Java Java Basics Perfecting the Prototype Looping until the value passes

I can't figure out final step.

If the answer to response is 'yes' I want it to print out 'because you said yes, you passed the test'.

I've gone through various options but I can't get anything to work.

Can anyone help please?

// 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("Do you understand do while loops?");
} while(answer);

This is the working code:

String response;
do {
 response  = console.readLine("Dou understand do while loops?");
} while(response.equalsIgnoreCase("No"));

console.printf("Because you said %s, You passed!", response);

you have few mistakes. u dont need to declare another variable called "answer" and u dont need an if statment because u use a while loop, as u know while loops used to loop until certain condition are met and for this case the loop will continue until ther user says no. in the "do" code block u just need to assign response to store the users input. then u want to keep prompt the user as long as he says No and u do it as i did, and finally if he didnt say No, u print the user's response.
