The Problem

One of the goals of object-oriented design is to delegate responsibility among different objects. This kine of partitioning is good since it encourages Encapsulation and Delegation.

 

The Solution

Factory Method is a creational pattern. This pattern helps to model an interface for creating an object which at creation time can let its subclasses decide which class to instantiate.
