Java Java Basics Perfecting the Prototype Looping until the value passes

In spite of no error , why does compiler is not validating my code ?

I always stuck with this type of problem. Is there any shorter way to get out when i got this ?

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?");
boolean isResponse;
do {
  isResponse = (response.equalsIgnoreCase("No")||response.equalsIgnoreCase("Yes"));
  if (isResponse){
  console.printf("Try again!");
  }
}while(isResponse);

Hi abhishek kumar,

You seem to have more code than what is required for this challenge, task two simply asks for the following.

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.

All the task want's you to do is re-use the same code from task one but instead re-assign it while ensuring the string equals No, see the below.

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

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

Happy coding!

thanks....
