案例介绍
|
||
按照斗地主的规则，完成洗牌发牌的动作。(洗牌打乱Collections.shuffle()只能打乱list集合)
|
||
具体规则：
|
||
组装54张扑克牌将54张牌顺序打乱
|
||
三个玩家参与游戏，三人交替摸牌，每人17张牌，最后三张留作底牌。（创建4个集合，3个玩家，1个底牌）
|
||
查看三人各自手中的牌（按照牌的大小排序）、底牌【自然排序或者比较器Comparable Comparator】
|
||
规则：手中扑克牌从大到小的摆放顺序：大王,小王,2,A,K,Q,J,10,9,8,7,6,5,4,3【打印牌即可】
|
||
|
||
54键----“大王”
