WHAT IS THE PURPOSE USING A DRIVED CLASS
In object-oriented programming, a derived class, also known as a subclass or child class, is a class that inherits properties and behavior from another class called the base class, parent class, or superclass. The purpose of using a derived class is to create a specialized version of the base class that adds or modifies its functionality.
Here are some common purposes and benefits of using derived classes:
Code Reusability: Derived classes inherit the attributes and methods of the base class, allowing you to reuse the existing code without duplicating it. This promotes code reusability and helps in maintaining and organizing your codebase.
Specialization: Derived classes can specialize and extend the behavior of the base class by adding new attributes, methods, or overriding existing methods. This allows you to create more specific classes that represent variations or specific types of the base class.
Polymorphism: Derived classes enable polymorphic behavior, where objects of the derived class can be treated as objects of the base class. This allows you to write more flexible code that can work with objects of different types through a common interface.
Inheritance Hierarchy: Derived classes can be organized into an inheritance hierarchy, where multiple levels of derived classes inherit from each other, forming a tree-like structure. This hierarchy helps in organizing and categorizing classes based on their relationships and common characteristics.
Modularity and Separation of Concerns: Using derived classes allows you to separate different concerns and responsibilities into separate classes. This promotes modularity, as each class can focus on a specific aspect of the overall system, leading to more maintainable and extensible code.
Overall, the purpose of using a derived class is to facilitate code reuse, provide specialization, enable polymorphism, and structure your codebase in a logical and modular way.
