我需要计算用户输入只有0的行数，比如

Test 1
0 0 0
1 2 3
2 2 1

Test 2
1 2 3
0 0 0
0 0 0

Rows with only 0 values: 3

这是读取矩阵的代码

final int rows = 3, cols = 3;

        Scanner input = new Scanner(System.in);
        System.out.println("Number of tests");

        int n = input.nextInt();

        int test[][][] = new int[n][rows][cols];

        for (int i = 0; i < n; i++) {
            System.out.println("Test "+(i+1));
            for (int j = 0; j < rows; j++) {
                for (int k = 0; k < cols; k++) {
                    test[i][j][k] = input.nextInt();
                }
            }
        }
