In Object-Oriented Programming (OOP), a class is a blueprint or template that defines the structure and behavior of objects. It encapsulates data attributes (properties) and methods (functions) that operate on the data. A class serves as a template for creating instances of objects, representing real-world entities, concepts, or entities in a software system.
On the other hand, an object is an instance of a class. It is a concrete realization of the attributes and behaviors defined by the class. Objects have a state, which is determined by the values of their attributes, and behavior, which is defined by the methods associated with the class. Objects interact with each other through method calls, forming the basis for modularity and reusability in OOP.
For example, consider a class "Car" that defines the properties (attributes) like "model," "color," and "speed," as well as methods like "start," "accelerate," and "stop." Instances or objects of the "Car" class could represent specific cars, each with its unique attributes and behavior. This separation of concerns into classes and objects allows for a more organized and modular approach to software design, promoting code reuse and maintainability.
