What Is the Use of Object Oriented Programming?


Heather Bennett

Object Oriented Programming (OOP) is a programming paradigm that provides a way of structuring and organizing code. It is widely used in software development due to its numerous benefits and advantages. In this article, we will explore the uses and advantages of Object Oriented Programming.


One of the key features of Object Oriented Programming is encapsulation. Encapsulation allows us to group related data and functions together into objects. By encapsulating data within objects, we can control access to it and prevent direct manipulation.

Encapsulation provides several benefits:

  • Data hiding: Encapsulation allows us to hide the internal details of an object and only expose what is necessary. This prevents other parts of the program from directly accessing or modifying internal data.
  • Code organization: With encapsulation, code becomes more organized by grouping related data and functions together. This improves code readability and maintainability.
  • Code reusability: Objects can be reused across different parts of a program or even in different programs, promoting code reusability.


Inheritance is another fundamental concept in Object Oriented Programming. It allows us to create new classes based on existing classes, inheriting their properties and behaviors. The new class, known as a subclass or derived class, can extend or modify the functionality inherited from its parent class.

Inheritance provides several benefits:

  • Code reuse: Inheritance allows us to reuse existing code by inheriting from a base class. This promotes code reusability and reduces redundant code.
  • Modularity: Inheritance enables us to create a hierarchy of classes, with each class representing a specific level of abstraction.

    This promotes modularity and allows for easier maintenance and extension of code.

  • Polymorphism: Polymorphism, another feature of Object Oriented Programming, is closely related to inheritance. It allows objects of different types to be treated as instances of a common base class. This enables code to be written in a more generic and flexible manner.


Polymorphism is the ability of an object to take on many forms. In Object Oriented Programming, polymorphism allows objects of different classes to be treated as instances of a common base class.

Polymorphism provides several benefits:

  • Code flexibility: Polymorphism allows for writing code that can work with objects of different types, providing increased flexibility and adaptability.
  • Simplified code: By using polymorphism, we can write more generic code that can handle multiple scenarios without the need for repetitive coding.
  • Easier maintenance: Polymorphic code tends to be easier to maintain as changes made in one place can have an impact on multiple objects or classes.


In conclusion, Object Oriented Programming provides several benefits and advantages. Encapsulation helps in organizing and controlling access to data and functions, while inheritance promotes code reuse and modularity.

Polymorphism enables writing flexible and generic code. By leveraging these features, developers can create more organized, maintainable, and reusable code.

If you are new to Object Oriented Programming, it is recommended to explore these concepts further and practice implementing them in your projects. With time and experience, you will fully appreciate the power and usefulness of Object Oriented Programming.
