If you use the Singleton pattern out of habit, because it “makes your code more efficient”, you’re premature optimizing

premature optimized code = harder to refactor

Not the implementation.. Now I understand. Actually the patterns are all about concept aren't they? Implementations may vary right? Thanks a lot bro hamdi.. :) Ahah, the concept..

For me, in Java, I implement my Singletons using static methods too (or using IoC). They are still Singletons, just different implementations. As for having multiple implementation, you can actually have that with a Singleton. I can implement a Java Singleton that behave differently. Sort of a combination of Singleton plus Strategy with a good dose of delegation. Just MHO. :) Use Singleton the concept, instead of Singleton the implementation (as in the GoF) book.
