Java Java Basics Perfecting the Prototype Looping until the value passes

Can someone explain to me why the code isn't working?

The compiler says I'm attempting too many loops at the same time.

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

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

String response = question;
boolean wrong;
do {
  question = console.readLine("Do you understand do while loops?:  ");
  wrong = response.equalsIgnoreCase("No");
  if (wrong) {
    console.printf("That's too bad");
    }
} while(wrong);

It's been a while since I did any Java but I suspect it's something to do with the way your boolean variable is declared.

You don't really need a lot of the code here, including the boolean. I suspect you only need to do the prompting code once, inside the do while loop. and assign it to a variable called Response.

Like this synrax.

// I have initialized a java.io.Console for you. It is in a variable named console.

String response;

do {
  response = console.readLine(" [prompt the user here]  ");

} while ( [expression that looks for the value of response variable] );

Thanks Jonathan. I might have to go back and review Booleans, it's seems I have a shallow understanding of the concept.
