思路
创立一个HashMap汇合用于记录54张牌
- {0=♥2, 1=♦2, 2=♣2, 3=♠2, 4=♥3, 5=♦3, ... , 50=♣A, 51=♠A, 52=大王, 53=小王}
- HashMap汇合的key值记录54张牌的程序
- 创立一个一般ArrayList汇合用于记录54个数字，对应HashMap的54个Key值
- 打乱整个ArrayList汇合（洗牌）
创立四个TreeSet汇合（三个玩家汇合和底牌汇合），依照一人一张的程序别离将张牌的Key值存入三个玩家汇合中，最初三张非凡解决存入底牌汇合。
- 应用TreeSet汇合存牌的起因是因为TreeSet汇合自带排序功能。
- 依据四个TreeSet汇合记录的Key值获取HashM汇合中映射的value值
