[Java] Class Hierarchy Design

I've never heard of LISP before... lol. I guess you did my homework without any trouble. <_<

B > your knowledge.

LISP is basically, uh, old programming language. Some says you can compare it to Latin, though it may seem like Greek to others. Very easy to recognize due to its insane amount of parentheses. (((((((((())))))))))

And ugh, I try to avoid doing hw for others At least I hope you understood what I tried to explain and such.
