Example: Abundant Number Checker in Java

// Abundant Number Checker
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Create a Scanner object to read user input
        Scanner scanner = new Scanner(System.in);

        // Step 2: Prompt the user to enter a number
        System.out.print("Enter a number to check if it's abundant: ");
        int number = scanner.nextInt();

        // Step 3: Initialize sum of proper divisors
        int sumOfDivisors = 0;

        // Step 4: Find proper divisors and sum them
        for (int i = 1; i <= number / 2; i++) {
            if (number % i == 0) {
                sumOfDivisors += i;
            }
        }

        // Step 5: Check if the sum of divisors is greater than the number
        if (sumOfDivisors > number) {
            System.out.println(number + " is an abundant number.");
        } else {
            System.out.println(number + " is not an abundant number.");
        }

        // Step 6: Close the scanner
        scanner.close();
    }
