In today’s day and age, we are surrounded by devices everywhere we go. In our pocket, at all times we carry a tiny computer that is powerful than rockets made in the ’60s. Then we go to our houses filled with even bigger computers by a car which also has a computer inside it. We wear a tiny computer on our hand, which tells us the time and collects data related to our health. In short, a huge portion of our lives is dependant on machines and that portion in the future is only going to increase. The sociological effect of such a predicament is not what we’re going to be talking about. We’ll be talking about how it is highly imperative to understand what’s going on inside the machine and how it works otherwise, we’ll be rendered helpless when they don’t work. Hence, learning how to code is a skill that everyone should learn, at least the basic bit of it.
If you are not coming from a computer science background or a BSC.IT background and have never coded a single day in your life, then don’t worry it is quite alright for it is never too late to begin. When you newly pick up learning how to code it can get very intimidating due to the amount of knowledge that exists. When you begin you will get overwhelmed with all the new terminologies and concepts that will come your way. Remember, starting, is the hardest part of any new task you take up.
So, where do you start?
When beginning to learn how to code the first question you would be asking yourself is with which language do you begin programming. There are many computer languages out there with many certifications programs. Like java certification and python certification are two different courses. Every language has to be learnt separately so which should be the first language that you choose to code in?
The most popular answer to that question in the programming community is Java or maybe C++. Python is also proving itself to be a strong contender but Java wins by a landslide. Many engineering colleges have Java in the first semester of engineering which goes to show that even the Indian education system feels that Java is a wonderful language, to begin with. It is also highly used in important software and is highly powerful in terms of safely and portability.
Java is a really simple language with a lot of implementations in the industry. The largest companies in the world including Google, Netflix, Uber use Java in its Tech stack, one way or another. Due to its heavy industry application potential, java is the first choice for many users. Java is object-oriented which means that one will need to learn the basics of object-oriented programming (OOPS) to develop software. OOPS is a form of coding which is the foundation of every high-level language. In this, we create an object to interact with the functions and variables of other classes, because of which code sharing and code reusability are improved. Java is also a very secure language. Java runs separately on a virtual machine. JavaVM is independent of the operating system of a computer. So once the code has compiled, it would be possible to run the java code on any device with the JavaVM. Since it doesn’t need to interact with the OS, the host machine is very secure from viruses and malware. All this makes getting a java certification a great choice for beginners.
Python is a fairly new language and one of the most versatile languages. The creators of python wanted to make a language such that coding in it would be as good as speaking in English and they’ve come pretty close to achieving that. It also has a smooth learning curve as well as a huge demand in the market. Python is an open-source language which means that anyone and everyone can go about adding new functionality to it, making it a language filled with features. Since it is open-source, it also has a huge community of developers who are always ready to help new learners in their journey. Python is an interpreter, unlike Java which is a compiler. In recent years, ever since the advent of AI and Machine Learning, python has gained a great impetus. Building algorithms in Computer Vision, Natural Language Processing, Recommendation systems using Deep learning can all be done using Python and is a great choice if you want to get into that field.
In today’s world data is generated like water flowing down a steep hill, with great speed. All of this data is consolidated and stored in databases. A collection of huge databases is called a data warehouse. We create applications that interact with databases by the manner of giving and receiving data. MySQL is a language that we use to interact with databases and select data points. MySQL is a querying language and does not involve object-oriented programming. We use it to create a database as well as to add tables and values inside the table. We integrate MySQL with other languages like Java and Python to create complete applications with a user interface. It is also used in PHP for web applications.
Finally, the last thing we will tell you is having a certificate will make you seem more legit and attractive to potential employees. So make sure to enroll for a java certification program if you’re interested in java or whichever one you may see to be fit. Not having a certificate will render you useless during your job search, so all the best with learning how to code!
