Creational Patterns

Creational design patterns deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. They abstract the instantiation process, making a system independent of how its objects are created, composed, and represented.

Patterns in This Category

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