Java vs Python: Considerable Difference

While discussing Java vs Python, the choice hinges on your project requirements, as these include unique features and capabilities. Some find Java easier, and some find Python easier, but it depends on your practice and which programming language you want to opt for.
Here, we will discuss some helpful aspects of choosing between Java and Python. Check out the following.

  • Java vs Python Popularity
Java VS Python Popularity

Considering data gathered from Statista, we can clearly see Python leading by being the second most famous programming language worldwide among software developers as of 2023 after JavaScript. As per the Survey, 54% of developers are using this programming language globally. On the other hand, Java has secured fifth position with 49%.

We can easily conclude that Python is becoming more popular than Java because of its flexibility and easy learning curve. It also has a vast community of developers who are always available to address any issue.

  • Java vs Python Speed

Python comprises capabilities such as ease of use, straightforwardness, and usability, fostering lightning-fast development. It is concise and needs fewer lines of code to reach the desired result, while Java is a statically typed language with a compiled nature. Code written in Java is compiled into bytecode, and then you can run it on JVM (Java Virtual Machine). Succinctly, both give tough competition to each other in terms of speed. If Java is considered faster, then intense working on Python interpreters closes the gap properly.

  • Java vs Python Syntax & Coding Style

Java uses a statically typed syntax that requires an open declaration of variable types and punctuation following stern rules with semicolons and braces. This results in verbose code that focuses on structure and clarity. On the other hand, Python prefers dynamic typing and relies on code chunk indentation for block structure, encouraging conciseness and readability. It has a more flexible and less cluttered syntax that is suitable for fast development and scripting.

  • Python vs Java Performance

Java is famous as an interpreted and compiled language, which makes it perform better than Python and facilitates rapid execution. Java is more suitable for high-performing applications with a Just-In-Time compiler and static typing. Python is an interpreted language that doesn’t compile its programs in advance, leading to errors in runtime and possibly a program crash. However, integrating C/C++ libraries and optimization techniques can optimize Python’s performance.

  • Java vs Python Learning Curve

Between Java vs Python, Python has a soft learning curve compared to Java as it is popular as a simple, intuitive, and easy-to-learn language for beginners. It enables newbies to write only a few lines of code with less complexity. On the other hand, Java is complex but not for those with specific experience, detailed understanding, and long-term practice. To write code in Java, one needs to have in-depth knowledge of its syntax and concepts, such as object-oriented principles and strict type definitions.

Nowadays, new programmers are challenging themselves by choosing Java as their first coding language due to its popularity and future scope.

  • Java vs Python Security

In Java and Python for security, they both offer rigorous security features. Still, Java focuses more on bytecode verification, strong type-checking, and a built-in security manager for sandboxing, alleviating vulnerability, and increasing security at the runtime level. Whereas Python is more flexible, its reliability in third-party libraries for security features makes it vulnerable to external threats. However, Python applies various methods to handle security vulnerabilities, such as dependency management, constantly updating Python packages, etc.
