Even smart people make financial moves that are downright illogical. Emotions and superstitions have a sneaky way of keeping you from rational financial decisions.

  • Creational - Factory Pattern

    In continuation to my previous post, I am presenting you a sample code that implements Factory Pattern.

    The overview:
     - We are using the Person, Gift and Letter classes as we did in the Abstract Factory Pattern implementation. This is just to show how you can use the same scenario against different patterns.
     - The abstract Person class is the Creator. Gift and Letter are Products.
     - The concrete creator classes are Employee and Colleague. The concrete Product classes are: Email, Postal for Letter; Flowers, Perfume for Gift.
     - The Creator has 2 abstract functions that create Products. the Concrete Classes override them to create different Products.
     - You can create an Array of Concrete objects for the Creator class.

    Takeaways:
     - This pattern is particularly helpful in designing frameworks.
     - The Creator relies on its subclasses to define the factory method to return the appropriate ConcreteProduct.
     - There is no Client class.

    The Creator Class:
