How to find the sum of all the numbers in an array in java?

Java 8Object Oriented ProgrammingProgramming

You can find the sum of all the elements of an array using loops. Create a count variable with initial value 0, iterate the loop till end of the array, add each element to the count.

Example

import java.util.Arrays;
import java.util.Scanner;

public class SumOfAllNumbers {
   public static void main(String args[]) {
      Scanner sc = new Scanner(System.in);
      int count = 0;
      System.out.println("Enter the size of the array that is to be created:: ");
      int size = sc.nextInt();
      int[] myArray = new int[size];
      System.out.println("Enter the elements of the array ::");

      for(int i=0; i<size; i++) {
         myArray[i] = sc.nextInt();
         count = count+myArray[i];
      }
      System.out.println("Array is :: "+Arrays.toString(myArray));
      System.out.println("Sum of all numbers in the array is :: "+count);
   }
}

Output

Enter the size of the array that is to be created::
5
Enter the elements of the array ::
45
56
85
78
99
Array is :: [45, 56, 85, 78, 99]
Sum of all numbers in the array is :: 363
