How is the Builder pattern used

The Builder pattern is a creational design pattern that allows constructing complex objects step by step. This pattern is particularly useful when an object requires several parameters or when the creation process is complicated. It separates the construction of a complex object from its representation, ensuring the same construction process can create different representations.

In the Builder pattern, a builder class is responsible for constructing parts of the object, while the director class orchestrates the building process. This separation enhances code readability and maintainability.
