Factory Pattern

In space and astronautical engineering, the Factory Pattern is a design pattern that allows the creation of objects without specifying the exact class of object that will be created. It provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created. This pattern is useful in situations where the exact type of object needed is determined at runtime, or when a class wants to delegate responsibility for object creation to one or more helper classes.
