Creational Patterns
•Abstract Factory
–Provide an interface for creating families of related or dependent objects without specifying their concrete classes
•Builder
–Separate the construction of a complex object from its representation so that the same construction process can create different representations
•Factory Method
–Define an interface for creating an object, but let subclasses decide which class to instantiate
•Prototype
–Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype
•Singleton
–Ensures a class only has one instance, and provide a global point of access to it
