    Java vs Python – and what to choose

    The Differences between Java and Python

    Let’s bullet it down here.


    • Compiled and interpreted, which means you need to compile the code before you can run it and you run it in a Java virtual machine to run it.
    • Has static types, which means you need to define the data types of variables.
    • Runs on anything that can run a Java virtual machine, which makes it good for embedded systems, like Android.


    • Python is an interpreted language, it runs with the Python interpreter but no compilation is needed.
    • Has dynamic types, which means variables can change at run time and you don’t need to define them.
    • Python needs an interpreter installed on systems, which makes it less portable.
    Java vs Python

    What is the strength of Java?

    Java is a popular programming language with several strengths that make it a favorite among developers. Some of its strengths are:

    1. Platform Independence: Java is platform-independent, meaning it can run on any device or operating system, including Windows, Mac OS, Linux, and others. This is because it runs on the Java Virtual Machine (JVM) that translates the code into machine language, making it portable.
    2. Object-Oriented Programming: Java is an object-oriented programming language, which means it supports the concept of classes and objects. This makes it easier to write and maintain large-scale applications and promotes code reusability.
    3. Large Community and Rich Libraries: Java has a vast community of developers who contribute to its growth and maintenance. This community has developed several libraries and frameworks that make it easier to build complex applications quickly.
    4. High Performance: Java is known for its high-performance capabilities due to its Just-In-Time (JIT) compiler, which optimizes the code at runtime.
    5. Security: Java is one of the most secure programming languages, with built-in security features that protect the application against threats such as viruses and hackers.

    Overall, Java’s platform independence, object-oriented programming, large community, rich libraries, high performance, and security make it a versatile and powerful programming language suitable for a wide range of applications.

    What is the strength of Python?

    Python has numerous strengths that make it one of the most popular programming languages today:

    1. Easy to Learn: Python is known for its simplicity and ease of use, making it an ideal language for beginners to learn. It has a readable syntax and a large community of developers who offer support and resources.
    2. Versatility: Python can be used for a wide range of applications, from web development and data analysis to artificial intelligence and machine learning.
    3. Large Standard Library: Python comes with a large and comprehensive standard library, which makes it easy to perform tasks like file handling, network programming, and database access.
    4. Cross-Platform Compatibility: Python is compatible with most operating systems, including Windows, Linux, and macOS, making it a versatile language for developers.
    5. Third-Party Libraries and Frameworks: Python has a large number of third-party libraries and frameworks that extend its functionality and allow developers to build complex applications quickly and easily.
    6. Strong Community: Python has a large and active community of developers who contribute to its development, create useful libraries and tools, and provide support and resources for other developers.

    Overall, Python’s strength lies in its simplicity, versatility, and ease of use, which makes it an excellent choice for both beginners and experienced developers.

    Should you choose Java or Python?

    Choosing between Java and Python ultimately depends on your project requirements, existing knowledge, and personal preference. Here are some general guidelines:

    Choose Java when:

    • You need to build large-scale, complex enterprise applications
    • You need high performance and low latency
    • You need strong type checking and static analysis
    • You have experience with object-oriented programming
    • You want to build Android mobile applications

    Choose Python when:

    • You need to develop web applications, scientific computing, data analysis, or machine learning projects
    • You prioritize ease of use and readability
    • You prefer dynamic typing and a more flexible syntax
    • You are working on a small to medium-sized project or building a proof-of-concept
    • You have a background in scripting or data analysis

    Ultimately, both Java and Python are powerful languages with extensive libraries and communities. It’s important to consider the specific needs of your project and the strengths of each language before making a decision.

    I would still challenge some of the commonly considered strength of Java. Python is used to build large-scale, complex enterprise applications. Python has type checkers, this ensure that variables are just like static types.

    Why is Python is growing in popularity

    Python has been called not a real programming language by many. Including me in my dark past.

    That said, for the most part, the critique of Python is often rooted in ignorrance.

    But before diving into that let’s look at a few benefits that makes Python popular.

    1. Easy to Learn and Use: Python is a beginner-friendly language with a clear and concise syntax that is easy to understand and learn. This makes it accessible to a wider range of people, including beginners and non-programmers.
    2. Versatility: Python can be used for a wide range of tasks, from web development to data analysis, machine learning, and scientific computing. This versatility makes it a popular choice for many different industries and use cases.
    3. Large and Active Community: Python has a large and active community of developers who create and maintain libraries, frameworks, and tools that extend the functionality of the language. This community also provides a wealth of resources, including documentation, tutorials, and support.
    4. Data Science and Machine Learning: Python has become the de facto language for data science and machine learning due to its powerful libraries such as NumPy, Pandas, Scikit-Learn, TensorFlow, and PyTorch, which provide efficient and scalable solutions for data analysis and machine learning tasks.
    5. Rapid Prototyping and Development: Python’s ease of use and large library ecosystem makes it ideal for rapid prototyping and development. Developers can quickly build and test ideas, iterate on them, and deploy them to production environments.

    A few critque points rooted in ignorance.

    • Python doesn’t have static typing and will crash at run-time. While this is true, it has ways to make static type checking before running the code.
    • Python cannot be used on large enterprise web applications. While this used to be true, new frameworks have made it possible to craft cloud components that can scale up and down on demand by infrastructure.
    • Python is slow. While this is true, a lot of frameworks and libraries are written in C/C++ where the actual computing is done. 80% of the time of the program is spent in 20% of the code, and luckily, that seems to be easy to write libraries for this 20%.
    • Python uses indentation. Some claim not to trust that. I don’t really see the point in this.
    • Python is not as secure as Java. Both Python and Java are considered to be relatively secure languages, and security largely depends on how the language is used and the practices followed during development. The primary weakness Python is pointed at is that it is weakly typed, but as pointed out above, you can do pre-checks before running the code.
    • You write better code from scratch than using libraries. The best libraries are written by specialists that are among the best in that field. Why not let them do what they do best, and you do what you want, instead of trying to make your solution the same?
