Write code that prints: userNum ... 2 1 Blastoff! Your code should contain a for loop. Print a newline after each number and after Blastoff!. Ex: userNum = 3 outputs:

3 2 1 Blastoff! -------------------------- 

import java.util.Scanner;

public class CountdownRocket { public static void main (String [] args) { int userNum = 0; int i = 0;

userNum = 3;
