我正在尝试为我的一个课程用 Java 创建一个井字游戏。该程序从命令行获取一个 int 并创建一个该大小的 JButton 二维数组。它还有一个撤消和一个新的游戏按钮。该程序编译并运行，当我单击新游戏按钮时没有发生异常，但是当我单击其中一个游戏空间时，它会抛出此异常。

我的 newMove 方法只是获取按钮和转弯（1 或 2）的 x 和 y 位置，并将其添加到与 GameTester 类关联的 2D int 数组中。

public void newMove(int x, int y, int turn)
    {
    board[x][y] = turn;
}

这是我的 ActionListener 中循环的一部分，其中包括调用 newMove 方法的位置。

 if (event == buttons[x][y])
{
    theBoard.moveLog(x,y);
    theBoard.newMove(x,y,toggle);
    if (toggle == 1)
    {
        buttons[x][y].setText("X");
        toggle = 2;
    }
    else
    {
        buttons[x][y].setText("O");
        toggle = 1;
    }
            ..... 
    }

任何帮助是极大的赞赏！:)

从您提供的内容来看，问题很可能buttons不是board相同尺寸的数组。尝试使用变量来设置两种尺寸或使用一个来设置另一个以确保它们的尺寸相同。

选项1

int X = 3, Y = 3;

JButton[][] buttons = new JButton[X][Y];
char[][] board = new char[X][Y];

选项 2

int X = 3, Y = 3;

JButton[][] buttons = new JButton[X][Y];
char[][] board = new char[buttons.length][buttons[0].length];

如果不是这种情况，那么您需要提供一个简短的、独立的、可编译的问题示例，以便我们了解发生了什么。
