<http://lmgtfy.com/?q=java+elevator+simulator>

In general terms, Patricia Shanahan, Ph.D., has put together some advice on how to approach any programming problem:
<http://home.earthlink.net/~patricia_shanahan/beginner.html>

I'll only add that it is a good idea to create a model of how elevators operate, or at least of how an idealized elevator would operate.  This model should be quite independent of any programming language.  Rather, it would be a precise description of the operations, commands and behaviors of the system.  "Nouns and verbs analysis", I call it.  What things do stuff, and what stuff do they do?

Now as for needing an algorithm that "need not be .. complex but I need some fancy algorithm", that's rather a contradiction.  "Fancy" is pretty much equivalent to "complex".

You say "SCAN, LOOK, FCFS, etc." as if that makes any sense to anyone.  Define your behaviors completely - if you want to keep things simple, define fewer behaviors.  In other words, there shouldn't be any "etc."  FIgure out what a "SCAN" is (if you're supporting that behavior).  It's more than a label; it's a to-be-defined set of very specific changes to your system state.
