Design Patterns – Builder Pattern

A Factory Design Pattern is used when the entire object can be easily created and object is not very complex. Whereas Builder Pattern is used when the construction process of a complete object is very complex.

Builder pattern aims to “Separate the construction of a complex object from its representation so that the same construction process can create different representations .” It is used to construct a complex object step by step and the final step will return the object.18 Eki 2021

The Builder pattern suggests that you extract the object construction code out of its own class and move it to separate objects called builders . The Builder pattern lets you construct complex objects step by step. The Builder doesn’t allow other objects to access the product while it’s being built.
