Why is my code not working?

I don't get what's wrong with my code? should I add a printf statement even though its not mentioned in the question?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean not;
do {
  response = console.readLine("Do you understand do while loops?");
  not= (response.equals("no"));
  }

Hi there! So for this challenge we do not need to use a boolean. I took a look at the code here and change some stuff up. I commented out the boolean and added the "while" part of the do-while. Here is the fixed up code take a look:

String response;
//boolean not;
do {
  response = console.readLine("Do you understand do while loops?");
//  not= (response.equals("no"));//Commented out the boolean line because we dont need it
  } while(response.equals("No"));//This while checks for the response

Hope this helps, if you have anymore questions let me know! Take care and happy coding

Hi Stephanie,

Michael gave a great answer! Excluding the boolean makes the code much simpler. However, that is actually not your issue.

The problem you are having is simply because you didn't capitalize "no"! Change it to "No" (and add your while argument after the loop like Michael suggested) and you should be good to go.
