How to Get Sum of Elements of an Array using Java

import java.util.Scanner;

class ArraySum
{
    public static void main(String args[])
    {
        Scanner in = new Scanner(System. in );
        System.out.println("Enter the number of elements in array:");
        int elements = ( in .nextInt());
        int[] array = new int[10];
        int sum = 0;
        System.out.println("Enter the elements:");
        for (int i = 0; i < elements; i++)
        {
            array[i] = in .nextInt();
        }
        for (int num: array)
        {
            sum = sum + num;
        }
        System.out.println("Sum of array elements is: " + sum);
    }
