What is an Object ?

   Let us now look deep into what are objects. If we consider the real world we can find many objects around us, cars, Dogs, Human, etc. All these objects have states and behavior. If we consider Dog, then its state is – name, breed, color and behavior is-barking, wagging, running etc.

Ø  If you compare the software object with real world object, they have very similar characteristics.

Ø  Software objects also have a state and behavior. A software object’s state is stored in fields and behavior is shown via methods.

Ø  So in software development, methods operate on the internal state of an object & object to object communication is done via methods.
