Module 2 - Lab - Countdown

Objective

Instructions:

Create a new Java file named Countdown.java. This is the class where you'll implement the countdown logic.
In the Countdown class, define three methods: doWhileCountdown(), whileCountdown(), and forCountdown(). Each method will implement the countdown using a different loop structure.
Implement the doWhileCountdown() method using a do-while loop, whileCountdown() method using a while loop, and forCountdown() method using a for loop. Each method will count down from 10 to 1 and then print "Blastoff".
Now, create another Java file named CountdownApp.java. This will contain your main method, and you'll use it to create an instance of the Countdown class and call each of its methods.

Here's the Java code that meets the above requirements:

CountdownApp.java code starter:

public class CountdownApp {
    public static void main(String[] args) {
        Countdown countdown = new Countdown();

        // Run the do-while countdown
        countdown.doWhileCountdown();

        // Run the while countdown
        countdown.whileCountdown();

        // Run the for countdown
        countdown.forCountdown();
    }
}

Expected Output:
