I've tried at this exercise for 20 minutes now and I can't get it to work! the preview say's it works technically idk

Thanks!

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
do {
  response = console.readLine("Do you understand do while loops?");
  if (response.equalsIgnoreCase("No")) {
  console.printf("Try the video again and come back!");
    }
  } while(response.equalsIgnoreCase("No"));
System.exit(0);

While technically your code works correctly and may function the way you intended to, it isn't exactly doing what the code challenge expected. Code challenges are picky, so you have to do exactly what they say in order to pass.

This is what the code challenge wants:

String response;
do {
  response = console.readLine("Do you understand do while loops?");
} while(response.equalsIgnoreCase("No"));
console.printf("Because you said %s, you passed the test!", response);

This worked! Thank you so much. It sucks that you can't get creative with the example code but I guess what would be impossible to monitor and check each creative way of completing а task.
