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." The system doesn't print the test case that caused the reported message.

           while (Num>=0) {

               System.out.println("enter a another number");

               Num = in.nextInt();

           }

Explanation:

The complete java code prompting a user to enter a number until a negative number is entered is given below:

import java.util.Scanner;

public class num6 {

public static void main (String [] args) {

Scanner in = new Scanner(System.in);

System.out.println("enter a number");

int Num = in.nextInt();

while (Num>=0) {

System.out.println("enter a another number");

Num = in.nextInt();

}

System.out.println("Done.");

return;

}

}
