Is there a rule of thumb for when to code a static method vs an instance method?

Question

I\'m learning Java (and OOP) and although it might irrelevant for where I\'m at right now, I was wondering if SO could share some common pitfalls or good design practices.

Answer 1

This thread looks relevant: Method can be made static, but should it? The difference's between C# and Java won't impact its relevance (I think).
