Which design pattern will you use to create a complex object?
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.
How do I know which design pattern to use?
To use design patterns effectively you need to know the context in which each one works best. This context is : Participants — Classes involved. Quality attributes — usability, modifiability, reliability, performance.
What is the difference between Builder design pattern and composite design pattern?
Composite creates Parent - Child relations between your objects while Builder is used to create group of objects of predefined types.
Why do we use builder pattern?
The builder pattern is a design pattern designed to provide a flexible solution to various object creation problems in object-oriented programming. The intent of the Builder design pattern is to separate the construction of a complex object from its representation. It is one of the Gang of Four design patterns.
