Java Program to find sum of array elements

Program

import java.util.Scanner;
public class SumOfArrayElements {
  public static void main(String[] args) {
    System.out.println("Enter the required size of the array: ");
    Scanner reader = new Scanner(System.in);
    int size = reader.nextInt();
    Integer inputArray[] = new Integer[size];
    System.out.println("Enter the elements of the array: ");
    for (int i = 0; i < size; i++) {
      inputArray[i] = reader.nextInt();
    }
    double sum = 0;
    double average = 0;
    for (int i = 0; i < size; i++) {
      sum = sum + inputArray[i];
    }
    System.out.println("Sum of given numbers is: " + sum);
  }
}
