You can find numerous reasons for using a Singleton over a Static class. But there must surely be some situations where it is better to use a static class before a Singleton. What are they?

Answers

You can use static class when:

1) all its methods are utilities (nice example - class Math)

2) you don t want to deal with preserving your instance from garbage collector (in applets), but I would better use singleton there

3) you are absolutely sure that it wouldn t become stateful in the future and you are sure that you will always need only one instance of that class

If you are using singleton and in one moment you realize that you need several instances then your singleton easily can be transformed to multitone, but you ll have a problem with static class
