Object-Oriented Programming has become a fundamental part of software development. Because of programming languages like C++ and Java, one can develop software for any platform including for mobile. Even in serious web development, the use of Object Oriented Programming languages like PHP, Python and Ruby is used.
Wrapping the head around Object Oriented Programming concepts can be quite challenging for IT professionals in the beginning. One may wonder what the use of Object Oriented Programming is when one can simply make use of the top-down approach of any traditional structured programming languages like Visual Basic.
If you have written this sort of software, you would usually break the large problem into subproblems in the logic and solve them individually in separate units of codes. A programmer can make use of functional programming that will look at elements of code as precise mathematical functions that prevent one from affecting other elements thereby preventing all kinds of side effects.
The Object Oriented Programming, on the other hand, is a whole new way of solving a problem. It starts with creating classes instead of writing a program which becomes a template for containing functions and variables. Objects become self-contained instances of these classes and it can be got to interact in exciting ways making possibilities of program features endless.
Here is a list of the advantages of learning Object Oriented Programming concepts:
- Easier troubleshooting possible thanks to Modularity: The problem with other programming languages that use Widget file is that the programmer has no idea where to look when something goes wrong. Programs in these languages require elaborate commenting so you can find things. But with encapsulation, objects are self-contained and every bit of functionality carries out its own functionality while not disturbing other bits of codes or their functioning. Modality allows the teams to work on several objects at the same time while minimizing the chance of a person duplicating another’s functionality.
- Inheritance allows for reuse of code: Let’s understand this with an example. In case in addition to the House object, one colleague would need to add KitchenFurniture object, and another needs to add a DiningFurniture object. All the developers involved build their objects separately but can discover commonalities between them. It is just that each object is just a different kind of furniture. This is where the inheritance technique can save time. Create one generic class (Furniture), and then the subclasses can be defined (DiningFurniture and KitchenFurniture) that will just inherit the traits of the generic class. Of course, DiningFurniture and KitchenFurniture will still have their unique functions and attributes.
If the DiningFurniture object needs a method to “Pick size of dining table” and the KitchenFurniture object requires a Chimney, each class can implement separate functions just for itself. Since both classes inherit main aspects from Furniture class, for example, the “wood type” or “color” methods, your inheriting classes can simply reuse existing code instead of writing these functions all over again. If you want to make the same change to all the Furniture objects, you simply make the change in the Furniture Object, and all furniture objects will inherit the new code!
- Problem-solving is effective: With top-down languages like C, the possibility of the program collapsing because of its complexity is greater. In a function-style program like Haskell can get taxingly long. Object Oriented Program, on the other hand, allows one to break down the software into smaller sized programs that one can solve one object at a time. When you would like to solve complex programming challenged and would like to add code tools, then OOP is the best!
- Flexibility done with polymorphism: With this example, one would need a few functions (or builds) like “buildDiningFurniture”, “build furniture” and “buildKitchenFurniture”. BuildKitchenFurniture share traits with BuildDiningFurniture, but other things like KitchenFittings and DiningChairs are unique.
Here is where OOP’s polymorphism comes to the rescue. Since a single function can shape-shift to adapt to whatever class it is in, one can create one function in the parent Furniture class called “build” – this one function would work with BuildDiningFurniture and BuildDiningFurniture.
These extremely useful features of Object Oriented Programming concepts OOP languages much in demand in the IT industry, naturally making skilled employees in the concept also in demand! Learning OOP in the foundational stages helps form a great foundation for learning higher concepts and tougher languages.
