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: userNum = AD.nextInt(): for(userNum = 3: userNum > = 0: userNum --) { if(userNum > = 1) { System.out.println(userNum): }else { System.out.println("Blastoff!"): } } return: }
