Prototype - creation pattern

The purpose of the Prototype Pattern is to offer the option of creating multiple classes based on one class: a prototype. This pattern can be created when we want a large number of objects of the same type or when we need to create a collection of almost the same object.

Here's an example implementation of a prototype in ABAP:

The zcl_car class is the class that creates an abstract definition of new cars:

CLASS zcl_car DEFINITION ABSTRACT.    PUBLIC SECTION.      METHODS:        clone ABSTRACT          IMPORTING                    iv_color         TYPE string          RETURNING VALUE(ro_object) TYPE REF TO zcl_car.  ENDCLASS.                    "zcl_car_data DEFINITION 

In the following class, is the definition of every prototype with the implementation of how a car should be built:
