A class is a set of objects that share a common

The type of an object is known as its Class

Abstract description of an object

Object Oriented approach:

Emphasis on data

Programs are organized into classes and objects and the functionalities are embedded into methods of a class.

Data can be hidden and cannot be accessed by external sources.

New data and functions can be easily added whenever necessary

Hi,

Class contains method where you can write code in it.

Interface contains method where you cannot write code..

You cannot create an instance for an Interface. But for a class you can create an instance..

THanks,
