I can't figure out where to place the console.printf line for Challenge Task 3.

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

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

My guess is inside the if block. Can you post the instructions for the problem?

Finally, using console.printf print out a formatted string that says "Because you said <response>, you passed the test!"

I'm guessing it wants this to print if the user answers YES.

This is what I have come up with and its still sayings its wrong.

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

String response;

boolean isInvalidWord;

do {

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

isInvalidWord = (response.equalsIgnoreCase("No"));

if (response.equalsIgnoreCase("Yes")) {

console.printf("Because you said Yes, you passed the test!");

}

} while(isInvalidWord);

So, it looks like the exercise is wanting you to pass the variable into the string, because that's something nice that can be done with printf. This is what I would do: 

String response; 
do {
     response = console.readLine("Do you understand do while loops?");
     if (response.equalsIgnoreCase("yes")) {
          console.printf("Because you said %s, you passed the test!", response); 
     }
} while (response.equalsIgnoreCase("no"));

That was it. Thank you so much! I forgot about the %s.
