    Hello everyone, I have been researching the Singleton Pattern. Since the
    singleton pattern uses a private constructor which in turn reduces
    extendability, if you make the Singleton Polymorphic what sort of
    problems/issues should be considered?

    Also, I see that a singleton needs to be set up with certain data such as
    file name, database URL etc. What issues are involved in this, and how
    would you do this?

    If someone knows about the Singleton pattern please reply. Thanks

    Alicia
