我正在做一个TicTacToe计划，唯一缺失的部分是让用户选择是否退出游戏或重放。我找不到一种“回归”游戏的方式。如何返回游戏？完成游戏后

独立于您的问题，您可能需要考虑重写此代码以消除对pick1，pick2，pick9变量的需求。如果你发现自己编写了一个看起来像这样的变量集合，那么你几乎总是可以通过使用一个数组来重写它，如`int [] pick = new int [9]`。这允许您以`pick [0]`，...，`pick [8]`的形式访问所有值，但更重要的是，它可以让您以编程方式生成索引。如果你愿意花时间，这可以让你将`switch`语句压缩成只有几行代码。 – templatetypedef 2011-01-24 22:27:18

一些提示，r1-r9，pick1-pick9，使用数组来代替，与你的cs一样，将它们改为一个字符串数组，然后像这样初始化它们c [0] =“741”; – hhafez 2011-01-24 22:28:53
