Please tell me what I am doing wrong.

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

  }
while (response);

Hi William. Couple of things. While (response) is not valid. response is not a boolean. You need to compare something. Since you want to run the loop while response is No something like (response == "No")should work.

Also inside you loop response is not a valid statement. It is just the value of the answer the user typed. It will not re-prompt the user for an answer. you need to have 

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

inside your loop. While leaving the first statement will work if you want your code to be DRYer then just declare the response variable outside the loop (String response;) since you are prompting the user inside the loop and it will always prompt the user before checking the while condition.

Hope this helps william and keep at it!
