Dot Net vs Java – Important differences 


.NET (pronounced as dot net) and Java are the two main and most important software developing  technologies in today’s world, but ever wondered what roles do they play in the technological world individually, that has increased their demand so much in the market and made them one of the leading technologies in today’s world.


If Not, then let’s know some detail aspects of them and their uses + what roles do they play.


You all must be aware about Netflix, Google, Instagram , Snapchat, LinkedIn, Spotify, Alibaba, eBay, Myntra and many more applications like them, but ever wondered how are they developed and the basic principals that lie behind in their development? 


No? Then let’s know


The answer for the above question is much familiar and very well know to most of us, that is JAVA.


Java is a very popular programming language which is used various companies (including the ones mentioned above) throughout the world. These all companies make use of java to develop such software applications and run them. It is an open source language which is used by plenty of developers as it is much convenient and really easy to develop a software.


Whereas intel, GoDaddy, Fujitsu, Microsoft, Dell, Stack Overflow and many other companies uses .NET framework which is used to develop end-to-end applications.


.NET unlike Java is not a programming language but a  framework which comprises a bunch of tools like many different programming languages, libraries, IDEs and etc.


*    Dot NET can support multiple languages like cobra, C#  F# etc.,


So, here are some of the criteria under which these two can be distinguished:-

  • Foundational differences
  • Portability
  • IDE and tools both of them use
  • Efficiency or productivity of both of them, and
  • Languages they support

1. Foundational differences between Java and .NET:-


Java is a programming language which helps to develop a software application. It is known as “write only once read anywhere coding language” due to its benefit of writing it once and run it anywhere.


Some other features include:-

  • Object-oriented language
  • Portable
  • Compatibility between various versions, and
  • Security

Whereas .NET is an entire framework which comprises multiple languages and other tools by which it allows us to develop end to end applications.

  •  It is:-
  • Robust 
  • Reduces memory leaks
  • Secure, and 
  • Creates a manageable environment

2.Portability :-

Java can work on different operating systems or in multiple environments as java uses specific JVM for Windows, Linux, Mac and etc. Hence, once a written code can be executed in any of the operating systems.


While DOT NET works on only different versions of windows. You can’t access  DOT NET anywhere else until and unless you’re working with .NET core.


3.IDE and tools used by both of them:-

Java works with some famous default IDEs that are

  • Eclipse
  • IntelliJ
  • Oracle
  • Net beans etc.

Whereas in .NET the default IDE used by people is Visual Studio Code as it is integrated in .NET.

 These IDEs provide a single workspace where one can perform a lot of tasks and can even take in use the querying feature of  Dot NET.


4.Efficiency and Productivity of both of them:-


There are multiple factors which play roles in the efficiency of both them. 


Java is an interpreted language which gets converted into machine language only after the code is written.


Whereas in .NET the code is compiled and run where the code is initiated on the system i.e., you can use the code only where you’re creating the code.


These factors play a major role in both of these technologies.


5.Language support:- 

Since java itself is a language so it does not support any other language but if we talk about JVM (java virtual machine) which is a virtual machine that enables the system to run programs written in other languages that are assembled to java byte code.


So, java can support languages only through JVM.


Whereas .NET which ain't a language but a framework because of which it supports multiple languages.


.NET supports around 20 languages among which most popular ones have been listed below:- 

  • C++
  • C#
  • F#
  • VB.NET
  • Cobra etc.

There are vast career opportunities in the future for freshers as these technologies store great potential in them. They are open to a number of new and beneficial career options in the near future. The changing nature and shift towards technology are raising big opportunities for software developers.

Some of the job trends for both of them have been listed below:-


Java job trends


Junior java developer:-

  • The average income in America as a junior java developer -  $56,000 per annum  

  • The average income in India as junior java developer - ₹ 4.5 LPA 

Senior java developer:-

  • The average income in America as a senior Java developer - $ 101,000 per annum8

  • The average income in India as a senior Java developer - ₹ 9.28 LPA 
  • (Income increases as per experience)


.NET job trends


Junior .NET developer


  • Average income in America as a junior .NET developer - $ 61,000 per annum
  • Average income in India as a junior .NET developer - ₹ 4.1 LPA


Senior .NET developer


  • Average income in America as a senior .NET developer - $ 96,000 per annum 
  • Average income in India as a senior .NET developer - ₹ 8 LPA 

(These are average figures so you may earn more or less depending on your skills and experience or the company you’re applying to.)


Which one is better DOT NET or JAVA ?



This is a tricky question as both the technologies hold equal potential and are good as per their aspects. Both of the developing software is used by various companies in developing multiple applications. 


So, the choice of being a Java developer or a Dot NET developer totally depends on oneself or the company s/he is interested in. 


Taking into consideration the company's choice and other factors, one can choose easily choose and prefer the suitable one.


In Conclusion, irrespective of the choices you make, they both hold equal and good opportunities for an individual to set a career.
