Python vs Java: Which is Better?


If you compare Python vs Java, you will find that both have unique features that help different sections of the software development industry. 

You can develop Web Apps and Software with Pythonbuild AI/ML solutions, Develop Games, Blockchain solutions and much more. Likewise, you can build Web and Mobile Apps with Java,  build IoT and Cloud Applications, develop Enterprise applications and many more.  

Both Java and Python are general-purpose object-oriented and extensively utilised in developing various types of internet-based apps. If the comparison of Python vs Java is about who came first, then Java will win the race. Python was created and made publicly available in roughly 2000, whereas Java was launched earlier.


To judge the comparison of Python vs Java, we will have to look at several factors such as speed, scalability, machine code, security, simplicity, syntax, and their usage around different technologies.


Python vs Java: Definition

What is Python?

Python is a general-purpose programming language with dynamic typing. Python’s early development took place at a Dutch research institute. Its syntax is legible and simple. The syntax was inspired by Algol68, Pascal, and ABC.

Its built-in data structures with dynamic typing, binding and lower maintenance cost make Python a good fit for Rapid Application Development.

One of the advantages of Python is that the interpreter and resource library are both freely available on the internet.

What is Java?

Java is a general-purpose, statically typed, object-oriented, and concurrent programming language. With the aid of the Java Virtual Machine, Java was designed to be a WORA (write once, run everywhere) language, able to execute on any platform and with as little dependencies as feasible (JVM).

Python vs Java Differences

Python and Java are leading programming languages in the tech industry. Some technical comparisons will clarify how they vary. The following are differences between Java and Python are listed below.

Python vs Java Performance

Python is an interpreted language that focuses more on simplicity and readability. But it has slower performance than Java because of its interpreted nature and dynamic typing. 

Java is a compiled language. It focuses more on performance and scalability. It is faster than Python due to its static typing and just-in-time (JIT) compilation.

The differences between Python and Java can be rather considerable at times. In comparison to Python, a simple binary tree test can execute 10 times more quicker in Java.

Python vs Java Syntax

Python focuses on simple and more concise syntax compared to Java. Python uses fewer lines of code to accomplish the same task as compared to Java. These make Python more user-friendly and straightforward to read.

Python uses indentation to denote code blocks while Java uses braces. Python follows dynamic typing but Java has a static typing system. Python supports functional programming paradigms while Java follows an object-oriented programming style.

Code Readability

Python strongly focuses on code readability. It has a simpler and more concise syntax compared to Java. It uses indentation to denote code blocks to improve code readability. 

Python also supports English-like syntax and naming conventions. It gets easier for developers to understand code. Java has a more complex syntax with more verbose code and requires more lines of code to accomplish the same task.

Python vs Java Popularity

According to the Stack Overflow Developer Survey 2022, 43.51% of professional developers use Python while 33.4% of professional developers use Java. According to the survey, Python ranks 4th while Java ranks 6th. 

Python’s popularity is due to its ease of use, versatility, and huge applications in data science and machine learning. Java’s popularity is due to its use in enterprise-level applications.

Python vs Java Jobs 

Python is popular in machine learning, data science, web development, and scripting. Python jobs are available in tech startups, scientific research, and education sectors. 

Java is widely used for enterprise applications, Android app development, and building large-scale systems. Job opportunities for Java are abundant in the finance, healthcare, and government sectors. 

Both Java and Python have a wide range of job opportunities but in different industries.

These are just a few examples, as the job titles for both languages can vary depending on the industry, company, and specific job responsibilities.

Python vs Java Usage in Machine Learning

You can use Python and Java in machine learning but Python is the more popular choice. Its ease of use and availability of numerous open-source libraries and frameworks such as TensorFlow, Keras, PyTorch, and Scikit-learn makes it easy for developers. Python’s dynamic typing, simple syntax, and strong support for functional programming make it an ideal choice for machine learning.

Java is less popular in the machine learning community. Java is used for developing enterprise-level applications with robust features.
