sum all elements in java code example

Example 1: sum numbers in array java

public class Exercise2 {
public static void main(String[] args) {      
int my_array[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
int sum = 0;

for (int i : my_array)
    sum += i;
System.out.println("The sum is " + sum);
}
}

Example 2: add each element in an array java

import java.util.Arrays;
import java.util.Scanner;
public class SumOfElementsOfAnArray {
   public static void main(String args[]){
      System.out.println("Enter the required size of the array :: ");
      Scanner s = new Scanner(System.in);
      int size = s.nextInt();
      int myArray[] = new int [size];
      int sum = 0;
      System.out.println("Enter the elements of the array one by one ");

      for(int i=0; i<size; i++){
         myArray[i] = s.nextInt();
         sum = sum + myArray[i];
      }
      System.out.println("Elements of the array are: "+Arrays.toString(myArray));
      System.out.println("Sum of the elements of the array ::"+sum);
   }
}
