oops concepts are mainly 3
1.encapsulation
2.inheritance
3.polymorphism
1 :- encapsulation refers to binding the data in a single
class the data present inside the encapsulation is secured.
abstraction comes under encapsulaton.
real time example:-if you get fever you will take the
medicine to cure.the medicine is the capsule in which the
powder is present.the powder is a mixture of several
chemicals as in the same way all the classes are mixed and
only the output(object) you will see as if a capsule.
2 :- inheritance is nothing but extending the class from
parent to the child
real time example:- the prime minister of india
(late)mr.jawaharlal nehru and his daughter indira gandhi
and her son rajiv gandhi and his wife sonia gandhi.
3 :- polymorphism refers to which it does many things
real time example:- consider the electric power which does
many things .
