Java Java Basics Perfecting the Prototype Looping until the value passes

Java Basics; Do While Loops; console.printf(3/3 "<response>");

I no longer understand what is being asked of me in this Bummer response. I have made many different versions of this code, many times including this one with no compiler errors but still get a try again prompt. This task has turned me into The Crypt Keeper; HELP!

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean respponse;
        do {
         response= console.readLine("Do you understand do while loops?");
             response.equals("No");
       console.printf("Bummer");
       respponse= (response.equals("<response>")) ||
                 (response.equals("<>"));
    if (response.equals(respponse))  {
       console.printf("Because you said <response>, you passed the test!");  
    System.exit(0);}
    }while(response.equals("No"));
       console.printf("Because you said <response>, you passed the test!");

Hi Frank,

You have almost the complete answer contained within your code already. There are more variables than what you really need at this point. Here is what you should keep (with *** to point it out):

// I have initialized a java.io.Console for you. It is in a variable named console.
***String response;***
boolean respponse;
        ***do {
         response= console.readLine("Do you understand do while loops?");***
             response.equals("No");
       console.printf("Bummer");
       respponse= (response.equals("<response>")) ||
                 (response.equals("<>"));
    if (response.equals(respponse))  {
       console.printf("Because you said <response>, you passed the test!");  
    System.exit(0);}
    ***}while(response.equals("No"));
       console.printf("Because you said <response>, you passed the test!");***

Then you are down to the following code:

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

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

Now, you only need to make a change to the printf statement. Since printf involves string conversion, I would suggest replacing <response> with %s and specifying that the response variable requires a conversion. Something like this:

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

So your finished code should look something like this:

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

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

Cheers!
