The factory design pattern is a popular pattern that can be used to create objects. It is a creational pattern (GOF) and provides a standard and elegant way to create instances of classes.

Inspired by Ruby ’s polymorphic ability to create different objects based on context, Venkat proposes an implementation of the factory method pattern by using Java’s default keyword.

The Factory design pattern is a simplified form of the Builder pattern. In essence, you would want to use the Builder design pattern when you need to create a complex object in a step by step manner.
