JAVA: Write an expression that executes the loop body as long as the user enters a non-negative number. Note: These activities may test code with different test values. This activity will perform three tests, with userNum initially 9 and user input of 5, 2, -1, then with userNum initially 0 and user input of -17, then with userNum initially -1. See How to Use zyBooks. Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report "Program end never reached." The system doesn't print the test case that caused the reported message.

Code with message:

import java.util.Scanner;

public class NonNegativeLooper { public static void main (String [] args) { Scanner scnr = new Scanner(System.in); int userNum = 0;

userNum = 9; while (/* Your solution goes here */) { System.out.println("Body"); userNum = scnr.nextInt(); } System.out.println("Done.");

return; } }

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:

20 10 5 2 1 

Code with question:

import java.util.Scanner;

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

userNum = 20;

/* Your solution goes here */

System.out.println("");

return; } }
