Im not sure what is wrong, can anyone help :) ?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

String response;
do {
response = console.readLine("do you understand do while loops?");
} while (response.equalsIgnoringCase("no"));

Do you get an errors when this is run? It would be helpful to see any errors you are getting, or to hear an explanation of the issue you're having.

It's best to always provide this details alongside questions.

This might just be your capitalisation. This works:

// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
do {
  response = console.readLine("Do you understand do while loops?");
} while (response.equals("No"));

To add to what Steve said, even though the question is not requiring it, you had written response.equalsIgnoringCase(), but it is "response.equalsIgnoreCase("whatever string")"

Well spotted - yes; the function isn't quite right too.

String response; 
boolean invalidWord;

do {
 response = console.readLine("Do you understand while loops?");
 invalidWord = (response.equalsIgnoreCase("no"));
 if (invalidWord) {
  console.printf("Response not valid. Please try again...\n");
    } 
 } while (invalidWord);

Hope it helps :)
