Advantages Of Object Oriented Programming
Object-oriented programming is such a fundamental part of software development that it’s hard to remember a time when people used any other approach. However, when objected-oriented programming, or OOP, first appeared in the 1980s, it was a radical leap forward from the traditional top-down method.
These days, most major software development is performed using OOP. Thanks to the widespread use of languages like Java and C++, you can’t develop software for mobile unless you understand the object-oriented approach. The same goes for web development, given the popularity of OOP languages like Python, PHP and Ruby. That said, many developers start off with top-down languages like Visual Basic or JavaScript.
You may be used to breaking down large problems into sub-problems and solving them in separate units of code. Or you may have experience with functional programming, which treats elements of code as precise mathematical functions, and prevents them from affecting other elements — that is, no side effects. Come to grips with OOP, however, and you’ll see that it offers a whole new way of solving problems.
With OOP, instead of writing a program, you create classes. A class contains both data and functions. When you want to create something in memory, you create an object, which is an instance of that class. So, for example, you can declare a Customer class, which holds data and functions related to customers. If you then want your program to create a customer in memory, you create a new object of the Customer class.
1. Re-usability
It means reusing some facilities rather than building them again and again. This is done with the use of a class. We can use it ‘n’ number of times as per our need.
2. Data Redundancy
This is a condition created at the place of data storage (you can say Databases)where the same piece of data is held in two separate places. So the data redundancy is one of the greatest advantages of OOP. If a user wants a similar functionality in multiple classes, he/she can go ahead by writing common class definitions for similar functionalities and inherit them.
3. Code Maintenance
This feature is more of a necessity for any programming languages; it helps users from doing re-work in many ways. It is always easy and time-saving to maintain and modify the existing codes by incorporating new changes into them.
4. Security
With the use of data hiding and abstraction mechanism, we are filtering out limited data to exposure, which means we are maintaining security and providing necessary data to view.
5. Design Benefits
If you are practicing on OOPs, the design benefit a user will get is in terms of designing and fixing things easily and eliminating the risks (if any). Here the Object-Oriented Programs forces the designers to have a long and extensive design phase, which results in better designs and fewer flaws. After a time when the program has reached some critical limits, it is easier to program all the non-OOP’s one separately.
6. Better productivity
with the above-mentioned facts of using the application definitely enhances its users overall productivity. This leads to more work done, finishing a better program, having more inbuilt features, and easier reading, writing and maintaining. An OOP programmer cans stitch new software objects to make completely new programs. A good number of libraries with useful functions in abundance make it possible.
7. Easy troubleshooting
lets witness some common issues or problems any developers face in their work.
- Is this the problem in the widget file?
- Is the problem is in the WhaleFlumper?
- Will I have to trudge through that ‘sewage.c’ file?
- Commenting on all these issues related to code.
So, many times, something has gone wrong, which later becomes so brainstorming for the developers to look where the error is. Relax! Working with OOP language, you will know where to look for. This is the advantage of using encapsulation in OOP; all the objects are self-constrained. With this modality behavior, the IT teams get a lot of work benefits as they are now capable of working on multiple projects simultaneously with an advantage that there is no possibility of code duplicity.
8. Polymorphism Flexibility
Let’s see a scenario to better explain this behavior.
You behave in a different way if the place or surrounding gets change. A person will behave like a customer if he is in a market, the same person will behave like a student if he is in a school and as a son/daughter if put in a house. Here we can see that the same person showing different behavior every time the surroundings are changed. This means polymorphism is flexible and helps developers in a number of ways.
- It’s simplicity
- Extensibility
9. Problems solving
Decomposing a complex problem into smaller chunks or discrete components is a good practice. OOP is specialized in this behavior, as it breaks down your software code into bite-sized – one object at a time. The broken components can be reused in solutions to different other problems (both less and more complex), or either they can be replaced by the future modules that relate to the same interface with implementations details.
A general relatable real-time scenario – at a high level, a car can be decomposed into wheels, engine, and chassis soon. Each of those components can be further broken down into even smaller atomic components like screws and bolts. The engine’s design doesn’t need to know anything about the tires’ size to deliver a certain amount of power (as output) has little to do with each other.
