java - 解决数组越界问题

Question

我正在尝试解决 arrayoutofbounds 异常 确切的错误是:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1 Java Result: 1

    public static void emptyBox() {
        int , boxRow, boxColumn, i, j;
        emptyBox = 0;
        Row = 0;
        Column = 0;

        for (i = 0; (i < grid.length) && !(1 == emptyBox); i++) {
            for (j = 0; (i < grid[i].length) && !(1 == emptyBox); j++) {
                if (grid[i][j] == 0) {
                    emptyBox = 0;
                    Row = 0;
                    Column = 0;
                }
            }
        }
    }

    I've tried a few attempts at debugging but no dice.

Answer 1

    for (i = 0; (i < grid.length) && !(1 == emptyBoxFound); i++) {
        for (j = 0; (i < grid[i].length) && !(1 == emptyBoxFound); j++) {

---------------------^

应该是j而不是i

我不知道这是否是唯一的问题，但是......
