将力扣字符串形式的二维数组转换成Java二维数组

class MyTest {
    public int[][] toArray(String s) {
        // String s = "[[1,3,1],[1,5,1],[4,2,1]]";
        String[] split = s.split("],\[");
        int[][] ints1 = new int[split.length][];
        for (int i = 0; i < split.length; i++) {
            String replace = split[i].replace("[", "").replace("]", "");
            System.out.println(replace);
            String[] split1 = replace.split(",");
            int[] ints = new int[split1.length];
            for (int j = 0; j < ints.length; j++) {
                ints[j] = Integer.parseInt(split1[j]);
            }
            ints1[i] = ints;
        }
        return ints1;
    }
}
