singleton class vs static class

static class 를 사용하려 하다 문득 singleton과의 차이점이 궁금하여 찾아보았다. 아래 4가지가 내가 여러 포스트에서 본 것을 정리해둔 것 같다.

1. Singleton objects are stored in Heap, but static objects are stored in stack.
2. We can clone (if the designer did not disallow it) the singleton object, but we can not clone the static class object .
3. Singleton classes follow the OOP (object oriented principles), static classes do not.
4. We can implement an interface with a Singleton class, but a class’s static methods (or e.g. a C# static class) cannot.
