Between Java and Python, which one is better to learn first and why?

Python.

Don’t even think about it to select another language as your first. Why? Well,

  • Python is easy. Trust me on this one. My first major language was C++ and it lead me to contemplating a career change. Here’s a short snipped of C++ code for displaying “Hello world” on the screen -
#include <iostream>
using namespace std;
int main()
{
	cout << "Hello world!" << endl;
	return 0;
}

Here’s the same thing in Python

print("Hello world!")
  • Python is dynamically typed. What in the world is that? Okay, so computers are dumb. They aren’t smart enough to know that 1
  • 1 is a number, or specifically, an integer and that “hello” is a word or “string” in computer talk. So because of that some programming languages needed to specify the kind of stuff they were working with. For example if you needed to add two numbers in Java, here’s what you’ll have to do -
class AddNums(){
	public static void main(String args[]){
		int first = 1;
		int second = 2;
		int sum = first + second;
		System.out.println(sum);
	}
}

You see that “int” keyword? That stands for “integer” and that basically just tells the computer, “Hey, I need something to store this number but since you’re too stupid to know that it’s a number I’ve specified it and so you should remember that the variable called “first” can only store integer values and I’ve given it the value of 1

1. And so on with “second” and “sum””. That’s what’s up with Java. In Python?

first = 1
second = 2
sum = first + second
print(sum)

Do you see how clean that is? Notice the serene absence of semi colons.

  • Python supports all styles of programming. Okay, this might be a little controversial but it still worth mentioning. Broadly, there are two methods (no pun intended) of programming - object oriented and procedural. I’m not going to get into details but, long story short, they’re both great ways of approaching problems but Object Oriented is better suited for large scale projects and will, if done right (a huge deal in itself), be cleaner. Procedural is better for small projects to get things, just, done. For example -
class Hello{
	public static void main(String args[]){
		System.out.println("Hello world!");
	}
}

vs

def main():
	print("Hello world!")
main()
  • Now both Python and Java support OOP (object oriented programming) but Java forces it upon you by giving you no other way out. That, for big companies and large scale projects, might be a good thing but for someone who doesn’t even know what a class is can be a big hassle. Python, on the other hand, lets you do your own thing. Again, this might be a bad thing but it’ll all depend on the kind of practices you pick up and follow. Ruby is another language and it is very similar to Python but I don’t like it as much because it’s way more lenient on coders. Python kind of maintains that fine line. But yes, for a beginner, Object Oriented might feel forced if all you need to do is write something to take in two numbers and print their sum but in the long, really long run, it could be a good thing.
  • Python is used almost everywhere. Web development? Check. Penetration testing? Check. Making awesome games? Check. Glue code for projects not native-ly written in Python? Check. Maching Learning? Double check that boy! Scientific research? Check. Academics? Check. Android apps and other scale-able projects…? Java is your thing. Native programming is one place where Python fails.


And I think that’s about it. Both languages are great in their own thing and what they’re used for but Python, hands down, is one of the best things a beginner could start with today.

Learning by Doing: How to Learn Java Basics by Building Your Own Project

Java is not the hardest language to start with. So, it becomes way popular among novice developers joining the ranks of Java coders every single day. If you are reading this blog post, you might be interested in learning Java.

Java is widely used across industry, and especially in the area of Enterprise software, which results in many high paying job opportunities and makes this programming language a common language for newbies. A general promotion of it within colleges and other institutions providing a formal Computer Science education also contributes to its popularity.

However, these are not the only advantages of Java — among other things, it allows you to adopt good practices and makes it way easier to learn other languages in the future. And with no doubt, you can easily learn it if you’re following the right approach. In this post, I am going to share some of them with you.

The Importance of Practice in Programming

Beyond all doubt, practice is important and valuable. But, before we get to the advantages of hands-on experience, I want to draw your attention to one essential thing I often tell my students.

New programmers who are just learning and start implementing things, without being supervised, often end up adapting bad practices. To avoid that, especially when you are making your first steps in programming, I recommend looking for a person who will supervise you and teach you. A strong mentorship with someone engaged in a serious project, as well as communication within the community in the form of sharing code and asking for feedback, is worth the effort. Similarly, when you are applying for your first job, you want to be looking for a company with a strong team and a good leader who would be keen on investing into your learning.

Now, let’s return to practical experience. Learning by doing is different from learning by passively consuming the information. To make sure we can use all the newly acquired technology, we should put our skills to test and write tons of code. The benefits of hands-on experience are almost endless.

Efficiency and Productivity

By practicing, you get a clear understanding of what programming is. Consequently, you start doing better with each new hands-on task, complete it faster, and thus become more productive.

Even if you are not working on real-world projects yet, it’s important to get used to having deadlines. They are inextricably linked to the programming process. My recommendation is to set up your own deadlines while practicing stage and follow them as closely as possible.

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.
