Question

我正在尝试使用从UI指定的X和Y从我的Block对象Array中找到某个块。我一直在使用一个定位器阵列在主阵列旁边制作重复的条目，以便尝试这个。

public Block get(int x, int y) {
            int index = 0;
            index = blocks.indexOf(locator[x][y], true);
            return blocks.get(index);
        }

然后吐出一个java.lang.ArrayIndexOutOfBoundsException：-1 /

看起来它会起作用，但我忽略了什么？

这是错误返回

JAVA：如何在符合特定条件的数组中查找特定对象？
