try this public class array01 { public static int sumColumn (int[] [] matrix, int column) { int sum=0; for (int i=0; i<matrix.length;i++){ sum=sum+matrix[i][column]; } return sum; } public static void main(String[] args) { int matrixa[][] ={{1,2,3,4},{2,6,8,9},{8,6,9,8}}; System.out.println(sumColumn(matrixa,1)); } }
