A Guide on Object-Oriented Programming: Pros and Cons

Nowadays, all of the people around us talk about object-oriented programming.  Also, we often heard “this programming language is object-oriented.” But do you know what does it mean? It’s great if you already know; otherwise, you can take help from this guide to complete your assignments. So let’s start our today’s session.

Before moving ahead let’s know what we are going to discuss here:

  • What Is Object-Oriented Programming?
  • Concepts and Principles of OOP
  • Advantages of Object-Oriented Programming
  • Disadvantages of Object-Oriented Programming

What Is Object-Oriented Programming?

Object-oriented programming is the language of computers that organize software around data rather than function or logic. Also, it contains data in the form of different fields. Thus these fields are properties or attributes. Besides this, it includes several instructions in the form of procedures known as methods.

Why is OOP Important?

Below mentioned are different purposes of using OOP:

  • The sole purpose is to implement real-world entities like polymorphism, inheritance, hiding, and so on.
  • Ensure that no code can access the particular data instead of a function, by binding functions and data
  • Refers to the language that utilizes the object in programming
  • Defines a variety of languages that are capable of creating instances
  • Useful for determining the type of languages

In object-oriented programming, concepts like classes and objects come into existence. That is why some famous languages that use these real-world entities are: Python, Java, C++, and so on. So let’s know more about these concepts and principles.

Concepts and Principles of OOP

There are different concepts of OOP. The brief discussion about these concepts is as follows:


Polymorphism refers to the capability of object-oriented programming language. This reference efficiently differentiates between different entities. This concept is mainly useful in Java in two forms: Overloading and Overriding in Java.


The main purpose of abstraction is to cover complexity. Also, it demonstrates elemental information according to the requirement. Too understand it better, suppose you want to use a computer but do not want to get information about internal workings. Thus a similar case happens in the coding when an individual seeks to use abstract interfaces or classes by hiding internal implementations.

Thus abstraction as object-oriented programming allows users to hide underlying data complexities. Also, there is a scope to avoid repetitive code so that programmer can create different types of objects.


This compact is an approach that allows programmers to protect data in classes. Thus it safeguards all the internal content from class like a wrapper. That is why, through its help, a programmer can deploy encapsulation. The main aim of encapsulation is to restrict direct use to the fields of the class.

 As it allows programmers to re-use the functionalities without explaining security, it works a powerful tool that saves time. Also, it will enable programmers to create code that can call specific data from any database.


It helps create the child class that effectively inherits the methods of the parent class. Thus a child class can easily override the functions associated with parent class, which are not very essential. Also, it is useful to improve code reusability and multilevel inheritance.

Advantages of Object-Oriented Programming

Some of the primary advantages of object-oriented programming are as follows:

  • The main reason behind the OOP approach is to eliminate the limitations of procedural programming methods as it is the best approach for software development.
  • OOP provides a feature of the reusability of classes. Thus it is easy to use previous classes. Also, this reusability saves time and eliminates the need for coding again and again.
  • It allows parallel development of classes. That is why it is the quickest way to develop programs.
  • As it uses abstract principles, it is one of the secure development approaches. Here data is hidden, and any external function cannot access this data. Thus it allows programmers to extract usable data without disturbing others’ security.
  • The coding in object-oriented programming is easy to maintain as there is a centralized coding base. Also, it is easy to keep all data accessible while updating it.

Disadvantages of Object-Oriented Programming

Although object-oriented programming is useful for several purposes, it has some disadvantages. Lets’ explore them in detail.

  • If the relationship among different classes becomes artificial, it causes difficulty in the development.
  • Programs developed by OOP are large. Also, it requires additional resources for the implementation that creates overhead runtime issues.
  • The concepts of OOP are a bit more complicated than procedural programming languages. Thus it is more complex for programmers to understand its working.
  • As it requires specialized skills for understanding program logic, it is difficult to debug the code.
  • Increased lines of code have significant effects on the processing time. It is because instructions added in the program need more time for execution.

So object-oriented programming is one of the main topics in a programming language that you must know. To become a programmer in the future, you must have complete knowledge of this topic.
