**JAVA** Write an expression that executes the loop while the user enters a number greater than or equal to 0. 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.

Please make sure the loop is *not* infinite.

import java.util.Scanner;

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

userNum = scnr.nextInt();

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