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.

In this Java vs Python tutorial, you will learn:

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 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.

History of Python

Here, are important landmarks for 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

Difference between Java and Python

Here, are the main differences between Java and Python

Parameter Java Python
Compilation Java is a Compiled Language Python is an Interpreted Language
Static or Dynamic Java is statically typed Python is dynamically typed
String operations Offers limited string related functions. It offers lots of string related functions.
Learning curve Complex learning curve Easy to learn and use

Disadvantages of Java

Here, are cons/drawback of using 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, are cons/drawback of using 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

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.
