ENCAPSULATION

Encapsulation when we talking about this its simple idea we can remind capsules which we using to take as medicine.mainly here what they doing is protecting the things inside from the outside world.This will keep contain together also it will protect the contents inside.

In OOP it will take attributes & behaviors & it will bundle together in same unit as class.after encapsulate your class we cant access to this class without having particular behaviors.It will help to control outside access & keep security of data.

Here we will open inputs & outputs to outside but without using input you cant change inside details.this is simple example for Encapsulation.

ABSTRACTION

Abstraction considering their important characteristics and ignore all specific instance. Abstraction not  having specific instance it will represent common facts. Abstract classes are something in the middle between classes and interfaces. They can define ordinary methods and abstract methods.

Eg:  inside class room we can have students.when we going to implement classes here we using one class called student.Which will contain common instance like student name,student id, student registration number & etc.but we never going to create class under each & every student name n his details .

This abstract classes will not contain individual specific  data of particular object.

Polymorphism

In Object-oriented programming,polymorphism(from the Greek meaning "having multiple forms") is the characteristic of being able to assign a different meaning or usage to something in different contexts-specifically,to allow an entity such as a variable,a function or an abject to have more than one form.There are several different kinds of polymorphism.
