Java VS. Python, Who Does What?


Javascript and Python are two of the most famous and important programming languages that are out there today. They both have their own advantages and disadvantages and so their own fans and haters! It is actually quite unfortunate to see that such heavy biasness has formed among programmers regarding all different languages and obviously everyone believes theirs is the best. This is however not always true as the spectrum of applications for each of the programming languages is so wide that it is technically impossible to call one superior to the other or,  cover everything in just one peice of an article -and don’t even get me started on the overlaps!

Selecting the correct language for the job is a pretty easy task when an individual is well-versed in both of them however, for a newbie who is just getting started with coding or is not familiar with the syntax and flow of either one, choosing the correct language for starting their education is not so simple. Without having enough experience and knowledge about the matter, one will easily fall into the trap of the wrong language and they often learn about this when they have already dedicated a huge amount of energy and resources for mastering it. 

Of course similar to human languages, there’s absolutely no harm in knowing more than one programming language either but the frustration and mental exhaustion that will hunt you after you realize you have taken the wrong path for your project is not going to be fun! That is why it is generally important to know what the differences come down to between all the programming languages. In our article “Coding, What It Is & What It Isn’t” we have fully discussed what programming languages basically are so if you are not sure about your foundations on the matter, I highly recommend reading that first before continuing with this one.

Now let’s move forward!

A Brief Look At Java & Python

Let’s be real here; a brief look will probably do no good for neither Java nor Python and that’s why we have separate posts on both of them “Java; The Best For Coding Anything” and “Python, The Programming Language That Doesn’t Bite!” so feel free to follow those too if your curiosity is being tickled. However in this part we are only going to tip our toes in either pools of the languages just enough to get us going with the rest of this post.

What Is Javascript?

Javascript, also known as Java, is among the most high-level and robust programming languages. It was first developed by Sun Microsystems which was a mega technology company based in the US. They are those who either directly created or played a key role in the creation of some of the most game changing software and information technology products such as NFS (Network File System) and Java. 

Java is designed to mostly lean towards object-oriented projects such as those that are involved with encapsulation and abstraction concepts. As Sun Microsystems was a computer and computer component manufacturer too, they mainly designed Java to be used in smaller handheld devices, set-up boxes and similar devices. What they hadn’t planned tho was the fact that it could be used by internet users for creating a variety of things in the world wide web ecosystem. However as soon as they realized this, which was during the time the internet was massively gaining popularity, they immediately modified it for the internet users.

What Is Python?

Similar to Java, Python is also an object-oriented programming language and is a high-level language. It is true that Python has only been gaining its popularity over the past decade or so, what you probably didn’t know is the fact that it was actually first developed in the late 1980s.

The syntax of Python, which is the equivalent of vocabulary and grammar in human language, is much simpler and way more readable than many other programming languages as the initial developers squeezed in many English words within the language structure. Some of the main applications of this language are in AI (Artificial Intelligence), machine learning and web design.

Comparison of Java With Python

Java VS. Python, Who Does What?

Now that we have established some basic information about both languages, it is time to dive into what separates them from one another. After all, if they were the same inside out, why bother developing two sets of languages? And more importantly why bother learning both of them?

The truth here is that the fact that they are both object-oriented or are considered high-level languages, by no means, makes them related nor identical. It is true that there are quite a few areas where the two languages will have overlaps in terms of their general flow and applications and they can sometimes be used interchangeably, they still serve distinguished purposes. 

One thing that is important to point out here is that when we talk about using the languages “interchangeably” does not mean that they could be used simultaneously in the same compiler or lines of code. Basically you can not use multiple programming languages all at the same time. It’d be like saying a sentence using English, French, Mandarin Chinese and Russian all at the same time!

Let’s take a look at an example. Website design is one area that has been gaining popularity as both a side hustle as well as a main career. Designing a website is something that can be done not just using Java or Python, but also through a large number of other programming languages such as PHP. There are also countless services and plugins such as Wix and Elementor which entirely eliminate the need for any coding when it comes to websites. This is one of the most common areas where Java and Python overlap in terms of application.

Now let’s get to our comparison.

Speed And Convenience

This is one of the most critical areas when it comes to coding. Imagine a computer software that you use everyday, say Microsoft Office Word! Or a game you or your child play most often. Do you know how many lines of code must be written by the programmers for a typical software or game to work? Hundreds of thousands! When writing code for a line follower robot the element of how quickly the code can be written and executed is not a big deal. This is because you will be working with something like 100 lines of code. This however becomes really problematic when it comes to more complex projects.

Java is written statically while Python must be laid out dynamically. What this means is that Java can be written directly in a compiler -which is basically the software used to turn code into computer language. This means that code is being checked in terms of syntax and executability simultaneously. Things aren’t the same way in Python though. The code for Python must be written in a text format inside a third party writing software such as your typical Notes software of the windows. Once the coding is done, the programmer must then copy and paste their code into the compiler as a whole, set the compiler to check the syntax and execute it.

Being able to statically code Java brings multiple benefits. The first advantage that this will provide a programmer with is the fact that the code is being checked while being written. This is very similar to writing an essay in Google Docs where there is autocorrect along with spelling and grammar check tools compared to writing in the Notes app which doesn’t detect any of the mistakes you might have made. This means that the Java programmer can edit and modify their code on the fly while the Python writer has to first finish everything and only then find out if they have made mistakes. 

Another benefit which helps the Java programmer have an upper hand in terms of speed is the fact that their syntax is being checked as they type it in while the Python expert must take one extra step and submit their work for checking in a separate step. This means that the Java code can be immediately executed while a  Python programmer must literally take one step more compared to the Java guy!


Java VS. Python, Who Does What?

This one is one of the areas where  Python beats Java without breaking a sweat! Generally speaking, Python requires much fewer lines of code for executing a task compared to what Java requires. This is mainly due to the fact that was mentioned earlier about the implementation of more English words into the command system and syntax of Python.

The task that is often used for measuring this criteria is what is known as “THe Hello World Program”. This is simply telling your computer to display the phrase “Hello World” on the screen which is basically like the first ever topic when ones starts to learn programming. Now let’s take a look at the syntax in each of the two languages.


public class Helloworld{

public static void main (String [] argos){

System.out.printIn(“Hello World”);




print “Hello World\n”

As we can clearly see, it only takes the Python developer 1 very simple line of code for displaying the phrase “Hello World” for their user on the screen while the Java programmer must write 6 lines of code -it’s 6 line because the blank line as well as the two ending brackets also count as line in programming and No, you can’t write them all in the same line.

Now let’s take a look at another example!

The Addition Example


public class Addition{

public static void main(String [] args){

int a = 15;

int b = 5;

int sum = a + b;





a = 15

b = 5

print(a + b)

Again as we can see, Python does the job in much fewer lines of code than Java does. This means that coding in Python is generally much easier and less troublesome because technically fewer lines of code mean fewer mistakes right?

This occurs because Python happens to operate in a more intelligent manner compared to Java. In the example above, Python is actually able to automatically detect the type of variable by looking at its value while in Java, the programmer must enter every single detail. For instance, the “int” phrase that was written before “a” is short for “Integer” which is declaring to the computer “Hey this 15 you are recieveing is basically an integer”. If this line of code is skipped or written incorrectly, the compiler will fail to recognise 15 as a number and hence will be unable to perform an addition!

Areas of Application

Java VS. Python, Who Does What?

Now let’s take a more in depth look at the applications of each language. As previously mentioned, this is also another key factor. Knowing what your language can or can not do is one crucial thing but not enough, you must also know the areas of weakness as well as the strength of the language you are going to base your project on. It is true that both Java and Python are versatility monsters but still, they have a couple of Achilles’ heels here and there.

Let’s take a look at the most common use cases of Java.

The first and most common use of Java is in developing mobile and web applications. This is due to the powerful object-oriented tools and perspective of the language. It is also most commonly used for developing enterprise softwares and applications. These are computer programs that are designed specifically for one business or a company and are completely customized according to their requirements and needs. Android applications are also mainly developed using Java. It is true that Python can be used for android app development as well, but since Google has based the core of Android on Java, it is always going to have that certain edge in comparison to technically any programming language.

Python, on the other hand, is more popular for its applications in the field of artificial intelligence, machine learning as well as web design. The difference between Java and Python when it comes to web design is that Python is generally used for back-end while Java is mainly used for front-end development. For example the back-end of Youtube is based on Python. This is manly because the graphical tools of Python are very limited.

Which One Should You Opt For?

What we spoke of in the previous paragraphs were to give you some basic idea about what each of the languages is capable of. In this section we are going to talk about what you should be doing in order to make the right choice in the direction you are going to take.

In short, you must adjust your sails in the direction of Java if you are planning to carry out tasks that are in the territory of software engineering such as creating custom made softwares for large or medium size enterprises, or work in companies which generally work in this industry such as Microsoft and Adobe. Also, if you are heading towards the front end development of websites or developing Android applications, Java should be your main concern.

On the other hand, if you are leaning more towards artificial intelligence, machine learning, robotics and fields of such, Python should be your clear choice. Also back end web development will require mastery in this programming language as well!

What’s In All This For Your Child

Java VS. Python, Who Does What?

As we have established throughout this article, both Javascript and Python are extremely useful to learn. If your child is already in contact with one of these languages, then the decision of which direction they are going to make is a much easier one. 

However if they have no prior experience with programming, enrolling your child for a few sessions of each language will guide both you and them toward making much better and well-informed decisions along the way!
