Code Challenge: Looping until the value passed. Where is my mistake?

Hey everyone. I am a little stuumped by part 3 of this coding challenge.

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

My code is:

// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean invalidResponse;

do {
response = console.readLine("Do you understand do while loops?");
invalidResponse = (response.equalsIgnoreCase("No"));
}while(invalidResponse);
console.printf("Because you said <response>, you passed the test!");

And the error I receive is: Bummer! Did you use console.printf and to write out the formatted string with the response?

As far as I can see, I have done this correctly. Am I missing something ridiculously obvious?

Thanks guys :-)

Hi,

I just completed this challenge and here is my working code:

    // I have initialized a java.io.Console for you. It is in a variable named console.
    String response = console.readLine("Do you understand do while loops? ");

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

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

If we compare this to your code, there are few differences. Your way of doing is fine but there are few errors in your code

    // I have initialized a java.io.Console for you. It is in a variable named console. 
    String response; 
    boolean invalidResponse;

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

    console.printf("Because you said <response>, you passed the test!");

First, there are parenthesis around the (response.equalsIgnoreCase("No"));

Second, you are printing string <response> instead of the actual string-value.
