Nice general way to sort nulls to the bottom, regardless?

I'm writing some custom Comparators, and I'd like them to push null items to the bottom of the list, regardless of whether I'm sorting ascending or descending. What's a good strategy or pattern for approaching this? Offhand: - Simply write separate ascending and descending comparators, sharing code where possible - Delegate null handling to another class, either by throwing an NPE or by calling it explicitly - Include an ascending flag and put conditional logic in it to navigate around the nulls - Wrap regular comparators in a null-handling class Any other strategies? I'd like to hear about any experiences with different approaches, and any pitfalls for the various strategies.
