Generalization

Learn about generalization and how it enhances reusability, extensibility, and maintainability through inheritance and abstraction.

Generalization is a fundamental concept in object-oriented design (OOD) that involves extracting common properties and behaviors from multiple classes and consolidating them into a single parent class. This allows subclasses to inherit shared attributes and methods while having the flexibility to specialize further. Abstracting common behaviors into a parent class simplifies code maintenance, enhances reusability, and supports easier code extension.

Importance of generalization

  • Code reusability: Reduces duplication by allowing subclasses to reuse code from the parent class.

  • Extensibility: New classes can easily be added by extending the parent class, without altering existing code.

  • Polymorphism: Parent class references can point to child class objects, promoting more general and adaptable code that can easily work with new subclasses in the future.

  • Maintainability: Changes to shared behavior must only be ...
