Answer 1

STOP

Change your last loops

Answer 2

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.

Answer 3

STOP

{1, 4},
{5, 6}

Tell me what should be output in this case?

Answer 4

The code works, it sums all the element. What is the problem?

Answer 5

No read the full qustionIpang

Answer 6

Okay, sorry ...
So for this array example, what is the expected output?

{
{1, 2, 3},
(4, 5, 6)
}

Answer 7

Ipang i didnt understand what you mean

Answer 8

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

Answer 9

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);

}
}

Answer 10

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);
}
