I dont understand what this question is asking me to do regarding formatted string.

My Code:

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

The question is asking for me to enter a formatted string that includes the console.readLine value entered for response. I'm confused how i would create another string that includes the value entered for a previously declared string.

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean noResponse;
do {
  response = console.readLine("Do you understand do while loops?");
  noResponse = (response.equalsIgnoreCase("no"));
  if (noResponse) {
    console.printf("Try again.");
  }
} while (noResponse);
String closing = console.printf("Because you said %s, you passed the test!");

I solved the problem myself by looking back at old code:

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

but i hate doing that, it feels like cheating.

Way to go! Everyone looks at old code so don't worry about it. I like to keep snippets of code and other notes for reference.

I just feel like its cheating when ive followed the video examples, written out the code he has then i go and just copy it in the exercises. i feel like that doesnt help me fully grasp the concepts. is this something i should not worry about?

In short, don't worry about it. It's hard to remember all of the methods and their signatures at first. After more experience looking at lots of code it becomes second nature to construct the statements correctly. Manually repeating proper code is the first step. Using the lessons to synthesize new code come next. Then finally coding from a blank slate.
