System.out.println

Today I am working on Basic while loop for my App Development (Java) class, with user input and I have no idea who to write the code string they need

Here is the code

import java.util.Scanner;

public class NonNegativeLooper {

public static void main (String [] args) {

Scanner scnr = new Scanner(System.in);

int userNum = 0;

while (/* Your solution goes here */) { // here is where my code goes

System.out.println(“Body”);

userNum = scnr.nextInt();

}

System.out.println(“Done.”);

return;

}

please help
