What Is Object-Oriented Programming?
Before OOP (object-oriented programming) we used Procedural Programming. In procedural programming, we write procedures or functions to perform certain operations on data. While in an object-oriented programming paradigm, objects are created containing both data and functions. The data is normally referred to as fields or attributes and functions or procedures as methods.
For example, we create a class of a “vehicle”. Each vehicle contains data or attributes like “name”, “make”, “model”, “number of wheels”, “speed” etc. Once you define a class for a vehicle, you know that a car, truck, bike or cycle all fall under this category of a vehicle.
So you don’t need to write or copy redundant lines of code to get or set the name of a vehicle. Following the procedural approach here, you would be writing the same lines over and over for all these vehicles. That would waste a great deal of time and energy. Effective implementation of OOP principles saves you from all this hassle.
There are 4 major pillars of OOP. Follow these principles if you want to effectively implement it:
What are the top languages to learn in 2021?
You will find a lot of mixed opinions on this, but let’s see why are we proposing this set of languages and how they can boost your career.
Java is a relatively older language, that makes it one of the most stable and thoroughly developed one. It follows the “develop once, run anywhere” rule, making it a sustainable object-oriented programming language that continues to develop to date.
It is commonly used for building relatively larger enterprises because it scales well. Giants like Google, Netflix and Amazon are found using it.
Its open-source libraries and frameworks make it easy to develop advanced functionalities even for amateurs. Due to the presence of Java in the market for a long time, it provides thorough documentation and extensive community to reach out to.
With Java, you can comfortably build cross-platform apps, android apps, desktop apps, web apps and even enterprise-scale applications. Its object-oriented approach, automatic memory allocation, garbage collection and security manager helps to build secure software.
If you are a beginner, you’d love to learn python because it’s one of the simplest to understand. Due to its syntax highly human-readable, it takes relatively lesser time to learn than other languages. Some surveys publish it to be the most popular in 2020.
Its use cases span desktop apps, web apps, GUI based apps and the most goto language for Computer Vision, Artificial Intelligence, Data Science and Machine Learning based software.
Python comes with a lot of useful libraries and frameworks like Django, CherryPy, Flask, NumPy, SciPy and Pandas etc. This language too has an extensively developed community and library support. From a lot of dynamic startups to market giants like Amazon, Google, Netflix and Spotify are found to be python users.
So if you plan to learn python in 2021, there are great opportunities waiting for you in the industry.
Go is a relatively new language, introduced, developed and backed by Google. Due to its limited functionality, it is not as much widely used. But its popularity is leading its rapid growth. A lot of silicon valley based startups are found using it.
Go was majorly developed to eradicate gawky software development patterns, and build more scalable software systems.
One of the perks to learn Go is that by being a professional you can land a job at Google, Nokia, SoundCloud or BBC. Since all of them use officially use it. If you’re not willing to switch, Go will enable you to charge great as an hourly paid freelancer. Some of the market surveys mention it as the second best-paid language for freelancers. So, if you’re a newbie learning Go can be an exciting experience for you in 2021.
If you are absolutely new to programming, we’d recommend learning C++ as it was designed especially to implement object-oriented programming.
Some people might complain about its syntax harder to grasp, but the fact is that pointers, self memory allocation and manipulation give you an incredible amount of control while programming.
Almost all the system-level programming like file systems and operating systems is carried out in C++. Not only that, you can develop a real-time GUI based desktop app, gaming app, mathematical simulations, low-level chips programming and even cloud-computing based apps with C++.
C++ being a solid, mature language provides you with STL (Standard Template Library) having multiple libraries to implement the features you desire. Along with that, the C++ community is always there to rescue. For your ease, some considerable names using C++ are Walmart, Mozilla Firefox, Google and the currently booming messaging app Telegram.
So if you’re into building apps of that scale, you should definitely give a thought to C++.
You can not just magically become a professional if you start learning a language on your own. After you have learnt the fundamental principles of programming and some syntax, we encourage you to apply to various reputable companies that align with your goals. This way, you can achieve your personal milestones and become a professional simultaneously. Happy learning!
