## What are the Perfect Numbers ?

A perfect number is a number whose sum of positive integer factors (divisors without a remainder) excluding itself is equal to itself.

## Code BLock

```

import java.util.Scanner;

public class PerfectNumbers {

    public static void main(String[] args) {

        Scanner input = new Scanner(System.in);

        int i, num, total = 0;

        do {

            System.out.println("Please enter a positive number : ");

            num = input.nextInt();

        }

        while (num <= 0);

        for (i = 1; i < num; i++) {

            if (num % i == 0) {

                total += i;

            }

        }

        if (total == num) System.out.println(num + " is a Perfect Number.");

        else System.out.println(num + " is not a Perfect Number.");

    }

}
