Python is comparatively slower than Java because it’s an interpreted language. The early 2010s were Python’s golden years when it started gaining prominence as a cross-platform language across Windows and Microsoft.
Yet, Python hasn’t been as successful in developing mobile applications as Java. Hence, Java soon became the preferred choice due to its object-oriented, cross-platform, and easy-to-learn nature.
However, even though Java had a successful debut in its path to success, is not as easy to learn as Python. For the same reason, Python has maintained its first-place position in the TIOBE Index for two straight years, while Java shifted to fourth place.
Java is a general-purpose, object-oriented programming language originally developed by James Gosling at Sun Microsystems and later acquired by Oracle in 1995. The intention behind developing Java was to “write once, run anywhere” (WORA).
Java can run on any Java Virtual Machine (JVM) as it is compiled using bytecode and statically typed. Since it doesn’t need to be compiled to a specific platform machine, it’s platform-independent.
Java’s syntax is similar to C++ and C but has fewer lower-level facilities. It has emerged as a popular choice in the Java vs Python debate for web development due to its efficiency in handling asynchronous programming, Desktop GUIs, enterprise solutions, and embedded systems.
Java has emerged as a recognized and powerful language for enterprise web application development. It can convert directly into machine code, making it easy for Java developers to execute it. Here are some notable features of Java development services:
Developers find it easy to work with Java because of its strict syntax, which requires semicolons and curly blocks to write code blocks.
Java also creates a structured approach for reducing type errors before executing a program because of its static type system.
Java creates a new class by inheriting features from existing classes, performs the same actions in different ways, and integrates variables & code in a single unit.
Java helps developers perform multiple tasks simultaneously with built-in multithreading support, powerful synchronization, and the ability to extend a Thread class.
Java’s top position continues for the 8th year in a row. Its ability to compile code in bytecode into the native machine with Just-in-time (JIT) compiler makes it a worthy opponent.
Let’s discuss Java’s pros and cons to help you answer the following question: Is Java better than Python?

Build Future-ready Apps
Java code can run on any application and is easier to port and execute on any platform. On the other hand, Python is simpler and accelerates the development process, enabling easy prototype building.
The dynamics of both languages exhibit notable differences in scenarios where speed is a critical factor for developing a project. Other differences range from creating arrays to making code run efficiently. Let’s discuss these differences in detail:
Python’s popularity has increased the chances of hiring Python developers by 50% since 2023 in the highly acclaimed TIOBE index. It is enjoying its position due to its simplicity and versatility of coding and its venture into AI and ML.
In contrast, Java has robust solutions and resources and continues its legacy. However, Its popularity has declined since the introduction of the paid license model after the Java 8 release.
Java and Python both have unique syntaxes and a rich history of utility for web development. However, their rules for defining what each symbol signifies are different.
Python ditches using semicolons and brackets, which brings more code clarity, coupled with the indentation styles. Java, on the other hand, has static typing, making the declaration of variables compulsory. With OOP, hiring Java developers provides robust web apps, back-end development, and Android mobile apps.
Coding efficiency in both languages is crucial for writing clean code. Java excels in building applications that require high performance, allowing developers to upgrade their code error-checking capabilities and code optimization.
Python is best for projects that require higher development speed, such as building prototypes and web applications using powerful frameworks like Django and Flask.
Java and Python both have specific libraries that enhance productivity, simplify complex tasks, and enable developers to solve problems by bringing in innovation. Python’s vast range of libraries includes Django and Flask for web development and Pandas and NumPy for data science.
Similarly, Java’s boastful library includes comprehensive support for web development through Spring and Hibernate.
Java Database Connectivity (JDBC) uses a Java API to connect databases, making it easier to send queries and update data. It also has a Java Persistence API (JPA), which provides an Object-relational Mapping (ORM) approach to connecting database objects.
Python supports a large set of databases through its numerous APIs and ORMs. Common ORMs include SQLAlchemy and Django. The Python Database API (DB-API) provides easier database connectivity with Python code for building consistent interfaces for the backend.
Both Java and Python have their own frameworks and paradigms to offer robust back-end applications with OOP’s structured approaches. Python’s back-end frameworks include Django and Flask, whereas Java utilizes Blade and Spring back-end frameworks.
Django works on the Don’t Repeat Yourself (DRY) principle to reduce code lines and enhance readability with indentation. Java’s Spring gives tough competition to Python’s comprehensive programming and configuration model Django for modern enterprise-based applications.
Similarly, Python’s Flask is a minimalist Python framework for smaller Python programs for better component control. Its counterpart, Java, has Blade as a lightweight framework for building fast and scalable applications with fewer boilerplate codes.
Python and Java both have an extremely different approach to developing modern applications. Python has dynamic typing as compared to Java’s static typing. The most significant difference in both of these types is how developers write, design, and troubleshoot problems in code.
Let’s understand the difference between their syntax through an example of code:
Python doesn’t require developers to input variables since they are input during runtime. Hence, Python is clear, uncomplicated, user-friendly, and intuitive as it eliminates the enclosed brackets and replaces them with indents.
The code below shows how Python requires only two lines of code when compared to taking ten lines of code from a file in Java.
Demo= [“I am a Designer”, 8]
For i in Demo:
Print (i)
Source
Dynamic typing in Python allows developers to define a variable at runtime, saving them the need to specify the variable’s data type when declaring it.
Java requires developers to type in all the variables due to a rigorous syntax. So, if an error occurs in the code, the program might not run, making it complicated for beginners. Developers would need to input code lines inside the curly brackets to execute a code block.
Here’s an example of code lines in Java.
Public class Demo{
Public static void main (string args [ ]) {
String array [ ] = {“I am a Designer”, “6”};
For (String I : array ){
Systm.out.println(i);
}
}
}
Since Java has static typing, developers have to determine the variable while compiling. It compels developers to specify the data type of a variable when declaring.
Java is a highly efficient programming language with powerful memory management. With extensive library support, Java is ideal for web applications. It can seamlessly work with frameworks like Servlet API, JDBC API, and Java Enterprise Edition (JEE).
Here are some ideal use cases where you should use Java over Python for development:
Java’s JDBC is ideally suited for enterprise applications where transaction processing and management are essential for handling large datasets.
Java is a good choice for cross-platform applications on Windows, Linux, and Mac. Moreover, it powers Android application development because it is backed by Google in Android Studio.
Lastly, building high-performance back-end applications needs Java’s performance-oriented architecture to manage real-time inventory data.
Java has numerous libraries like Deeplearning4j, Weka, JSAT, and MOA, which makes it a preferred option for building applications requiring ML and data science tasks.
Java is a suitable language for developing games on Android, PCs, and consoles with game engines like Litiengine, GreenLightning, libGDX, and JMonkeyEngine.
Java’s performance can be best leveraged in financial analytics, where scientific computing speed is essential for high-performance computing.
Python’s dynamism makes debugging easy and encourages the rapid development of application prototypes in various fields. Its powerful libraries, frameworks, and data structures make it a performance-driven development language for varied use cases.
Python creates robust and scalable web applications using common back-end logic with frameworks like Django, Pyramid, and Flask.
AI is a complex field that is simplified with this general-purpose language, which has built-in libraries, requires less coding, and supports deep learning, image recognition, and data processing.
Python makes it easier to connect hardware and software by implementing the business logic at the device level with Raspberry Pi to turn normal objects into smart devices.
Front-end development is easier with Python, which allows you to develop rich GUIs with the Tkinter library and toolkits like KIVY, PyGUI, and PyQT.
Operating Systems
Python, coupled with the C programming language, develops high-performing operating systems with easy-to-read syntax. Popular examples include Ubuntu’s Ubiquity and Red Hat’s Fedora.
Python’s scripting helps write scripts by generating sample inputs for application testing, scraping website and blog content, and automating emails with Salt, Fabric, and Ansible.
For a long time, Python’s rival was another general-purpose programming language, Perl. As time evolved, Python grew in importance, becoming a niche language for a very narrow set of applications.
An early riser in setting its path to success, Java gained support from powerful companies like Sun Microsystems and Oracle.
Python’s power lies in its ability to adapt to the current market needs of working with Big Data with its unbeatable ML tools.
Python’s text-to-image generation and chatbot development in AI, such as DALL-E and Google’s LaMDA, have made other languages, especially Java, struggle to compete.
With the release of Python 3.11, it’s set to break all its speed barriers by predicting the types and values, offering a 10-60% increase.
However, multithreading still remains an issue with its Global Interpreter Lock (GIL). Compared to Java, multithreading is easier in Java, where developers can work on multiple tasks at the same time.
Python’s shorter syntax, an ecosystem of over 2,00,000 packages, and competing JDKs give it an edge over Java’s limited repositories and tedious code writing.
Python has passed the test of time from the era when proprietary code existed more than open-source code. In the current age, where more than 80% of code is open-sourced, decentralized, and needs speed, Java feels outdated compared to Python.
