You can ditch the first two variables (abc & noun). You'll want to switch the noun variable name in you do-while to response. Then you'll want to add the while portion at the end of the do {}.

Example:

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

That way the user can be prompted "Do you understand do while loops? " and their response will be read into the 'response' variable. which can then be checked in the 'while' comparison argument. If the user responds "no" the DO portion will execute again.

Let me know if you have questions!
