This code sum array in vertical

Code:: public { public static void main(String[ ] args) { int[][] table = { {1,2,3}, {1,2,3}}; int row, column; for (row = 0; row <table.length; row++) { for(column = 0; column<table[ row].length; column++) System.out.print( table[row][column]) ; System.out.println( ); } int[] val = sum1(table); for(int k=0; k<val.length; k++) System.out.print(val[k]+" "); } public static int[] sum1 (int[][] numbers) { int sum[] = new int[numbers[0].length]; /* Change1: set sum[] 's length to (numbers[0].length) */ for (int i = 0; i < numbers[0].length; i++) /*Change 2: change the cond'n */ { / *(k<numbers.length) to (k<numbers[0].length) */ int total = 0; for (int j = 0; j < numbers.length; j++) /*Change 3: change the cond'n (k<numbers[0].length) to (k<numbers.length) */ total += numbers[j][i] ; //Change 4 : replacce [i] each other [j] //System.out.print( total); sum[i]=total; //System.out.println( ); } return sum; } }
