Java Java Basics Perfecting the Prototype Looping until the value passes

What is wrong? When I compile this code in the workspace it works fine. I copy and paste and it wont work in quiz.

I created a file in workspaces called If.java and wrote this code: import java.io.Console;

public class If {

    public static void main(String[] args) {
        Console console = System.console();
      String noun;
      boolean isInvalidWord;
      do {
        noun = console.readLine("Do you understand do while loops?  ");
        isInvalidWord = (noun.equalsIgnoreCase("no"));
      if (isInvalidWord) {
        console.printf("That language is not allowed.  Try again.  \n\n");
        }
      } while(isInvalidWord);


    }

}

// It compiles and runs in workspaces but it won't pass in the quiz //

Hey Steven,

Are you writing this code in your own text editor? For this challenge, you do not need to set-up the basics of a Java program. You can begin with the response variable.

I've tried to simply the program below with comments.

// Initialize response
String response;

// Begin loop
do {
    // Assign response variable to prompt
    response = console.readLine("Do you understand do while loops?");
} while(response.equalsIgnoreCase("No")); // Prompt user while response equals, "No."

// Provide a success message to user
console.printf("Because you said %s, you passed the test!", response);
