Creational patterns provide various object creation mechanisms, which increase flexibility and reuse of existing code. Some creational patterns are:
Factory Method- Provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created.
Abstract Factory- Let's you provive families of related objects without specifying their concrete classes.
Builder- Let's you construct complex objects step by step. The pattern allows you to produce different types and representations of an object using the same construction code.
Prototype- Let's you copy existing objects without making your code dependent on their classes.
Singleton- Let's you ensure that a class has only one instance, while providing a global access point to this instance.
