Features of OOPs

Features of Object Oriented Programming Language:

-          We have 3 main features, and 8+ basic features.

1.       Encapsulation

2.       Polymorphism

3.       Inheritance

Encapsulation:

Combining the data and the eligible code that acts upon the data into a single unit of an organization so that they are safe from outside interface is called an Encapsulation.

Ø  It hides the non-essential features of an object and provides access privileges only to the essential components.

Ø  It secures data by preventing free-flow of data throughout the application.

Ø  Class represents the basis of Encapsulation, Objects implement Encapsulation.

Inheritance:

Ø  A new entity acquiring the features from the existing entities is called ‘Inheritance’.

Ø  The New Class which inherits the properties is called as ‘child class’, the existing class which is inherited is called as ‘parent class’.

Ø  The Subclass inherits properties from Base class.

Polymorphism:

Ø  ‘Poly’means ‘many’

‘morphism’means ‘forms’

Ø  One interface many forms is the Key concept of polymorphism.

Ø  Polymorphism offers extensibility of code which refers to only one method can be used to get only one functionality but it can be executed to get other functionality.

Ø  This improves flexibility in processing and compactness in application development is achieved.

Ø  With the help of polymorphism, we can generate multiple services of an object with a single method, the behavior of object varies wrt context.
