Example: Greatest of Two Numbers using if-else in Java

// Greatest of Two Numbers using if-else
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 the first number
        System.out.print("Enter the first number: ");
        int num1 = scanner.nextInt();

        // Step 3: Prompt the user to enter the second number
        System.out.print("Enter the second number: ");
        int num2 = scanner.nextInt();

        // Step 4: Compare the two numbers using an if-else statement
        if (num1 > num2) {
            System.out.println(num1 + " is the greatest number.");
        } else {
            System.out.println(num2 + " is the greatest number.");
        }

        // Step 5: Close the scanner to prevent resource leaks
        scanner.close();
    }
