STOP No check again summing column by column. If you want sum of all elements then doesn't make sense to get by column. I have given example also in code, you can check.

How do you want to sum by the column, if the 2D array has data such as the sample array I've written?

This will give the sum of 1st column import java.util.Scanner; public class Summing2Darrayelements { public static void main(String[] args) { Scanner input= new Scanner(System.in); // 2.1 // fourth way int [][] TwoDArray= new int [2][2]; // initializing 2D array using for loop System.out.println("Please enter the elements :"); for(int row=0; row< TwoDArray.length; row++) { for(int col=0; col< TwoDArray[row].length; col++) { TwoDArray[row][col]= input.nextInt(); }} // summing array elements int total=0; int col=0; for(int row=0; row<2; row++) { total+= TwoDArray[row][col]; } System.out.println("the total sum of array element is: "+total); } }

STOP Do this int total=0; for(int row=0; row< TwoDArray.length; row++) { total = 0; for(int col = 0; col < TwoDArray[row].length; col++) { total += TwoDArray[col][row]; } System.out.println("Column wise sum of array element is: " + total); }
