We say 'Society','Forest' etc....
Does Society exist? No.Only Human beings are there.Human is real ,but not the Society.
Does Forest exists anywhere? No.Only Trees,Plants are there....There are thousands of trees in this earth.How can we call those trees in a single 'Collective' name-the 'Forest'....
Abstraction simplifies the view of something which is un-comprehensive...
When No subscribers are there for buying 'News Magazine',There is no purpose of publishing 'Magazines'.
Subscribers are needed to 'realise' (Implement) the 'abstraction'.
'Interface' is burnt or skeleton Car.You cannt use it directly.You have to 'implement' all its real parts to use ,drive...
'Abstract' class is somehow 'breakdown' car.One cannt use fully ,but it can be repaired'(Extended) to use later for driving....
Great Explanations
