Question

我真的需要帮助，我浪费了很多时间搞清楚。所以我试图制作一个游戏，游戏板表示为数组。当我到达文件的右侧时，一切都完美地运行，创建了新的行。像那样：

 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 X 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
d
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 X 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
d
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 X 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
 0 0 0 0 0 0 0 0 0 0 0
d
Invalid move

Answer 1

您将field字符串拆分为空格，因此“0 \ n”被视为一个标记。因此，当您替换字段中的最后一个元素时，也可以替换新行。

java，gameboard创建一个不需要的新行
