Yep, but public interface is IMHO the methods that could be could called from outside (not the constructor). I know, that everybody tries to interpret every single
word in the assignment. Perhaps Sun wants us to comment all constructors (even the no-arg ones), but I do not see any sense in that.
But I still don't know it of course.
But to be sure, I admit, to add some comments does not hurt. Only "do not provide comments that do not add to the comprehensibility of the code". I have to ask my Mentalo.
