Speed, number of seats, fuel type, etc. It can be instansiated by providing a values to the properties. like Car = etc.Aeroplane = ...

Class is a definition, and object is an implementation/instance of it.Consider an example of a class Vehicle. The properties of vehicles are:The number of wheels, Avg. Speed, number of seats, fuel type, etc. It can be instansiated by providing a values to the properties. like Car = [number of wheels = 4, Avg. Speed=100km/hr, number of seats=5, fuel type=petrol] etc.Aeroplane = [number of wheels = 3, Avg. Speed=700km/hr, number of seats=150, fuel type=petrol] Bicycle = [number of wheels = 2, Avg. Speed=30km/hr, number of seats=1, fuel type=none] Here Vehicle is a class only with the properties' definition of the properties have no absolute values. Whereas Car, Bicycle, Aeroplane are objects of type Vehicle class. read less

Object: Object is the instance of the classes. The object is a bundle of software containing relatedvariables and methods. It contains data and code to operate on those data (functions). Objects are the basic run-time entities of the programming, based on object-orientation. These are the central entities behind the object-oriented programming approach. It may be a person, place, or any data item. It may be any item that the program has to handle. Classes: A class describes a group of objects with similar properties, common behavior, and common relationships to other objects. It is a collection of objects of similar types. It is a user-defined data type that can be used, just like any other basic data type, to declare variables. The class variables are known as objects or instances of a class, which are the central idea of the object-oriented programming approach. read less

A class provides the blueprints for objects. So basically, an object is created from a class. That can be used anywhere as you wish.

Object and any thing exist in the world that is either living or non-living. For e.g. a pen, a book etc. An object is an instance of a class. A class is a group of similar objects. for example Animal is a class and cat, dog, cow etc are the objects of the Animal class.

Class is a prototype for the data and functions you want to create.Object is created as a type of class. For eg car is a class where as honda and hyundai are objects. Without creating objects we cannot access the class directly.

Class is a blue print of objects. Like the blue print of a house, this is like an ammonia blue print (paper) and the actual house that was constructed from the blue print is an object. You can construct as many houses from the same blue print.
