Find the perfect number between two numbers

I’m new to Java, and in order to practice I found a task on the Internet:

"Find all the perfect numbers between the two numbers you enter."

By the way – a perfect number is a natural number equal to the sum of all its own divisors. So I got to work and ran into such a problem that when I enter two numbers.

For example: 1 100, I get the correct answer in the console: 6,28. But if the first number is, for example, 100 and the second is 500 I get this output to the console: 6,28,496,, while I should get only 496. That is, for some reason, the minimum value does not shorten the search for a perfect number.

Here’s where I ended up:

import java.util.Scanner;

public class IsPerfect {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int min = in.nextInt();
        int max = in.nextInt();

        System.out.println(min +" to "+max+" perfect numbers:");
        for (min = 1; min <= max; min++) {
            int sum = 0;
            for (int e = 1; e < min; e++) {
                if ((min % e) == 0) {
                    sum += e;
                }
            }

            if (sum == min) {
                System.out.print(sum+ ",");
            }
        }
    }
}

If anyone has any advice on how to fix this error, I would sincerely appreciate it.

>Solution :

You are assigning the minimum value to 1, no matter what the user enters. Change your outer for loop to start from the minimum value the user enters:

import java.util.Scanner;

public class IsPerfect {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int min = in.nextInt();
        int max = in.nextInt();

        System.out.println(min +" to "+max+" perfect numbers:");
        for (; min <= max; min++) {
            int sum = 0;
            for (int e = 1; e < min; e++) {
                if ((min % e) == 0) {
                    sum += e;
                }
            }

            if (sum == min) {
                System.out.print(sum+ ",");
            }
        }
    }
}
