Stuck on Challenge Task 2 of Looping Until value passes

Hi guys , I've been stuck on task 2 of the Looping Until the Value Passes Challenge for a few days.Lines 2 and 4 of my code seems to work but I'm getting errors from line 5 onwards.

I'd be very grateful if you could take a look. Thanks.

String questionAsString = console.readLine("Do you understand do while loops? ");

String response = console.readLine("No.");

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

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

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