import java.util.Scanner;

public class SumOfElementsArray {
 public static void main(String[] args) {
  int i, n, sum = 0;
  Scanner scan = new Scanner(System.in);
  System.out.print("How many elements do u want to add ?\t");
  n = scan.nextInt();
  int array[] = new int[n];
  for (i = 0; i < n; i++) {
   System.out.print("\nEnter number" + (i + 1));
   array[i] = scan.nextInt();
  }
  scan.close();
  for (i = 0; i < n; i++) {
   sum = sum + array[i];
  }
  System.out.print("\nThe sum of " + n + " numbers is " + sum);
