java实现简单石头剪刀布游戏

本文实例为大家分享了java实现简单石头剪刀布游戏的具体代码，供大家参考，具体内容如下

问题描述

Alice, Bob和Cindy一起玩猜拳的游戏。和两个人的猜拳类似,每一轮,他们会从石头、剪刀、布中各自选一个出拳,基本的胜负规则是石头赢剪刀、剪刀赢布、布赢石头。如果一轮中正好可以分成胜负两边,则负边的每个人要支付给胜边的每个人一块钱。如果无法分成胜负两边,则都不出钱。比如,如果Alice出石头,而Bob和Cindy都出布,则Alice要分支付Bob和Cindy一块钱。再如,如果Alice出石头, Bob出剪刀, Cindy出布,则都不出钱。他们三人共进行了n轮游戏,请问最后每个人净赚多少钱?即赚的钱减去支付的钱是多少?
