Reasons why learning Java is still worth it – Rinu Gour

Java isn’t platform-independent; it is a platform.”


There’s no denying the fact that the last few years have been the years of Python. The dominance Python has had in these years doesn’t require any recognition. Programming aspirants these days are crazy for learning Python.

Though Java once had the same craze among the programmers and believe me, it still has got some dominance to prove to the IT world.
This might be the era of Python, but Java hasn’t lost its worth at all.

Often we find ourselves in a dilemma of which programming language is going to prove itself long-lasting and is going to shape our career in many ways.

Why is Java so Popular?

As a programmer, one probably looks for rapid progress, and to choose the best programming language is your basis to start with. Even if you try to find the best programming language, to begin with, you will find many different options.

There are at least six most popular programming languages, whose rankings keep on changing with time. Therefore, we can’t say any language as the best language as they all serve different purposes.

And here you’re facing a situation of indecision between Java and Python. This is probably the most common confusion that a programming aspirant comes across these days.

And I’ve got your back in this. I’ll make you aware of why being old school is still cool.

According to the TIOBE index for February 2020, Java firmly stands in the first position with the most significant number of searches through the most popular search engines.

While the Python language stands at the third position.

Why Choose JAVA Over PYTHON?

Java and Python are very similar and are two of the most trending buzz in the IT industry.

Java is faster than Python

Python is comparatively slower since it is interpreted language. Because it has a very easy logic, but half of your time will be spent on optimizing the runtime errors.

Multithreading is possible in Java

Java also enables real multithreading while Python’s threading is sort of virtual. It’s JVM is pretty solid. Python is inhibited by the GIL (global interpreter lock), which does not make it goof for multithreading.

Know the Class of Java

Java is truly WORA(Write Once, Run Anywhere)

The compiled code in Java can be run on any machine without recompiling it which makes it more portable than Python.

Java is safer and powerful than Python

Java is a safer language to use because it is a statically-typed language. Python is a dynamically typed language that makes it unsafe. Java is far more explicit and more strict than Python which makes it more powerful than Python.

Java has a rich set of APIs

Java has a far richer and far more robust ecosystem of libraries and tools. Its rich set of API helps to expand knowledge about Java language. A major portion of Python is written by script kiddies.

Java is very nit-picky

This is not only a good quality for beginners but also equally good for even experience holders and seniors in Java. Programmers usually tend do make stupid mistakes and Java is very good at pointing them out. Languages like Python will just pass such mistakes as warnings without giving a compilation error.

Java is an “Evergreen Programming Language”

Java is an evergreen programming language that is being used in most organizations. Python is not used as a primary language for most applications.

Python is too easy

There is a saying that you should be making things as simple as possible. Python suffers greatly from making things too simple. In Python, you assign a value to a variable without specifying its type. In Java, in order to initialize a variable, you must specify its type.

Get Cozy with Python

For exampleIn Java, for declaring a variable you would write

dataType name = value;

In Python, you just need to write

name = value

It looks much better, as you don’t need to specify a type, but in practice causes many problems. Anyone can easily overwrite an existing variable or can accidentally create a new one. So in Java, if you make a type and write dog = 5; it will give an error (unknown variable), while Python will just create a new variable called dog.

Python is easier to write while Java is easier to read!!

Here is how printing “Hello World” in Java looks like:

class MyClass{
public static void main(String[ ] args) { System.out.println(“Hello World!”); }}

Here’s the same in Python:

def main():     print(“Hello world!”)main()

Still not impressed?

You can not refrain from these interesting facts about Java:

  • Approx 95% of enterprises use Java as their primary language. This ratio is much more than C and other languages.
  • Java gets downloaded one billion times in a year.
  • A median salary of a Java developer is $83, 975.
  • Today, Java rationally runs on more than 1 billion Android applications as the Android operating system of Google uses Java APIs.

Securing Your Career with Java

When you get familiar with the JVM(Java Virtual Machine), you can easily use other languages that are similar to its environment. For example, Scala, Groovy, Kotlin, and Clojure.
Anyways, Java itself will always encourage your progress.

Java isn’t the world’s most popularly used programming language for no reason!!


Java can do more

“Java is an ocean of opportunities.

if(your goal is getting into AI or ML or Data Science)
then choose Pythonelse(for everything else)
then choose JAVA

Oracle, as a measure of popularity, quoted the statistics telling — “There are nine million Java developers in the world.”
This statement perfectly portrays the demand for Java and its evolution in software development in the future.

Wrapping it Up!!

Why learn Java in 2020? Because you can utilize all the benefits of a security-oriented, flexible, and dynamic programming language. Java is among all-time leaders in the programming world. Java exists everywhere and is expected to become even more important in the Internet of Things (IoT) and Big Data developments in the closest time.

Building applications and platforms for any devices, such as computers, laptops, gaming consoles, navigation systems, terminals, monitoring facilities, etc., makes Java as the best programming language to learn in the world of Python.
