Objects are the basic key to understand object-oriented programming. Programming objects are just like real-world objects. Look around, you'll see many objects. Your car, mobile phone, desk, laptop, pet dog, and DVD player are all objects.
All objects have two characteristics: properties and methods.
A mobile has properties (color, screen size, height, and weight) and methods (make calls, send SMSs, receive calls, and transfer files).
A car has properties (color, height, gearbox, wheels, engine, brakes, and steering) and methods (start engine, steer, change gear, apply brake, stop, and crash).

So, an object, in terms of programming, can have properties (variables in any programming language) and methods (functions in any programming language).Hence, we can define an object as "an entity or a thing that has some properties and methods associated with it. An object can be individually selected and manipulated...
