Sums Arrays

Hello, I need to sum the evrey column in arrays, like exmple:

I have multidimensional arrays, like this: int[][] row ={{1, 2, 1}, {8, 1, 54}};

i need to get in the result the sum: 9, 3, 55.

I use in for loop, but i get only 9..

this is my loop:

int perTotal = 0;

     for(int i =0; i<row.length; i++){
         perTotal += row[i][0];

} System.out.println(perTotal); }

how can I get the sum of evrey column? Thank you for help :)

int perTotal=0; for(int i=0;i<row.length;i++){ perTotal += row[i][0]; } you used" row1" in conditional and "row" in body
