Bummer! java.lang.RuntimeException: Too many loops attempted! Check your while condition. ()

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean answer;
do {
  response = console.readLine("Do you understand do while loops?");
  answer = (response.equalsIgnoreCase("yes") ||
           response.equalsIgnoreCase("no"));

Almost easier to understand from a beginner than a professional. Thanks!

I believe the right answer for this is : 

   String response;

   do{

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

   }while(response == "No");

   console.printf("Because you said %s, you passed the test!" , response);

You don't need - boolean answer , the quiz asks you to prompt the user with the question - "Do you understand do while loops?" as long as the response is "No!" , So, step-by-step, You create the String variable - response , then create the do-while loop , in the "do" section of the loop , you have to ask the question to the user and then store the answer in the response . We do it with the console.readLine() method , and store the answer with "=" sign like this : 

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

So again, - response is our variable , console.readLine() is the method which prints whatever you right inside it and returns whatever the user types , and we store that (whatever the user types ) with the equal sign - "=" ,

Next, we need the ask that same question again , and again IF the answer (whatever the user types) is - "No" 

 while(response == "No");

It's that simple, "while" the "response" is double equal (which is String comparison for equality) to "No" , everything in the "do"s square brackets will run , again and again as long as the user types "No".

I hope I cleared this up , I'm a beginner myself, so I don't know much of the terms , good luck in your journey :)
