java - 数组越界，但我不确定为什么？

Question

所以这是我使用的双数组

public int[][] MAP = { { 8, 9, 9, 8, 8, 8, 8, 8, 8, 8, 8 },
        { 8, 8, 9, 9, 8, 8, 8, 8, 8, 8, 8 },
        { 8, 8, 8, 9, 8, 8, 8, 8, 8, 8, 8 },
        { 8, 8, 8, 9, 9, 8, 8, 8, 8, 8, 8 },
        { 8, 8, 8, 8, 9, 8, 8, 8, 8, 8, 8 },
        { 8, 8, 8, 9, 9, 9, 8, 8, 8, 8, 8 },
        { 8, 8, 9, 9, 9, 8, 8, 8, 8, 8, 8 },
        { 8, 8, 8, 9, 9, 9, 8, 8, 8, 8, 8 },
        { 8, 8, 8, 8, 8, 9, 9, 9, 9, 8, 8 },
        { 8, 8, 8, 8, 8, 9, 9, 9, 8, 8, 8 },
        { 9, 8, 8, 8, 8, 8, 9, 9, 9, 8, 8 },
        { 9, 8, 8, 8, 8, 8, 9, 9, 9, 8, 8 },
        { 9, 8, 8, 8, 8, 8, 9, 9, 9, 8, 8 },
        { 9, 8, 8, 8, 8, 8, 9, 9, 9, 8, 8 },
        { 9, 8, 8, 8, 8, 8, 9, 9, 9, 8, 8 } };

我的问题是，当我尝试使用它加载相应的图像时，我收到一条错误消息，指出当 y = 12 时它超出范围。

Image[][] displayedMap = new Image[MAP[0].length][MAP.length];

    public Town() {
        System.out.println("Map len" + MAP.length);
        for (int x = 0; x < MAP[0].length; x++) {
            for (int y = 0; y < MAP.length; y++) {
                System.out.println("X:" + x + ",Y:" + y);
                setImageContent(x, y);
            }
        }
    }

    private void setImageContent(int x, int y) {
        Terrain t = Terrain.getTerrainFor(MAP[x][y]);
        displayedMap[x][y] = t.getImage();
    }

当城镇构造函数中 y 变为 11，然后转到它所说的 setImagecontent 时

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 11

您交换了数组的尺寸，在数组的一部分中，您使用“X 轴”的大小作为 Y 轴，反之亦然
