Design Patterns in 1 minute: Builder #1
Classification: Creational
Builder is a design pattern aimed at enabling the creation of complex objects in a simplified and structured way.
The Problem
Imagine a class with multiple properties. Consequently, the constructors of this class will have N arguments.
Creating these objects at runtime can become a challenging task.
Additionally, evolving these classes is also complex, as every new property added affects all constructors.
How can we solve this problem?
The Solution
The Builder pattern suggests extracting the responsibility of constructing this class into another specialized class, hence the name Builder.
This specialized class should provide methods that prepare the object creation process step by step and, finally, offer a method that constructs our class.
