如何使用多维数组得到java中每一行的总和？

int[][] array = {
    {1, 2, 3},
    {4, 5, 6},
    {7, 8, 9}
};

int[] rowSums = new int[array.length];

for (int i = 0; i < array.length; i++) {
    int sum = 0;
    for (int j = 0; j < array[i].length; j++) {
        sum += array[i][j];
    }
    rowSums[i] = sum;
}

for (int i = 0; i < rowSums.length; i++) {
    System.out.println("第 " + (i + 1) + " 行的总和为：" + rowSums[i]);
}
