What am I doing wrong?

What exactly am I doing wrong here?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean answer;
do {
response = console.readLine("Do you understand do while loops?");
answer = (response.equalsIgnoreCase("No"));
  if (answer) {
    console.printf("Sorry mate. ");
  } while (answer);
}

I think your missing an instance of console

Console console = System.console();

You're close. You just need to rearrange your code a little bit, and eliminate some of the code.

Task 1: Step 1: First, you declare your String variable.

Step 2: Prompt the user for a response to the question: "Do. you understand do while loops?", and save the response in the variable you declared in step 1.

Task 2: Create a "do while" loop to keep asking the user the same question as long as the answer is "no".

Here's an example:

String variable;

do { response = console.readLine("Question"); } while (response.equalsIgnoreCase("Answer"));

You don't need to Boolean variable, or the if statement. I hope that helps you.
