无法识别连接4个java水平

Question

除了我的水平取胜条件之外，所有的东西都可以工作，我发现这很奇怪，因为我的垂直方向工作得很好，但是我不能解释为什么水平方向的取胜条件不能，但是我的垂直取胜条件可以假设你可以为行和列切换for循环，反之亦然，但是它似乎在这里失败了。

我试着查找资料，但到处都在说要做我已经做过的事情

Answer 1

在您的电路板设置中，您具有：

 if (j% 2 == 0) f[i][j] ="|";

换句话说，您的列在"R"/"Y"/“”播放位置和"|“列标记之间交替。

所以你永远不能在一条水平线(或对角线)上有4个"R“或”Y“--你应该有"R"，"|"，”R“。

更好的方法是从数组中删除"|“--你不需要存储它们，这真的会使你的所有处理变得复杂。只需让数组存储您的棋子，并且仅在打印输出时使用"|“。
