In Object-Oriented Programming (OOP), a class is a blueprint for creating objects. It encapsulates data for the object and methods to manipulate that data. Classes are fundamental to OOP as they provide a way to structure and organize code in a modular and reusable manner1.
Key Principles of a Class
Attributes and Methods: A class defines attributes (data members) and methods (functions) that operate on the data. For example, a Car class might have attributes like color, model, and speed, and methods like accelerate() and brake()2.
Encapsulation: This principle ensures that the data (attributes) of a class is hidden from other classes and can only be accessed through the methods of the class. This promotes data integrity and security2.
Inheritance: Classes can inherit attributes and methods from other classes, promoting code reuse and reducing redundancy. For example, a SportsCar class might inherit from a Car class and add additional features1.
Polymorphism: This allows methods to do different things based on the object it is acting upon. For example, a method draw() might behave differently for Circle, Square, and Triangle classes2.
