Write an expression that executes the loop body as long as the user enters a non-negative number. 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."

In the program While loop is used. In the while loop it divides the userNum by 2 in each iteration and prints the value of userNum. The inputs and corresponding outputs are written in the explanation.

Explanation:

In the while loop it divides the userNum by 2 in each iteration and prints the value of userNum.

import java.util.Scanner;  

public class NonNegativeLooper

public static void main (String [] args)

Scanner scnr = new Scanner(System.in);  

//initialize the userNum with 9

int userNum = 9;

//Repeat the loop until the userNum is not negative

while (userNum>=0)

System.out.println(Body);

//Prompt the user to enter the usrNum again

userNum = scnr.nextInt();

System.out.println(Done.);

return;
