我在java中制作了一个Tic Tac Toe游戏。我已经完成了代码，但我不确定如何查看对角线中是否有赢家。我试图提出的是：
win[x] += (board[0][2] + board[1][1] + board[2][0]);
x++;
win[x] += (board[0][0] + board[1][1] + board[2][2]);
然而它似乎没有起作用。非常感谢帮助解决这个问题！

在Java中，由于char是基本类型，因此它被存储为数字。因此，当你执行('O' + 'O' + 'O')时，实际上最终会将o的ascii值加在一起3次，结果只会产生一个字符。要解决此问题，您可以强制Java将+运算符视为连接而不是添加：("" + 'O' + 'O' + 'O')

这段代码最容易！ 这有赢得逻辑，损失逻辑，绘制逻辑以及分数，重置和新游戏！
