Builder Design Pattern

Builder is a creative design pattern that allows you to build complex objects step by step. The pattern allows you to produce different types and representations of an object using the same building code.

Imagine a complex object that requires laborious step-by-step initialization of many nested objects and fields. This initialization code is usually buried inside a monster constructor with many parameters. Or even worse: scattered throughout the client code.

The Builder pattern suggests that you extract the object construction code out of its own class and move it to separate objects called builders.

Lets look up the code examples I wrote as below.
