Java Java Basics Perfecting the Prototype Looping until the value passes

Not sure how to do this exercise.

How do I continually prompt the user in a do while loop, and the loop should continue running as long as the response is No.

import java.util.Scanner;
class Test{

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        boolean flag = true;
        while (flag) { 
            String response = input.next();
            if (response.toLowerCase().equals("yes")) { 
                flag = false;
            }
            // Rest of Loop Goes Here
        }
    }
}

could also do "while (response.equals("no"))"

Thanks Ryan. I already finished the exercise just a minute ago though I used this: <code> String response; boolean wrongAnswer; do { response = console.readLine("Do you understand do while loops?"); wrongAnswer = (response.equals("No")); if (wrongAnswer) { console.printf("Incorrect reply"); } } while(wrongAnswer); </code>
