We have the following oops concepts like
1.Abtsrction
2.Encapsulation
3.Inheritance
4.Polymorphism

Abstraction:

hiding unnecessary data from the users and making the
application as user friendly then it is called as
abstrcation

ex:Any mail account the user is simply filling the form and
he don't know ho it is developed.

Encapsulation:

Wrapping the data and code as a single unit is called as
encapsulation.

ex:Capsule is the best real time example for it.In it we
will have two types of drugs combined as single capsule.

Inheritance :
Acquiring the properties from one class(base class or parent
class)to another class(derived class or child class)is
called as inheritance.

Ex:Inventing laptop from desktop.

Polymorphism:

Single entity behaving in different forms is called as
polymorphism

ex:Mouse is for click the buttons and dragging the bars or
placing the pointer in a particular place.
