while condition

It keeps saying I have too many loops being run and I have no idea why

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.equalsIgnoreCase("no")){
  console.readLine(response);
}

Since your loop only checks the response given the first time, if the first answer is "no", the loop will run forever.

You need to make the body of the loop reassign the value of response. And instead of using the previous response as the prompt, you should probably ask the question again.
