What is OOP?
Technical descriptions are often very confusing as the reader is not able to relate to its experiences. This blog primarily focuses on the fresher’s as they have a very limited understanding of the real world and finds difficulties to know what this definition exactly means. One such topic is “OOP” which has several definitions available – we have chosen a basic approach to help our readers to better understand OOP meaning and advantages of OOP.
As per Wikipedia
Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods.
This is a great definition for those who have some working or practical exposure of the language, for people who are fresher the above definition will leave speechless.
OOP (object oriented programming) is a programming paradigm that is completely based on ‘objects’.
A general explanation of ‘object’ for better understanding – Mr. A is going to build a POT with the use of BLOCKS. Blocks are a kind of measurement units like height, radius, and shape by default. These properties are there by default, means if you use a block it has some dimensions associated with it. Now there are some other crucial properties that are not yet assigned like – color, material, and price.
So, Objects are nothing but POTS. We build an object by assigning values to the properties when we need them. BLOCK is nothing but the templates of the object. There we write how the object should appeal (means look like) and how the actions will take place. In Java, we call it a class.
Advantages of OOP
Moving to the advantages of OOP, we would like to say that there are many as this is one of the core development approaches which is widely accepted. Let’s see what are the advantages of OOP offers to its users.
It means reusing some facilities rather building it 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 the 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 with incorporating new changes into it.
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 longer 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, finish a better program, having more inbuilt features and easier to read, write and maintain. 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 a time it happens that 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 to work 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 flexibility and helps developers in a number of ways.
- It’s simplicity
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. In doing this 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 which 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, a chassis soon and 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 size of the tires in order to deliver a certain amount of power (as output) has little to do with each other.
