📘 Step by Step Learning

Study this program carefully to understand the logic, output, and explanation in a structured way.

Information & Algorithm

Given Input:

Enter an integer: 12

Expected Output:

Divisors of 12 are:
1 2 3 4 6 12

Program Code

import java.util.Scanner;

public class Divisors {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter an integer: ");
        int num = sc.nextInt();

        System.out.println("Divisors of " + num + " are:");

        for (int i = 1; i <= num; i++) {
            if (num % i == 0) {
                System.out.print(i + " ");
            }
        }

        sc.close();
    }
}

Explanation

Logic Used

Start from 1 up to the given number.
If the number is divisible by i (i.e., num % i == 0),
→ then i is a divisor.

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
