Builder Pattern

Question 1

builder pattern

Answer 1

used to build objects. Sometimes, the objects we create can be complex, made up of several sub-objects or require an elaborate construction process. The exercise of creating complex types can be simplified by using the builder pattern. A composite or an aggregate object is what a builder generally builds.

Question 2

-builder pattern advantage

Answer 2

a builder pattern encapsulates or hides the process of building a complex object and separates the representation of the object and its construction. The separation allows us to construct different representations using the same construction process

Question 3

The class diagram consists of

Answer 3

Builder
Concrete Builder
Director
Product

Question 4

The builder pattern might seem similar to the abstract factory pattern but one difference is that

Answer 4

the builder pattern creates an object step by step whereas the abstract factory pattern returns the object in one go.

Question 5

Builder class

Answer 5

contains a method for each component that can be part of the final product. }

These methods are selectively overridden by concrete builders depending on if the builders will be including that part in the final product variant that they are responsible for building.

Question 6

Director class

Answer 6

contains The process or algorithm required to construct the product

Question 7

Skipping the Director

Answer 7

You may find the builder pattern being used without the director. The client can directly instantiate the builder and invoke the required methods to get a product for itself.
