If everything is an object , Cant we declare every object as Shouldn't we make a class with all static members is its just expected to be executed as a standalone program with just one thread. Moreover Lets assume that there is no runtime Polymorphism required and there is no need for serialization ? Is this Polymorphism ? When are static and instance methods resolved ? During compile time or Runtime ? Which of the following is not the difference between Singleton and Static class ( Class with static members only ) ?
