The client may be either another object or the actual client that calls the main() method of the application, initiates the Builder and Director class.

The Builder represents the complex object that needs to be built in terms of simpler objects and types.

The constructor in the Director class receives a Builder object as a parameter from the Client

The Builder class should be an abstract class so that it can provide the Client with an interface for all concrete Builders.

So if the Builder class is an abstract class,we can add new types of complex objects by only defining the structure and reusing the logic for the actual construction process.

The Client is the only one that needs to know about the new types, the Director needing to know which methods of the Builder to call.
