Dec 22, 2015 at 20:01	comment	added	Robert Snyder		Emz is spot on in defining it. I like to consider as a small form of documentation too. If I see private only it means I could have a getter or setter on that field. If i see private final I know that is either used explicitly by this class, or that it has a getter only. (less things for me to look up if needed, or when I come back to it later)

Dec 22, 2015 at 18:56	comment	added	Adam Hodgson		Thanks very much for your answer, it has definitely been very helpful! I would like to ask why you have chosen to declare StudentData[][] as both private and final? It was my understanding that since private already prevents overriding adding the final keyword is considered redundant.
