I gave this a bit of thought before. I felt in some situations, static methods and instances are preferred. For example, if you want to synchronize a query method. Or in some situations where overriding is rare, i.e., java.util.Calendar.

Static methods are evil for many reasons including philosophical (they're not OO) and practical (you can't override their behavior). You should use a Singleton class with non-static methods. Struts' RequestUtils class is a good example of why you should never use static methods. Developers want to override their behavior but can't because everything is static.
