Python vs Java / Hebrew

Python vs Java / Hebrew

In the world Tiobe rating the Python programming language occupies the first line with a share of about 13.97% as of January 2024. The growth in 20 years is almost 12.7 times – agree, it is impressive. Java is also confidently included in the TOP-5. If we take into account the difficulty of learning C++, it is between Java and Python that novice programmers usually choose. We decided to compare these popular languages ​​and give some useful recommendations to choose between courses Java and Python was more aware.

What will have to do

We will not drag on for long and get to the point. What are the tasks that a pythonist will most likely work on at the beginning of his career path:

  1. Web development. Spotify, Netflix, Uber, Dropbox, Pinterest, Reddit and hundreds of millions of other sites run on Python. Even Google and Instagram*, which have two more than 91 billion visits per month, have Python in their stack. The plus of the language is that it is suitable for both small businesses that cannot maintain a staff of dozens of developers and large corporations.

  2. Data Science and Machine Learning. A topic that many have already had time to get bored. But Python is the key tool of a data scientist. With its help, developers write algorithms for ML programs and design powerful analytical programs.

  3. Automation. Everything related to scripting is also for Python. For example, additional modules for ready-made software and plug-ins for automatic software testing are developed in this language.

“Python” is less popular in game development, mobile application development, system administration, but it can still be used there.

If you can list the areas of application in Python, it is much more difficult with Java – this language is used almost everywhere. Banking and industrial software, applications for PCs and Android smartphones, web applications and servers, corporate software – these are just some of the spheres under Java’s control. The only thing is that the language systematically left gamedev, but otherwise the javaist has room to turn around.

What to choose? It all depends on the preferences: if you are interested in Data Science and web development – then Python is suitable, if you plan to take on more complex projects (such as developing a mobile application for a payment system or software for managing processes in a factory) – Java. In general, both languages ​​are quite universal.

Why choose Python

Reasons for the popularity of the language:

  • Simple syntax. Even very simple. There are no strict requirements for dots and commas, many commands are executed in one line. Python is easier to learn than other programming languages.

  • Easy reading. Python has a good and clear structure, it actively uses indentation, spaces and spaces for easy code reading. It is easier to understand the examples and look for errors here.

  • Dynamic typing. This means that variable types in a programming language can “move” across classes and functions. Dynamic typing provides the flexibility needed for large data processing tasks.

  • A rich ecosystem. There are a lot of libraries and tools here. Code templates speed up the programming process and allow developers not to get stuck on the same lines, but to focus on the creative component of the process.

Conclusion. Python is usually recommended for those with no prior programming experience. In order not to confuse the desire and quickly merge into the topic. At the same time, the language is flexible and widespread – Pythonists are in demand today, especially against the background of general interest in big data, machine learning and digitization.

Why choose Java

Reasons for the popularity of the language:

  • Cross-platform. It is often called the main advantage of Java. Usually, a developer writes software for a specific system – Windows, macOS, Android, Linux, etc. To switch from one to another, you have to rewrite and change a lot. There are no such problems with Java – the code will run everywhere.

  • Object-oriented language. Java demonstrates all the advantages of OVP – ease of modification, the possibility of rolling back to the previous version, scalability, etc.

  • High speed and security. Java is faster than Python and provides a high level of security—just what corporations, banks, and other large organizations need.

  • A large number of libraries, development environments, frameworks. Java has been around since 1995 – during this time, it seems, programmers have mastered the language.

  • Having learned to program in Java, you can easily learn Kotlin or Scala. A bonus for those who plan to deepen their knowledge of the field in the future.

  • Easier to learn than C-like languages. A significant reason if you have little programming experience.

  • Great community. Be sure that you will find an answer to any question from your colleagues.


Java is a strongly typed language among object-oriented programming. Choose it if you want to study the field in depth and, for example, create applications on Android. Be prepared for the fact that you will have to practice a lot. For clarity, we show code examples:

How to output the phrase “Hello everyone!” in Java:

public class HelloWorld {

        public static void 

main(String[] args) {


System.out.println("Всем привет!");



On Python:

print("Всем привет!")

Comparison table



Code compilation and execution

Interpreted language – Starts immediately, errors are detected and edited during operation

Compiled language — before starting it is necessary to convert the result into byte code, it is not possible to start the software immediately


Works slowersince the program is collected after each run

Works fasterbecause it is compiled in advance


Soft – The interpreter itself chooses the type of the variable depending on its content

Maximum severity – Each variable has its own type


Web development

Automation, administration

Machine learning

Working with big data

Scientific research

Corporate, desktop, mobile programs, software for banks, industries, technology, etc. There are practically no restrictions

Entry threshold

Lower (easy syntax)

Above (OOP and unwieldy syntax)


Both languages ​​are relevant and will remain so for decades, both universal, applicable in various fields. Python is simple, but works slower and is not used by large customers, for example, to design highly specialized software. Java is a reliable, fast, cross-platform language that will help you master object-oriented programming and guarantee demand on the labor market. But to program in Java, you will have to spend a lot of effort and time.

Subjective opinion of the author: if you don’t plan to dive headfirst into programming, and the language you’re learning is just an additional tool in other tasks (analytics, production automation, scientific experiments), then Python is perfect. It will increase your qualification many times. But those who want to connect their activities specifically with development, it is better to take up Java right away. Then it will be easier to switch to the same C+.
