What am i doing wrong?

I have no clue what I am doing wrong

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

 }
   }while(wrongAnswer);

Hello mate,

You correctly declare String response; outside of the do-while statement, so that it can be accessed by the statement's conditional expression. Checking for the condition that causes execution of the do-while statement to end, from within its body, is unnecessary.

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

Hope this helps

If there's a boolean in it does it need to be told that the it shouldn't accept "No" both inside the brackets and outside?
