Classes and Interfaces

Classes and Interfaces are fundamental concepts in object-oriented programming (OOP), a programming paradigm that revolves around the creation of objects that contain both data and methods, thereby bundling data and the operations that can be performed on that data. Classes serve as blueprints or templates for creating objects, defining their attributes (data) and behaviors (methods), while interfaces provide a contract or specification that defines the methods that a class must implement. Interfaces play a crucial role in ensuring that classes adhere to a specific set of behaviors, enhancing code maintainability and flexibility.

Understanding Classes

Classes act as blueprints for creating objects, describing their data (attributes) and the actions (methods) that can be performed on that data. Each object created from a class is an instance of that class, possessing its own unique set of attribute values. Methods, on the other hand, define the behavior of objects, allowing them to manipulate their internal data and interact with other objects.

For instance, consider a class named Car. The Car class may have attributes such as make, model, and year, along with methods like drive() and park(). Creating an object of the Car class will result in a specific car with its own make, model, and year, and the ability to drive and park.
