Just What Is OOP?

Procedural languages emphasise on functions and processes, whereas Object Oriented Programming (OOP) is structured around objects and classes.

When it comes to managing large, organised projects, programmers prefer to concentrate on the objects related to a problem rather than the solutions, which is why Object-Oriented Programming (OOP) has emerged as the most commonly used approach in modern programming.

Fully comprehending the definition, requirements and benefits of Object-Oriented Programming (OOP) is crucial to fully grasp its potential. So, to determine whether OOP is appropriate for your projects, let us delve deeper.

Name the three key principles of OOP.


Code reuse can be achieved through the use of Inheritance between classes, where one class can inherit properties or methods of another through a “child” class relationship. Object-Oriented Programming facilitates such inheritance for code reuse purposes.

The number of subclasses permitted for a class is arbitrary, and whether or not it is suitable for a given project depends on the specifics of the project.

Other languages, such as JavaScript, use a similar process known as Prototyping, which can serve as a basis for subsequent development.


Encapsulation is dependent on abstractions in order to function effectively. Abstraction entails that all information pertinent to a class is kept together. Objects should only provide data that is relevant to other objects, while keeping any information only applicable to itself concealed.

To prevent other programmers from potentially causing errors when utilising your code and classes, it is critical to prohibit them from manipulating the internal elements of an object. While it is permissible to have variables and methods at an object level that can alter the state of an object, it is essential to shield such modifications from other objects that interact with the original object.

With Encapsulation, it is possible to specify which variables and methods within a class are public, protected, and private, which facilitates the realisation of Abstraction. This provides developers with the ability to control data accessibility and modifiability by external entities.


Polymorphism pertains to the change in an object’s behaviour based on its class. It is typically observed in objects that share a common inheritance tree, with the methods of the child class taking precedence over those of the parent class.

A frequently asked question about computer programming is, “What exactly is an Object-Oriented Language?”

Thanks to the widespread integration of objects and classes, Object-Oriented Programming (OOP) projects can now be developed using a variety of programming languages. Some commonly utilised examples include:

  • C++
  • C#
  • Java
  • ECMAScript-derived languages, such as JavaScript
  • Python
  • Ruby

A Comprehensive Explanation of Object-Oriented Programming

Now that we have established a practical understanding of the underlying principles of Object-Oriented Programming (OOP), it is time to explore an illustration. For this, we will be using a C# example. Let us start by defining the members of the Animal class.

This code will produce an error since the function Object() { [native code] } for Animal has no linked access modifier and is consequently assumed to be private. Thus, it cannot be invoked from the class Program. Encapsulation may be employed to fix this problem.

To apply polymorphism, we must make a modification. We must employ the C# keywords ‘virtual’ and ‘override’ to create the notion of method overloading. Additionally, we must change the ‘_age’ variable’s descriptor from ‘private’ to ‘protected’ to permit access from our derived classes.

The Advantages of OOP Techniques in Software Development

Before deciding on the use of a programming paradigm, such as OOP, it is vital to understand its pros and cons. While there is no denying the potential benefits of OOP, which can be essential in streamlining a project, improper use can result in unnecessary complexity.

Financial Advantages of Out-of-Pocket Expenses

  • Problem Partitioning: Object-oriented programming aids developers in dividing intricate tasks into more manageable components, making the development process more streamlined.
  • In addition to the previous point, OOP projects may have their functionality improved by incorporating more classes and methods.
  • OOP enables developers to model problems as objects in their code in order to create a more effective problem map.
  • Encouraging the adoption of strong encapsulation practices can enhance project safety and security, and also aid programming teams in working more efficiently while mitigating the risk of errors.
  • Inheritance can facilitate the reuse of code across multiple classes, saving time on development and lowering the possibility of errors. Libraries are also useful in allowing developers to leverage their work on other projects.

Issues with Out-of-Pocket Payments

  • Performance:

    Object-oriented programming (OOP) typically necessitates a greater number of objects for a project to function when compared to procedural approaches, resulting in larger program sizes and longer execution times.
  • Preparation Required:

    It is important to have a clear understanding of the architecture’s design at the start of OOP development to avoid challenges and the need to reorganize code later on.


Object-oriented programming (OOP) is a valuable approach to software development as it offers developers a dependable framework for structuring and organizing their work. Additionally, OOP is well-suited to allow projects to evolve naturally, which is crucial in today’s market where frequent updates are necessary.
