This Web service returns information specific to a particular user based upon input from that user on a Web page. It is like a question/answer, where the answer given in a form text field must match the answer provided by the user a...
I've heard people advise that one should always use the Iterator pattern to control loops rather than throwing an exception (which is how it's done in Python iterators) or using the Sentinel pattern, whereby a special, sentinel value (often null) is returned to indicate the end of the iteration.

I can't use just an expressio...
