Question

**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.");
}
}

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 (userNum >= 0) {
            System.out.println("Body");
            userNum = scnr.nextInt();
        }
        System.out.println("Done.");
    }
