O.T Help sought from Java Programmers

Your student class looks good.

I still don't know the why and what of get and set methods, but I believe this will become apparent when I start fiddling with the array.

Unfortunately, it probably won't become apparent. The assignment you've been given is a terrible way to learn the "why" of OOP, since what you've been told to do is code a procedural style program using objects. But no need to worry about that now
