我是Java和编程的新手，我正在尝试制作摇滚纸剪刀Big Bang的电视节目风格。我目前只是坚持一些事情，我希望得到一些帮助。我目前遇到了结束分层while循环的问题，所以当胜利者赢了2场比赛时它结束了。此外，我的用户输入有问题。任何帮助，将不胜感激。这是我目前的代码。

如果你拿出你的while（true）循环，它应该在以太玩家赢2时停止游戏
如果没有其他许多，你可以使这一点变得更容易。如果创建一个像5-Sc，4-P，3-R，2-L，1-S的地图（hashmap），你可以看到一个获胜的模式。如果差异是均匀的，那么第一次获胜。如果差异是奇数，那么第二个胜利。例如P - R = 1 - 纸覆盖岩石，Sc - L = 3 - 剪刀斩首蜥蜴，R - S = 2 - 在这种情况下Spock vaporaze rock和第二次获胜。 （如果答案是否定的话，它都会反转）并且摆脱双循环，1就足够了
