In java, Write a while loop that prints userNum divided by 2 (integer division) until reaching 1. Follow each number by a space. Example output for userNum = 20:

public class HelloWorld{

public static void main (String []args) {

int userNum = 20;

while (userNum!=1) {

userNum = userNum/2;

System. out. print (userNum+" ");

}

}

}

Explanation:

Create the main function and declare the variable userNum with value.

then, use a while loop and it run until the userNum not equal to one when it become equal to 1 the while loop terminate.

Inside the loop, divide the userNum by 2 and then assign to userNum and this process continue until condition true.

for example:

userNum = 20

userNum = 20/2=10

then, 10/2=5

5/2=1

after that condition false. and while loop terminate.
