Do while loop question

I keep getting this question wrong but I'm not really sure what's wrong with my code, I've tried it a bunch of different ways.

Example.java
// I have initialized a java.io.Console for you. It is in a variable named console.
String response = console.readLine("Do you understand do while loops?  ");
boolean invalidAnswer;
do {
  invalidAnswer = (response.equalsIgnoreCase("no"));
  if (invalidAnswer) {
    console.printf("Sorry! Try Again");
  }
} while (invalidAnswer);

Your issue is that you are not doing the prompt in to do while loop.

You need to just declare the new String response outside the loop and then do the prompt in the loop, just like you do with invalidAnswer

String response;
boolean invalidAnswer;
do {
  response = console.readLine("Do you understand do while loops?");
  invalidAnswer = response.equalsIgnoreCase("no");
  if (invalidAnswer) {
    console.printf("Sorry! Try Again");
  }
} while (invalidAnswer);
