In factory pattern, we create objects without exposing the creation logic to the client and the client uses the same common interface to create a new type of object. Abstract factory design pattern provides an approach to code for interface rather than implementation.

The factory method pattern is a class creational pattern and is also known as a virtual constructor. I will not say anything more. It is related to object creation. A factory defines as a function which should generate the desired object based on some params (the usual usage is a string parameter which defines the desired class). In this series.

This is done by creating objects by calling a factory method—either. Making a factory is as trivial as: But there remains coupling where instances are actually created. In our example we are going to use an interface and some concrete classes. The factory method disallows the use of constructor & users to use static methods instead of using constructor.
