Using console.printf to print out a formatted string

I am supposed to use console.printf to print out the response "Because you said <response>, you passed the test!"

I typed this code for one of the challenges and it came back with this response: "Did you use console.printf and to write out the formatted string with the response?"

Is there something missing or some better way I should write this?

Oops, here is the code:

String response;
boolean tryAgain;
boolean youPassed;
do {
  response = console.readLine("Do you understand do while loops?");
  tryAgain = response.equalsIgnoreCase("No");
  youPassed = response.equalsIgnoreCase("<response>");
  if (youPassed) {
    console.printf("Because you said <response>, you passed the test!");
  }
} while (response.equalsIgnoreCase("no") || response.equalsIgnoreCase("<response>"));

Personally I would write something like this just to avoid declaring extra variables:

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

But the reason your code isn't passing the last part of the challenge is because you aren't utilizing the printf function.

String response;
boolean tryAgain;
// Removed boolean variable 'youPassed' since we aren't using it.
do {
  response = console.readLine("Do you understand do while loops?");
  tryAgain = response.equalsIgnoreCase("No");
  if (!tryAgain) {  //The '!' symbol means 'NOT'
    // If NOT equal to value of 'tryAgain', execute if's code-block. 
    console.printf("Because you said %s, you passed the test!", response);
    /* We are using printf function here which means 'print formatted.' 
     * So we want to display the response within our string.
     * The %s means string, and we fill it with variable 'response' declared after our string.
     */
  }
} while (response.equalsIgnoreCase("no")); 
    //Remove OR clause because we only want it to continue when the reply is "no."
    //Removed: || response.equalsIgnoreCase("<response>")

Good job on the challenges so far and happy coding! Feel free to ask for help whenever you need it!
