Whats wrong with my code??

String response; Boolean negativeResponse; do { response = console.readLine("Do you understand do while loops? "); negativeResponse = response.equalsIgnoreCase("No"); if(negativeResponse) { console.printf("Not a good answer! Try again!"); } } while(negavtiveResponse);

im getting a "illegal start of type error!

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

Hi there! These coding challenges are very picky with what they are looking for. With this code they just want you to prompt the user for a variable called "response", and then continually loop while that variable is No. I changed up the code a little bit and commented out the stuff not needed:

String response;
//Boolean negativeResponse;
do {
  response = console.readLine("Do you understand do while loops?  ");
  //negativeResponse = response.equalsIgnoreCase("No");
 // if(negativeResponse) {
 // console.printf("Not a good answer! Try again!");
  //}
} while(response.equals("No"));

In practice the response.equalsIgnoreCase is good to use, as it will normalize the input. However with this challenge they don't require you to use it.

We don't need a boolean switch here as we can just continually loop the user while response is equal to No. (response.equals("No"))

I hope this helps!
