Example: Largest of Three Numbers using Logical AND in Java

// Largest of Three Numbers using Logical AND
import java.util.Scanner;

// Main class containing the entry point of the program
public class Main {
    public static void main(String[] args) {
        // Step 1: Declare variables to store the three numbers
        int num1, num2, num3;

        // Step 2: Create a Scanner object to get user input
        Scanner scanner = new Scanner(System.in);

        // Step 3: Prompt the user to enter the three numbers
        System.out.print("Enter the first number: ");
        num1 = scanner.nextInt();

        System.out.print("Enter the second number: ");
        num2 = scanner.nextInt();

        System.out.print("Enter the third number: ");
        num3 = scanner.nextInt();

        // Step 4: Determine the largest number using if-else if-else with logical AND
        if (num1 >= num2 && num1 >= num3) {
            System.out.println("The largest number is: " + num1);
        } else if (num2 >= num1 && num2 >= num3) {
            System.out.println("The largest number is: " + num2);
        } else {
            // If neither num1 nor num2 is the largest, num3 must be
            System.out.println("The largest number is: " + num3);
        }

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