What is Java?

Java is a multi-platform, object-oriented, and network-centric, programming language. It is among the most used programming language. It also used as a computing platform, and it was first released by Sun Microsystem in 1995. It was later acquired by Oracle Corporation.

History of Java

Here, are important landmarks for Java language

The Java language was initially called OAK. Originally, it was developed for handling portable devices and set-top boxes. Oak was a massive failure. In 1995, Sun changed the name to "Java" and modified the language to take advantage of the burgeoning www (World Wide Web) development business.

Later, in 2009, Oracle Corporation acquired Sun Microsystems and took ownership of three key Sun software assets: Java, MySQL, and Solaris.

Features of Java

important features of Java

• Write code once and run it on almost any computing platform
• It is designed for building object-oriented applications.
• It is a multithreaded language with automatic memory management
• Facilitates distributed computing as its network-centric

What is Python?

Python is a high-level object-oriented programming language. It has built-in data structures, combined with dynamic binding and typing, which makes it an ideal choice for rapid application development. Python also offers support for modules and packages, which allows system modularity and code reuse.

It is one of the fastest programming languages as it requires very few lines of code. Its emphasis is on readability and simplicity, which make it a great choice for beginners.

History of Python

Python language

Python was first conceived in the late 1980s, but its implementation started only in December 1989. It was invented in the Netherlands, by Guido van Rossum. Rossum published the first version of Python (0.9.0) in February 1999. It was derived from ABC programming language, which is a general-purpose programming language.

Nowadays, Python is maintained by a core development team although Rossum still plays a vital role in directing its progress

Features of Python

important features of Python

• Easy to learn, read, and maintain
• It can run on various hardware platforms & using the same interface.
• You can include low-level modules to the Python interpreter.
• Python offers an ideal structure and support for large programs.
• Python offers support for automatic garbage collection.
• It supports an interactive mode of testing and debugging.
• It offers high-level dynamic data types and also supports dynamic type checking.
• Python language can be integrated with Java, C, and C++ programming code.

Why Need Java?

• Detailed documentation is available.
• A large pool of skilled developers available
• A huge array of 3rd party libraries
• It allows you to form standard programs and reusable code.
• It is a multi-threaded environment that allows you to perform many tasks at the same time in a program.
• Excellent performance

Why need Python?

• Very simple syntax compared to Java, C and C++ languages.
• Used for Machine Learning, Deep Learning, and the general overarching AI field. Very useful in data analysis and visualization.
• Extensive library and handy tools for developers
• Python is cross-compatible
• Python has its auto-installed shell
• Compared with the code of other languages, python code is easy to write and debug. Therefore, its source code is relatively easy to maintain.
• Python is a portable language so that it can run on a wide variety of Operating systems and platforms.
• Python comes with many prebuilt libraries, which makes your development task easy.
• Python helps you to make complex programming simpler. As it internally deals with memory addresses, garbage collection.
• Python provides an interactive shell that helps you to test the things before it's actual implementation.
• Python offers database interfaces to all major commercial DBMS system.

Disadvantages of Java

Here, Java language

•  JIT compiler makes the program comparatively slow.
• Java has high memory and processing requirements. Therefore, hardware cost increases.
• It does not provide support for low-level programming constructs like pointers.
• You don't have any control over garbage collection as Java does not offer functions like delete(), free().

 

Disadvantages of Python

Here, Python language

•  Used in fewer platforms.
• Python is interpreted, so it's much slower than its counterparts.
• Weak in mobile computing, hence not used in app development
• Science Python is dynamic, more errors show up at run-time
• Underdeveloped and primitive database access layer
• Absence of commercial support

Parameter	Java	Python
Compilation	Java is a Compiled Language	Python is an Interpreted Language
String operations	Offers limited string related functions.	It offers lots of string related functions.
Multiple inheritances	Multiple inheritances is partially done through interfaces.	It offers both single and multiple inheritances.
Speed	Java program runs slowly compared to Python.	Python programs run faster than Java.
Best features	• Great libraries • Widely used • Excellent tooling • Huge amount of documentation available	• Readable code • Rapid development • Beautiful code
Static or Dynamic	Java is statically typed	Python is dynamically typed
Portability	Any computer or mobile device which is able to run the Java virtual machine can run a Java application	Python programs need an interpreter installed on the target machine to translate Python code. Compared to Java, Python is less portable.
Architecture	Java Virtual Machine provides the runtime environment to execute the code and convert bytecode into machine language.	For Python, the interpreter translates source code into machine-independent bytecode.
Backend Frameworks	Spring, Blade	Django, Flask
Famous companies using this technology	Airbnb, Netflix, Spotify, Instagram.	Uber, Technologies, Dropbox, Google.
Machine Learning Libraries	Weka, Mallet, Deeplearning4j, MOA	Tensorflow. Pytorch.
Best use for	Java is best for Desktop GUI apps, Embed Systems, Web application services, etc.	Python is excellent for scientific and numeric computing, Machine learning apps, more.
Database support	Java offers stable connectivity	Python offers weak connectivity.
Code example	class A { public static void main(String args[]){ System.out.println("Hello World"); } }	Hello World in Python: print "hello world";
Salaries	The average salary for a Java Developer is $103,464 per year in the United States.	The average salary for a Python Developer is $118,626 per year in the United States.

Java or Python: Who is the best? 

Python is an ideal choice for beginners as the language is more intuitive, and its syntax is very much similar to the English language. Its open-source nature facilitates a slew of new tools that improve it. On the other hand, Java is a general-purpose programming language that was designed with a specific goal of allowing developers to write once run anywhere. 

 Selection one language among these ultimately comes down to the nature and the cost of the development project.
