花色比较

结果会不一样
- 本代码的难点是重写compareTo()方法，我们按照自己的想要的规则定义后就可以进行排序了
- 尽量以private的形式定义变量，再以Get()andSet()函数调用变量
