Advantages and Disadvantages of Object-Oriented Programming (OOP)

Some of the most popular and useful programming languages are based – at least partially – on an object-oriented approach, thus proving the value of this programming methodology. We are talking about the languages like C++ and Java, so it’s fair to assume that the concept of object-oriented programming is very important for the overall niche.

But it is really so superior? 

The shortest answer is: No. Just like all other programming languages out there, this one also comes with both pros and cons. It’s a very interesting and important topic, so let’s discuss the basics of object-oriented programming (OOP) and its advantages and disadvantages. 

What Is OOP?

Before we dig deeper into the concept, let’s first explain the basics of OOP. By definition, OOP represents a programming paradigm based on the concept of objects that can contain data and code. 

Jake Gardner, an IT specialist who can offer programming assignment help, says that the program is based on several concepts: 

  • Objects: These are the main run-time segments that exchange information once the program is launched. 
  • Classes: Similar types of objects are called classes. 
  • Inheritance: This is the precondition of reusability in OOP because inheritance allows a certain type of object to acquire the characteristics of an object belonging to a different class.  
  • Polymorphism: It’s a feature that represents an object’s nature to perform multiple operations. 
  • Data abstraction and encapsulation: This enables the system to reveal critical features without the need to provide any additional details. 

Pros of OOP

OOP is a popular programming method for various reasons, but we will highlight the most important characteristics here.

1. Highly productive software development

OOP is a modular type of programming, which means that it distinguishes between different duties and allows objects to be extended. In other words, objects can be given fresh attributes and become reusable.

2. Easier software maintenance

Other programming systems require major structural changes in case of updates or new features. On the other side, OOP makes it possible to focus on individual modules only and simplify software maintenance. 

3. Speedy development

Entire libraries of OOP objects are already available for wider usage, so it’s easy to create and develop codes just by using the existing solution.

4. Low-cost development

Speed is not the only benefit of object reuse. Namely, developer units can save time and money by reusing and enhancing the existing objects. 

5. Improve quality through detailed testing

Programmers who save time with reused objects can dedicate more time to testing and quality assurance. This means that the final product is almost always high-quality and bug-proof.

Cons of OOP

As we already mention, there are no perfect programming languages or methods. OOP also comes with a few downsides, so let’s check them out here.

1. Programming complexity

A lot of programmers avoid OOP simply because it’s so convoluted. Experienced developers take it for granted, but the fact remains that beginner-level programmers don’t think OOP is user-friendly and easy to handle. 

2. Large programs

A typical OOP-based system contains a lot more lines of code than software built with other programming methodologies. Procedural programs are simpler and more attractive for most developers. 

3. Slow-running programs

Compared to procedural programs, OOP systems are much slower. That’s because more often than not OOP systems demand a whole range of instructions to be launched and executed. 

4. It’s not an all-around solution

OOP is not suitable for some sorts of programs. This downside of OOP actually applies to all programming styles because there is no solution that suits all types of problems. 

The Bottom Line

Object-oriented programming is one of the most useful concepts in modern programming, but it’s far from being perfect. The methodology is similar to all other programming languages, which means that it comes with both positive and negative aspects and features.
