本文實例為大家分享了java實現(xiàn)簡單石頭剪刀布游戲的具體代碼，供大家參考，具體內容如下

問題描述

Alice, Bob和Cindy一起玩猜拳的游戲。和兩個人的猜拳類似,每一輪,他們會從石頭、剪刀、布中各自選一個出拳,基本的勝負規(guī)則是石頭贏剪刀、剪刀贏布、布贏石頭。如果一輪中正好可以分成勝負兩邊,則負邊的每個人要支付給勝邊的每個人一塊錢。如果無法分成勝負兩邊,則都不出錢。比如,如果Alice出石頭,而Bob和Cindy都出布,則Alice要分支付Bob和Cindy一塊錢。再如,如果Alice出石頭, Bob出剪刀, Cindy出布,則都不出錢。他們三人共進行了n輪游戲,請問最后每個人凈賺多少錢?即賺的錢減去支付的錢是多少?
