24点游戏
24点游戏是经典的纸牌益智游戏。
常见游戏规则：
从扑克中每次取出4张牌。使用加减乘除，第一个能得出24者为赢。（其中，J代表11，Q代表12，K代表13，A代表1），按照要求编程解决24点游戏。
功能：
1.随机生成4个代表扑克牌牌面的数字字母。
2.程序自动列出所有可能算出24的表达式。
3.具有游戏帮助功能。
算法思路：
1.用java的swing来创建窗口UI。
2.把随机产生的四个数字保存在hashSet对象中，然后在从此对象取出这 四个数字当做四张卡牌的号码。
3.利用穷举法列出所有能组成24点的表达式。首先随机确定好了卡牌号 码，然后通过3重循环，组合排列出所有运算符的组合，在第一层循环，对 号码数字进行两两运算，在下层循环，再把这个运算后的结果和后面一个数 进行运算，以此类推。
