If you need help in choosing between these two programming languages for your projects, whether Java or Python is better for use, this article helps to enrich your knowledge about both, and then proceeds to see the differences between them to determine which one to use for the project.

What are Java and Python?

Python:

Python is a high-level, general-purpose computer language developed to support a simple, clear, yet concise syntax that emphasizes code readability, utilizing space rather than brackets to define a writable block. It was developed by Guido van Rossum, released to the public in 1991, and is an open-source, interpreted language that supports multi-paradigm programming.

Key features:

Readability: Python’s philosophy emphasizes code readability, making It a good language to learn from scratch.

Versatility: It is considered a general-purpose language, meaning it can be used to perform tasks beyond the specific problem sets.

Large Standard Library & Community: Python has a rich selection of existing standard modules & packages, which reduces the need for developers to write code from scratch on many common operations. It also has a large number of developers in its user communities.

Cross-Platform Compatibility: Python programming can be executed on different platforms such as Windows, macOS, and Linux with minimal modifications.

Dynamic Typing: Programmers do not have to declare variables. The data type will be regarded at runtime, and this makes the development process faster.

Java:

Java is a popular, object-oriented programming language and computing platform recognized for its ability to provide “Write Once, Run Anywhere” (WORA) capability, which means code can run on any device with a JVM(Java Virtual Machine). Developed by Sun Microsystems in 1995, it is widely employed for developing a wide range of applications, from mobile apps, for example, Android, and web applications to enterprise software, big data, and cloud services. All thanks to its security, reliability, and platform independence.

Key Features:

Object-Oriented: It enables the application of code organization into reusable classes and objects, hence it helps in modularity and gives scalability to software.

Platform Independent: WORA – It gets compiled to bytecode that runs on any JVM, not specific hardware.

Robust & Secure: Features include automatic memory management through garbage collection and strong exception handling, making it a reliable system.

Rich ecosystem: It comes with extensive standard libraries, frameworks, and tools that can easily power complex development.

Differences between Java and Python

Applications of Java and Python:

Java:

Mobile Applications:

Java is the leader in mobile development because Android heavily relies on the programming language for development. Besides being compatible with frameworks such as Kotlin and Android Studio for seamless development, the job market also focuses highly on the language.

Java ME(Micro Edition) can run applications on multiple devices because of its cross-platform feature.

The versatility of the platform can be noted by the fact that the Java ME version

Features:

• Supports the development of compatible mobile applications

• Integrates with Android Studio and Kotlin.

• Offers scalability for sought-after applications.

Web-based Applications:

Java reduces the burden in web application development through the use of servlets, JSPs, and Struts. Moreover, it facilitates the development of secure web applications as well. E-commerce sites such as Broadleaf have also been built using the language.

Features:

• High security of a web application.

• Simple coding using Servlets and JSPs.

• Framework support for e-commerce apps.

Gaming Applications

Java is very helpful in creating games as it simplifies the development of games. Also, Java can be used with 2D or 3D gaming engine development packages like jMonkeyEngine.

Features:

• Very good support for both 3D or 2D
• Compatible with jMonkeyEngine
• Efficient handling of real-time multiplayer

.

Python:

Machine Learning and Artificial Intelligence

Machine learning and Artificial Intelligence are two of the hottest topics today. Python and its built-in library tools aid in the implementation of AI and ML algorithms. Further, it also helps to have simpler, concise, and easily-readable code, which is highly advantageous for developers who can effectively create complex programs easily. Further, there is a nice flexibility to the programming language. To name a few of the built-in library tools to aid AI and ML processes:

• NumPy for Complex Data Analysis

• Kera’s for Machine learning

• SciPy for technical computing

• Seaborn for data visualization

CAD Applications:

CAD stands for Computer-Aided Design. It is the process by which 3D as well as 2D designs are created iteratively. This method has replaced the traditional method of drift. This method has been made possible in the smart language Python, in which unbelievable applications are embedded, such as Blender, FreeCAD, Open Cascade, etc., for the purpose of designing a product in an efficient manner.

Business Applications

Many security and scalability features in Python provide it an advantage in implementing high-speed business solutions. Some of the built-in libraries and tools include:

•Odoo is a business management tool that offers you an automated solution to your business processes.

•Tryton: Tryton is open-source business software that is highly usable. Its integrated features include financial accounts, sales, CRM, purchases, and many others.

Performance and Scalability of Java and Python:

Speed and Efficiency:

Java is faster than Python as it is a compiled language, and Python is an interpreted language, meaning Java has to be compiled before executing it, while Python code is executed directly without compilation, which can result in problems at runtime.

Memory Management

Java has an edge over Python in managing memory because Java uses a garbage collector to delete any object that is no longer needed or that has no references or links to it. Though it uses a garbage collector too, it is less efficient in doing so than Java.

Parallel Processing

Python is more favorable in terms of parallel processing. “Multiprocessing,” a module in Python, enables parallel processing. Parallel processing in Java is more complicated as it requires more code.

Handling Large Datasets

Python is better than Java at handling large datasets. Python has libraries like NumPy and Pandas specifically designed for handling large datasets, while Java does not have a similar library.

Java is better suited for complex and large-scale applications, while Python is better for data analysis, scientific computing, and machine learning.

Use cases and industry applications of Java and Python:
