What are the difference between a static class and a singleton class?
Following are the differences between a static class and a singleton class.
A static class can not be a top level class and can not implement interfaces where a singleton class can.
All members of a static class are static but for a Singleton class it is not a requirement.
A static class get initialized when it is loaded so it can not be lazily loaded where a singleton class can be lazily loaded.
A static class object is stored in stack whereas singlton class object is stored in heap memory space.
