Question

4.2.2 Basic while loop with user input. JAVA

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


Note: These activities may test code with different test values. This activity will perform three tests, with user input of 9, 5, 2, -1, then with user input of 0, -17, then with user input of 0 1 0 -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.

Please use my Template

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.");
