Challenge Task 2 Perfecting the Prototype- Don't understand why my code is wrong?

It says "too many loops attempted". Why? Logically, this makes sense to me. While response = "No", prompt the question. Why is this wrong? What is the correct answer?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String prompt = console.readLine("Do you understand do while loops? ");

String response = prompt;

do {
  prompt = console.readLine("Do you understand do while loops? ");
} while(response.equals("No"));

Hey there Nick, looks like you were slightly over-thinking this one and trying to make it more complicated than it had to be, a single String should be good to pass this.

I modified your code to below and it seemed to get through it.

String response;


do {
  response = console.readLine("Do you understand do while loops? ");
} while(response.equals("No"));

I think the trouble was that you had two prompt set to console.readLine(); twice, and the grader was meant to pass "No" once, and your code would ask it to do too, just declaring this at the top would do just fine so that you have the scope to use response out of the loop, while still keeping the control flow of the program running smoothly.

Thanks, hope this helps, feel free to shout if to shout if it doesn't.
