OBJECTS ENCAPSULATE STATE AND BEHAVIOUR

Can you clearly make out what this statement –“objects encapsulate state and behaviour”- is trying to convey? No? Same problem was with me also but when I read it for the first, go deep and you will find easy. Well let’s first discuss a term called encapsulation, after which the above statement will become clear to you. We shall also talk about linked term ”abstraction” to understand it more clearly.

What is abstraction?

Abstraction is a concept of simplifying a real world concept into its essential elements.

    Abstraction refers to the act of representing essential feature without including the background details or explanations.

To understand abstraction let us take an example. Suppose you are driving a car.You only know the essential features to drive a car i.e. gear handling, steering handling,use of clutch, brakes,accelerator etc. But while driving do you get into internal details of car like wiring, petrol tank, motor workingetc. ? You just change the gear or apply the brakes etc. What is happening inside is hidden from you. That what abstraction is, where you only know the essential things to drive a car without including the background details or explanations.
