Answer 1

No offence, duffymo, but my teacher said that a
mutator returning a boolean indicating success or
failure is a terribly bad idea. That was also one of
the reasons for my question.No offence taken.
paulcw's comment about following the Bean standard and having mutators return void is probably as good a reason to follow this advice as any. There's no reason to assume that doing a simple set operation on a private data member will require additional feedback for the client.
But even this rule has its exceptions within Java itself.
If you look at the java.sql package and the Statement class, you'll see that the executeUpdate() method runs a SQL command that modifies a database and returns the number of affected rows. Would your professor say this is a terrible idea? In this case I'd say no.
That's one problem with academics teaching things like programming. I don't know what your professor's background is, but it's important to talk about the exceptions to rules when you dole them out (and there are always exceptions). Know the rules, know the reasons behind them, know when and why to break them.
Find out if your professor went straight through to get their Ph.D. without ever working for a living. Find out if they've ever coded anything other than academic assignments. That will tell you a lot about the instruction you're getting.
