Well I had the same question for a college test, here is the answer:

Explanation:

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);

       System.out.println("How man numbers do you want?: ");

       int n = sc.nextInt();

       int[] a = new int[n];

       System.out.println("Enter " + n + " numbers: ");

       for(int i=0; i<n; i++) {

           a[i] = sc.nextInt();

       }

       System.out.println("The numbers are: ");

       for(int i=0; i<n; i++) {

           System.out.print(a[i] + ", ");

       }

       int sum = 0;

       for(int i=0; i<n/2 ; i++) {

           sum = sum + (a[i] * a[(n-1)-i]);

       }

       System.out.print("\nTheir sum of product is: " + sum);

   }
