java二维ArrayIndexOutOfBoundsException

我正在做一个学校项目，包括制作一个尺寸可调的井字游戏。我的按键处理代码中遇到错误：

我通常认为这是由于调用数组设置参数之外的索引造成的，但我在代码中找不到这一点：

void b(int n)
{
    // code to change n to array indices
    // indice positions
    int x = 0;
    int y = 0;

    int counter = 1;

    for (int i = 0; i <= (d - 1); i++)
    {
        for (int j = 0; j <= (d - 1); j++)
        {
            if (n == counter)
            {
                x = j;
                y = i;
                gui.blank1.setText("" + x + " " + y + "\n"); // debugging
                break; // values found, exit loop
            }
            else
            {
                // increment counter
                counter ++;
            }
        }
    }
    counter = 1;

    clicks++;
    if ((clicks % 2) == 1) // not divisible by two
    {
        gui.boxes[x][y].setIcon(a);
        check[x][y] = 1;
    }
    else
    {
        gui.boxes[x][y].setIcon(b);
        check[x][y] = 2;
    }

    winner();
}

void b（int n）
{
//将n更改为数组索引的代码
//标记位置
int x=0；
int y=0；
int计数器=1；
对于（int i=0；i您的stacktrace表示超出边界的索引为0。为了实现这一点，数组的长度必须为零。因此，
gui.box.length
为零，或者对于
x
的某个值，
gui.box[x].length
为零。请同时选中这两个选项。
欢迎使用堆栈溢出！看起来您需要学习使用调试器。请自行解决一些问题。如果以后仍有问题，请随时返回以演示您的问题。您还需要学习读取堆栈跟踪。与随机查找问题不同，read it：它告诉您问题发生在TicTacEvent.java的第109行。进一步读取异常（实际上是第1行），它表示导致异常的索引的值为零（0）-显然数组是以零容量创建的，如
新对象[0]
