what examples of static classes vs. singleton

Question

I read the answer about static vs singelton, however, i specifically look for concrete examples of when should i use a static class instead of a singelton. As it seems at the moment, singelton should always be used.

Thanks.

The singleton is a pattern. A pattern is supposed to be a solution for a problem you might experience. — Myrtle, Jun 03 '13 at 08:45

I suggest you to read the book "Design patterns - Elements of Reusable Object-Oriented Software" by Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides (http://en.wikipedia.org/wiki/Design_Patterns).

Among the differences, a singleton can be be lazily constructed, requiring no memory or resources until needed.

But a static need not be constructed at all. – weston Jun 03 '13 at 08:54
@weston it does. There are static constructors for example. – Myrtle Jun 03 '13 at 09:03
@Aphelion Sure, but 1. they don't construct anything unless you call `new` statements inside them and 2. they are lazy (c# at least), being called on the first time the class is used, which is precisely their argument for using singleton over static. – weston Jun 03 '13 at 09:11
