While Loop Task 2.

I believe I have all the syntax correct, but it keeps prompting me with an incorrect answer? I am completely lost, I feel like I am not reading the task correctly..

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

The logic of the code is a bit off.

You store the question in the variable response, and then you check if the response variable contains the word no. That check will always be false because you are storing the question in that variable, not the word no. Then you prompt for input but you don't actually store or use the result of that input anywhere.

If you move the code around a bit like this:

String response;
boolean wrongAnswer;
do { 
  response = console.readLine("Do you understand while loops?");
  wrongAnswer = response.equalsIgnoreCase("no");
}while(wrongAnswer);

Then it will work, as in this case the input is stored in the response variable and then compared to no afterwards.

Thank you so much! This really helped me, I felt like I wasn't understanding something about the question right... Again, thank you!
