To find the sum of elements of an array.
  1. create an empty variable. ( sum)
  2. Initialize it with 0 in a loop.
  3. Traverse through each element (or get each element from the user) add each element to sum.
  4. Print sum.

Simply so, how do you add numbers in an array?

To find sum of all elements, iterate through each element and add the current element to the sum. Which is run a loop from 0 to n. The loop structure should look like for(i=0; i<n; i++). Inside the loop add the current array element to sum i.e. sum = sum + arr[i] or even you can do sum += arr[i].

Also, how do you add all the numbers in an array Java? Program:

  1. public class SumOfArray {
  2. public static void main(String[] args) {
  3. //Initialize array.
  4. int [] arr = new int [] {1, 2, 3, 4, 5};
  5. int sum = 0;
  6. //Loop through the array to calculate sum of elements.
  7. for (int i = 0; i < arr. length; i++) {
  8. sum = sum + arr[i];
