The book mentions on p. 336 that the "private void printMenu (Iterator iterator)" method does not need to be changed. I'm running Eclipse IDE Version: 2022-03 (4.23.0) and the interpreter will complain with a warning that " Iterator is a raw type. References to generic type Iterator should be parameterized", as well as throw an error on the "MenuItem menuItem = iterator.next();" line, stating " Type mismatch: cannot convert from Object to MenuItem".
Changing "private void printMenu (Iterator iterator)" to "private void printMenu (Iterator iterator)" remove both the warning an error and solves the problem
