Answer 1

I personally hate dealing with special null cases everywhere in my comparators so i was looking for a cleaner soluation and finally found google collections. Their Ordering is just awesome. They support compound comparators, offer to sort nulls to the top and to the end and allow to run certain functions before comparing. Writing comparators has never been so easy. You should give it a try.
