编程语言对错误是不可原谅的,它迫使我们必须严格和谨慎 您的代码很难阅读,因此我们和您都需要调试,从到处都是的缩进开始,但也有一些粗心的错误,尤其是这个错误:
for (int r = 0; r < board.length; rows++)
这就是我的建议:
String move(char x, int rows, int columns) {
String b = "";
// creates a vertical bar at the beginning and the end of each row
for (int r = 0; r < board.length; r++) {
b += "| ";
for (int c = 0; c < board[r].length; c++) {
// let's check to see what the variables hold!
System.out.printf("rows: %d, columns %d, r: %d, c: %d%n", rows, columns, r, c);
b += board[rows][columns] + " "; // **** the offending line ****
因此,这里的column变量保存值3并导致数组爆炸。您需要回溯以了解如何调用此方法,以及为什么它将3传递到列parmaeter中
编辑2在重新审阅您的最新帖子时,您仍然在硬编码您的移动方法,以接受3作为列参数:
game.move('x', 1, 3);
首先要解决这个问题。这个参数不可能是3。编程语言对错误是不可原谅的,并迫使我们严格和谨慎 您的代码很难阅读,因此我们和您都需要调试,从到处都是的缩进开始,但也有一些粗心的错误,尤其是这个错误:

首先要解决这个问题。参数不能为3。好吧,我仍然收到相同的错误消息…我似乎无法理解@HovercraftFullOfEels查看我的我跟踪了你关于循环的消息…如果我将它切换到行,我将得到一个重复的变量消息。所以我只是把它们做成了r,cit仍然指向相同的线条……TictoBoard中的75和TictoE中的24:)我所有的大括号都匹配,并且缩进,以便我能理解,但我仍然得到了我之前用线条告诉你的相同信息,我仍然收到相同的错误消息…我似乎无法理解@HovercraftFullOfEels查看我的我跟踪了你关于循环的消息…如果我将它切换到行,我将得到一个重复的变量消息。所以我刚把它们改成了r,cit仍然指向同一行……TictoeBoard中的75行和TictoE中的24行:)我所有的大括号都匹配,并且缩进以便我能理解,但我仍然得到了我之前告诉你的相同的信息,即线数组索引以
