I can't see where I'm going wrong :\

I've tried everything but am unable to see what I am doing wrong with regards to this question.

"Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop."

My attempt is attached:

Would someone please shine some light on my predicament and help me progress to the end of the course?

Thank you! : )

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

Hi there! Parts of your code are correct. In fact, if I were to selectively delete parts of it, it would pass. Take a look and see how close you are/were :smiley:

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

I declare my string. Then I ask the user for an answer. While the answer is equal to "no" (ignoring the case), I ask them again. Hope this helps! :sparkles:

You don't need the if statement or line 9. You just need to state what this program will do (repeat it self) while the response is "no".

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

Thank you very much for your replies Jennifer and Justin, it really did help me a lot! Seems that I was way over complicating things. :smiley:
