Did you use console.printf and to write out the formatted string with the response???? Why isn't this working?

Been going crazy trying to figure this out. Everything is layed out perfectly as far as I can see. Please help

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean invalidAnswer;
boolean correctAnswer;
do {
      response = console.readLine("Do you understand do while loops?     ");
      invalidAnswer = (response.equalsIgnoreCase("No"));
      correctAnswer = (response.equalsIgnoreCase("Yes"));
if (invalidAnswer) {
  console.printf("Please enter correct response\n");
}
if (correctAnswer) {
  console.printf("Because you said s%, you passed the test!", response);
}
} while(response.equalsIgnoreCase("No"));

String response;

do{ response = console.readLine("Do you understand do while loops?");

}while(response.equalsIgnoreCase("no"));

console.printf("Bcause you said %s, you passed the test!", response);
