Mike,

Way to go! Just a few hints to get you on track:

     String response;
     do {
       response = console.printf("Do you understand do while loops?"); //readLine(" ... ")?
     } while (response == "No"); //using == test if the String objects are equal and not the Strings. Use .equals()

      //Don't assign this to response. You just need to print out the message.
      //Remember the format : console.printf("something something blah %s", variable); 
      response = console.printf("Because you said resonse, you passed the test!");

Hope this helps.

Regards,

Chris

Here you dont need to create a new object of the Console class because the console object is already defined for you and you can use console.readLine() to store an Input in a String. You dont need to create console

Console console = System.console();

instead you use this

String inputFromUser = console.readLine("Do you understabnd the do/while Loop?  ");

If you want a do/while-loop that is asking the user, whether he understands ít. You can do it this way

do{
String inputFromUser = console.readLine("Do you understabnd the do/while Loop?  ");
 // the users input is stored in the inputFromUser variable 
// when the user types "no" the loop repeats,  when  "yes" the loop is over
//The user can input No (uppercased) and the loop is also over
}while(inputFromUser .equalsIgnoreCase("no"));

I hope it helps a little
