Python vs Java in 2024


Python and Java have been two of the most popular and widely used programming languages for over two decades. As we enter 2024, both languages continue to evolve and carve out important niches in software development. But which language reigns supreme in 2024? Python and Java have distinct strengths and weaknesses that make them suitable for different types of projects and development needs.

History and Origins


Python was created by Guido van Rossum in 1991. It was designed to prioritize code readability and to enable rapid application development and prototyping. Python has a gentle learning curve compared to other languages. Its high-level data types and dynamic typing allow beginners to become productive quickly. But Python also has powerful object-oriented and functional programming capabilities for large-scale software engineering.


Java was created at Sun Microsystems in 1995, led by James Gosling. The key design goals were portability across platforms and devices, performance, and enterprise application development. To achieve portability, Java code compiles to bytecode which runs on the Java Virtual Machine (JVM). This abstraction layer comes at a cost to startup speed. However, the JVM enabled Java to become ubiquitous across everything from servers to Blu-ray players.

Current Popularity and Usage

Both languages continue to grow in popularity and usage, though they tend to excel in different domains.


Python’s simplicity, extensibility, and vast collection of statistical and data analysis libraries have fueled its adoption for applications like:

It’s also widely used by programmers to automate everyday tasks.


Java powers much of the backend infrastructure for enterprise applications. Its performance, security capabilities, and cross-platform support make Java a default choice for: 

  • Enterprise resource planning (ERP)
  • eCommerce platforms
  • Android mobile development
  • Banking and Finance

Java remains pervasive across industries from healthcare to aerospace engineering.

Technical Differences

Some key technical differences underly the strengths of Python and Java in various domains.

Simplicity and Readability

Python prioritizes code readability using indented syntax without brackets, which resembles everyday English. Java uses curly brackets and requires more verbosity to access functionality and declare variable types. This results in a much gentler learning curve for Python vs the stricter, more complicated syntax of Java.

Performance and Scale

Java’s compile-time type checking and optimized JVM byte code allow it to execute code faster at scale. The JVM utilizes parallelism and just-in-time (JIT) compilation for further optimization. Python tends to prioritize developer productivity over raw performance. It is dynamically typed and interpreted at runtime, making it easier to prototype but slower for CPU-intensive programs.

Ecosystem and Libraries

Both languages benefit from rich ecosystems of open-source libraries and frameworks. Java bytecode portability enables widespread reuse of libraries across JVM platforms and versions. Python’s centralized package index PyPI contains over 250,000 packages spanning every discipline, with comprehensive docs enabling easier discoverability than Java frameworks.

Development Experience

Code Volume and Speed

Java requires more code, boilerplate declarations, and ceremony due to its verbosity. Python emphasizes brevity and allows faster development cycles. For smaller applications with limited developer resources, faster prototyping in Python delivers business value quicker at a lower cost.

However, Java’s strict typing makes it more scalable and suited for larger code bases and developer teams. The verbosity also aids long-term maintainability.

Platform and Device Support

A major advantage of Java is the JVM, which enables Java code to run on any device with JVM support – everything from servers, desktops, and mobile phones to embedded systems like smart TVs. Python runs natively on more platforms like Linux and Windows but needs recompilation to run on different architectures.

However, Python compatibility with GPUs made it the language of choice for accelerating machine learning workflows. Java GPU support is still emerging.

Future Outlook

Both Python and Java are expected to continue experiencing widespread usage and growth.

Python’s popularity will continue rising as data science and AI achieve widespread enterprise adoption. Python will dominate scripting, data engineering, cloud infrastructure, and web services.

Java will maintain its grip on large enterprise backend infrastructure and mobile development, though Python makes backend inroads. The performance gains from Project Panama and Project Loom will help Java stay competitive.

In summary, while both continue leading development language adoption, Python thrives in data science, research, and web services while Java dominates enterprise applications. Rather than a “winner takes all” outlook, each language will evolve to fill indispensable niches.


In 2024 and beyond, Python and Java will continue thriving as two of the most widely used programming languages globally. Although they have distinct differences in syntax, capabilities, ecosystem, and best-use cases, the choice between Python vs Java depends largely on the specific needs and preferences of development teams.

As data science and cloud-native development gain more enterprise traction, Python’s simplicity, versatility, and machine learning prowess ensure its ascendance continues. Meanwhile, Java remains the bedrock for backend infrastructure powering essential business applications thanks to optimized performance and rock-solid tooling.

Ultimately there is space for both languages to co-exist rather than compete directly. Developers can harness the strengths of Python for rapid prototyping and analysis while tapping into Java’s scalability for complex business logic and systems programming. Both languages will evolve to enable innovative software development solutions for decades to come.


Is Python going to replace Java?

Unlikely that Python replaces Java entirely. Java powers much critical enterprise infrastructure that Python cannot easily displace due to Java’s maturity, optimization, and enterprise tooling. Python adoption will continue rising but mostly in areas related to data analysis and science.

Which pays better Python or Java?

On average Java developers are paid higher globally. However Python skills specifically for machine learning, data science, and AI attract high salaries at many tech firms exceeding those of Java developers. Overall the compensation difference is modest and offset by Python’s faster growth.

Is Java hard to learn?

Java has a steeper initial learning curve than Python. The strongly typed syntax with classes, access modifiers, and helper functions takes time to get used to. But with practice, Java is very teachable. The effort pays dividends for large enterprise code bases. Many universities start students with Java as a first language.

Which is more popular for web development?

Python is currently more popular for web development thanks to user-friendly frameworks like Django and Flask. Java web ecosystem is complex with many competing frameworks. However, Java’s performance and scalability make it ever-present on backend infrastructure supporting modern web services.

Which language is most in demand?

Python developer hiring demand has exceeded Java in recent years, driven largely by data science/ML jobs. But Java remains indispensable for enterprise IT, enjoying steadily rising demand. Overall demand is growing for both languages according to all industry forecasts.
