In object-oriented programming (OOP), a class is a fundamental concept that serves as a blueprint for creating objects. A class defines a set of properties (attributes) and methods (functions) that are common to all objects of that type. It encapsulates data for the object and methods to manipulate that data.
Definition and Structure
A class in Java is a user-defined data type that consists of data members and member functions. It represents the set of properties or methods that are common to all objects of one type. For example, consider a class Car. All cars share common properties like wheels, speed limit, and mileage. Here, Car is the class, and wheels, speed limits, and mileage are its properties1.
