How can I make my first Java code work? I'm only level 2 but I want to make a countdown from 5 to 1 with an exclamation.

My code is supposed to be a countdown from 5 to 1. When it reaches 1, I want it to output "Liftoff!". https://code.sololearn.com/c5seZyTZgZ6P/?ref=app

// Java code to count down to 1 and then show the word "Liftoff!" public class Liftoff { public static void main(String[] args) { // size = 12 int x = 5; while(x > 0) { if (x == 1) { System.out.println("Liftoff!"); }else{ System.out.println(x); } x--; } } }

Considerations: you forgot the closing bracket of the if and for loop

//optimized import java.util.Scanner; public class Liftoff { public static void main(String[] args) { Scanner sc=new Scanner(System.in); int x =sc.nextInt(); while(x > 0) { System.out.println(x==1?"Liftoff!" :x); x--; } } }

I found that in order to have an output with the number 1 and with the liftoff exclamation, I also needed to change the while statement to while(x >= 0). Thanks for your feedback!
