Python vs. Java: Which Language Is Right in 2023

If you are willing to build a career by learning programming languages and using them for software development, game development, web development, or websites to earn your living, then you have landed on the right page! 

Among All of the programming languages, the two most common options that all budding programmers prefer are Java and Python. People have been talking about Python for a long time now. Moreover, there are ample Python developers out there, setting an example of how good a career-centric programming language it is. 

But on the other hand, Java is also picking up a high pace in developing proactive and responsive applications. Thus, Java is now matching the demand alongside Python! Therefore, learning these two most popular programming languages will set you up for a good career ahead. 

But what should you learn first in 2023? Is Python going to help you crack the big-package jobs, or should you learn using JavaScript frameworks? As beginners, you need to learn the efficacies of both to decide on what would suit your needs and skillset the best! 

Understanding Java and Python

As per TIOBE, in August 2022, it was recorded that Python was unstoppable, with a market share of around 15.42%, whereas Java was ranked third after Python & C, with a market share of 12.4%. So, here’s what defines them both:


Java is defined as a general-purpose and class-based programming language, the syntax of which is quite similar to C & C++. It is mostly open-source and a platform-independent language, which allows the developers to be able to use the compiler on Java codes once and then use it over all platforms without the need for recompiling it. 

Moreover, Java implements dynamic abilities when the runtime is in pursuit, such as modifying & reflecting the line of code. These capabilities aren’t available in any traditional compiled language. JVM, or Java Virtual Machine, is known as the core of this programming language, as it loads, verifies, and executes the Java bytecode. 


Python is also considered a high-level & general-purpose programming language, which offers support for various programming disciplines, including the procedural, functional, or class-based disciplines. The advantage of Python over Java is that the coding is quite simple.

Whether you are developing an iOS or Android mobile app, the app development lifecycle becomes more organized, and the processes are executed at a faster pace. The professionals also say that the codes used in Python programming languages are easily readable, just like the English language. It is a low learning curve, which makes it more popular among the budding developers. 

Apart from the readability quotient and scripting of the Python language, it is also known for its efficient indentation, list comprehensions, and reference counting for digital and clear coding practices. Thus, it makes app development even easier with more flexible algorithms embedded in it. Python also supports sci-kit-learn machine learning algorithms for better development aspects. 

Java vs Python: Major Differences to Help You Decide!

Now, you have an understanding of how a Java developer differs from a Python developer in terms of its coding approaches and the definition of the programming languages. So, if you want to get rid of the dilemma of whether to go with Java or Python for your career in developing web applications or mobile applications, then here are some key differences for you to put an end to it:

1) Syntax

If you compare the Java code with the Python code, Python has a simple and understandable syntax, which is quite easy to apply and remember. Python allows better readability, which provides leniency to the coders with dynamic typing features. 

Java’s syntax is pretty much stricter, which means you cannot forget even the smallest of elements while you code. For instance, even if you are misplacing the curly braces in your code, then there will be compilation errors. 

2) Typing & Coding

Java supports nominative, safe, and static typing, and Python, on the other hand, has a strong, gradual, and dynamic typing discipline. Python leads the way in terms of coding proficiency, as it allows the developers to write only a few lines of code, and execute them, whereas, in Java, you need to write the entire stretch of code, to perform the same function. 

For instance, if you are building a data analysis application, then the number of lines of code to be written through Python will be less in comparison to that of Java. Hence, Python excels in the speed of the development ecosystem and reduces the turn-around time for the projects. Moreover, Python also supports object-oriented programming language, which the developers will mainly use for defining and calling a class with methods and attributes.

3) Library and Framework Availability

It is the area where Java has a large-scale advantage! Java has a lot of JavaScript frameworks for developers to work with to attain various functionalities. Some of the top ones are Hibernate, Play, Spring, and Grails. 

On the other hand, Python has only a few frameworks, but they are sufficient enough to help developers implement the best applications. Some of the top frameworks include Flask, Falcon, Django, and Dash. 

Just like that, some of the popular Python libraries include TensorFlow, Requests, Open CV, etc. On the other hand, some of the standard libraries include Google Guava, Apache Harmony, Apache Xalan, OjAlgo, and others. 

4) Database Connectivity

Java again beats Python in terms of database connectivity. It is because Java APIs are better in terms of functionalities. Among them, the JDBC (Java Database Connectivity) is primarily used for connecting with the database systems. The data structures are weaker in Python than that in the Java language. 

Hence, it might be one of the reasons why big-scale organizations often prefer Java over Python. Therefore, if you have plans to learn Python and want to work in a big technology company, then do your research accordingly.

5) Speed Differences

When you compare the speed, Java tends to be faster in comparison to Python. It is because Python is an interpreted language, and the data types of it are determined only at the time of compiling. Thus, Python slows down the process of executing the codes, whereas Java offers a faster compilation. 

6) Practical Implementation

In this aspect, the resourcefulness of the programming languages is determined, in which Python wins the battle. It is because Python has managed to keep up with upcoming technologies and trends, which contributes to its popularity. Hence. Python is now working alongside the DevOps movement for rapid application development practices. 

Java is also enjoying its refactoring support with the help of its static typing discipline. Moreover, it also boasts its self-memory management and extends support for various IDEs. Thus, even Java is a very reliable platform that even allows the development of cross-platform apps, which makes them work feasibly across all operating systems, may it be Android, iOS, and Linux. And it is possible because the interactive applications are compiled over the bytecode


Beyond Python and Java, there are various other programming languages such as PHP, Swift, Kotlin, Ruby, C++, SQL, and others. Even though all of the languages are highly proficient, the in-demand ones are Python and Java. 

So, if you want to build your career in leveraging technologies such as automation, artificial intelligence, big data, and others, you can take tutorials upon mastering these two popular languages and avail of the jobs with high earning scope.
