More a C++ person than a Java person, but ...

I don't think "a.super ()" is valid (or at least relevant). Parameter "a" is of
type "A" and class  "A" doesn't have a specified parent class.

I assume the parameter "a" will contain a reference to the associated "A" class
item. Why not then use "a.test()"?

This is very rude. I'm sure the capabilities of the people on this list range
between beginner and guru. Where do you sit on this range?
