Java Java Basics Perfecting the Prototype Looping until the value passes

The loop should continue running as long as the response is No.

I've messed with this so long I don't know what is my work and what are suggestions from others. The Preview says it's fine, but Bummer ticker says be sure it keeps looping while the answer is No. I can't see what I'm doing wrong. Please help. Thanks.

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.

String response = ""; boolean isNo; do { console.readLine("Do you understand do while loops? "); isNo = (response.equalsIgnoreCase("No")); if (isNo) { console.printf("Try again. \n"); } } while(isNo);

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?  ");

hello, he's asking you loop when u get No response by using do while loop and you can achieve that like this code.

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

Hi Lee Preslan , 4th line means if the condition response equals to No continue Looping and it will keep asking until the condition is false

while(response=="No");
