Answer / tarangini
oops concepts are Encapsulation, inheritance, abstractio
and polymorphism.
Encapsulation: Buildingup of the data and methods as a
single unit is called encapsulation. It isolates the
members of one class from the members of another class, so
we can declare same variable in both the classes.
best example for encapsulation is: A Class
Inheritance: Producing the new classes from already
existing class is called inheritance. The newly produced
class contains the features of old class and it has its own
features.
the use of inheritance is reusability.
Abstraction: Hiding unnecessary data from the user is
called Abstraction.
Polymorphism: Poly means many. Morphism means forms.
If same object perfrom different tasks is called
polymorphism.
