Java Or Python :Which Programming Language Is Best For 2021

By – HtmlCssMonk

Both Python and Java are widely used general purpose programming language. The November edition of TIOBE’s top programming languages list holds a surprise: For the first time in its 20-year history, C and Java don’t occupy the top two spots, with Java slipping to third and Python taking its place. . At present, developers use Java and Python for developing a wide variety of desktop applications and web applications. Both programming languages are also used widely for machine learning and data science.

 Today, everything we dwell upon has to have a programming language behind it, easing away our troubles. So, let’s compare Java and Python , and try to figure out Which programming language is Best for 2021 !

Introduction

Java

Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

Core Java has strong support for web development. While Java on the desktop, with the notable exception of Eclipse RCP based application, was never a huge success, Java is frequently used at the server side.

The write once, run anywhere programming language has come a long way since its inception under the development by Sun Microsystems. It is quite similar to C, but on the other hand, easier than it. Java also goes well when combined with Node JS, Android, spring in line to develop a large-scale application that is bound to perform.


Python

Guido van Rossum created this programming language in the early 1990s. Django is a free and open source web application framework, written in Python. Its initial release was in 2005. Multiple languages inspire python, including C/C++, Java, Perl, Lisp, and ICON.

Python is one of those rare languages, which can claim to be both simple and powerful. Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming.

The codes in Python are easily readable and is also much easier to learn and adapt. Python is also in great demand for data science, web development, and other educational applications. Even the likes of Instagram and Google uses Python for their object-oriented viral programming applications.

Key Features

Java

a) Simplicity

Java has an easy user experience for developers and users. The inbuilt libraries have the most significant advantage when compared to similar object-oriented languages.

b) Portability

 Anytime anywhere language has a wide range of software and hardware.

c) Security

 There are strong security standards blends with safe programming.

d) Allocation

 Stack provision, garbage collection, and automatic memory distribution make Java different from other programming languages.

e) Distributive

 Java is a network competent language. It receives and sends files informally. 


Python

a) Python supports multiple programming

Python is a multi-paradigm programming language having features like object orientation, function, procedural, imperative and more.

b) Cross-platform language

The language supports different operating systems like Ubuntu, Linux, Windows, etc. . This means if the Python developer codes on Mac, it will smoothly run on Windows.

c) A large set of library tools

Having extensive libraries and tools that improve the overall functionality, the language is easy to code. Here are a few libraries:

  • Built-in functions, exceptions, constant types.
  • File format, file, and directory access, multimedia services
  • Graphic User Interface Development Tools
  • Custom Python Interpretation
  • Scrappy, wxPython

d) Huge Community Support

Whenever there is an issue, the Python community resolves the issue. You will also get innumerable ideas regarding the technology and the change in versions.

Syntax

Another significant difference between Python and Java is syntax simplicity. Python is easier to use.

Let’s take a look at the classic “Hello World” program.

In Python, someone would simply enter:

print (“Hello, world!”)

On the other hand, the Java version would be more complex. It would be more like:

public class HelloWorld { 

            public static void main (String[] args) { 

                        System.out.println(“Hello, world!”); 

            } 

Java is also more vulnerable to small coding errors that are easy to make and harder to locate.

For instance, in Python, the semicolon is optional. In Java, the semicolon is required. A missed semicolon causes an error.

In contrast, Python uses indentation to define blocks which improves code readability. Java uses the curly brace, {}. A missed/misplaced curly brace will cause a syntax or semantic error. 

Performance

Java

Java’s efficiency largely comes from its Just-In-Time (JIT) compiler and support for concurrency. The JIT compiler is a part of the Java Runtime Environment. It improves performance of Java programs by compiling bytecodes into native machine code “just in time” to run. Java Virtual Machine (JVM) calls the compiled code directly. Since the code is not interpreted, compiling does not require processor time and memory usage. Theoretically, this can make a Java program as fast as a native application.


Python

While Java programs are compiled directly, Python is interpreted which slows down Python programs during runtime. Determining the variable type which occurs during runtime increases the workload of the interpreter. Also, remembering the object type of objects retrieved from container objects contributes to memory usage.

Popularity

Popularity has always been a game between these two languages, as they’ve been a close competitor in the top 3 positions of popularity, along with JavaScript. Before the JavaScript revolution, Java was the number one most popular language.

Developers of JavaScript were smart enough with the naming of their newly developed JavaScript, though. As the programming language shares a similar name to that of JAVA, it attracted a lot of popularity during its initial days. 

Popular projects

Java

Java is widely spread and one of most powerful programming languages, which gives power to a lot of projects and famous websites. Here are some examples of famous projects done in Java.

Facebook

The most popular social media is also powered by Java. Facebook uses HBase (a Java-based No-SQL DB) as messaging platform and also uses Java in other areas.

Amazon

Love online shopping!! Amazon also uses java in addition to other languages.

eBay

eBay Inc. is a multinational e-commerce corporation based in San Jose, California that facilitates consumer-to-consumer and business-to-consumer sales through its website. eBay architecture is based on java.

Google

Google uses Java extensively in Google Plus, GTalk (High Scalability – High Scalability – GoogleTalk Architecture) etc

Linkedin

LinkedIn is a business and employment-oriented service that operates via websites and mobile apps. Primarily it is written in Java.


Python

Python is an incredibly powerful and useful computer programming language that many of the biggest websites in the world rely on for their foundation. Here are some famous software programs that are written in Python.

YouTube

YouTube is one of the most popular sites on the Internet, and it runs on one of the most powerful languages in Python. The foundation for Python helped YouTube integrate streaming videos into their pages, as well as the ability to like videos and embed certain information.

DropBox

With Python at the root of DropBox, there is no longer a need for USB sticks or blank CDs, since you can now save and share everything with your cloud-based account. This program lets you save files to a cloud-based service, that you can then access from anywhere in the world.

Google

It takes a lot of power to be able to handle the most popular search engine in the entire world. That is why Google uses Python for its mainframe foundation. The ease that Google provides for finding certain information would be impossible without Python at the core.

Quora

This site compiles a list of questions and answers that come from a community of individuals. The creators of Quora, who were former Facebook employees, decided to use Python to help them create.

Spotify

Spotify changed the music game when it allowed you to listen to ad-free music of your choice. However, whether you are rocking out to the latest K-Pop song from Psy or a classic jazz tune, you are doing so because Spotify was built on Python.

Final Words

So as you came across this article, you would have understood that both Python and Java are popular, and at the same time, quite powerful programming languages to consider in 2021. Also, perpetual resources available for training purposes concerning both the languages will make the learning process for beginners a seamless one. Based on your business purpose and product requirement, you can choose an ideal programming language for you.
