What is class in programming

The main ideas behind Java’s Object-Oriented Programming, OOP concepts include abstraction, encapsulation, inheritance and polymorphism .

C++ What is OOP? OOP stands for Object-Oriented Programming . Procedural programming is about writing procedures or functions that perform operations on the data, while object-oriented programming is about creating objects that contain both data and functions.

Classes are required in OOPs because: It provides template for creating objects, which can bind code into data . It has definitions of methods and data. It supports inheritance property of Object Oriented Programming and hence can maintain class hierarchy.

a class describes the contents of the objects that belong to it : it describes an aggregate of data fields (called instance variables), and defines the operations (called methods). object: an object is an element (or instance) of a class; objects have the behaviors of their class.
