As the time is changing, technologies are expanding and with that, the priority and the importance of the technical languages are also changing. So, usually, it becomes difficult to pick when we have to choose between two languages.



java vs .net


Here we will see the battle between Java and Microsoft .Net in order to make this clear which language is better to choose. For that, you may also have a quick look at this short video:

Microsoft .net and Java are two famous technologies with the help of which you can build software, websites, and web apps. As both these languages are famous in their own place, so, it usually becomes difficult for businesses to choose which language is best to choose as a primary development tool in order to create intuitive applications. With the help of both these technologies, you can create large-scale business applications.

Before doing a comparison between these two, you should know about the applications created using either of the technologies. Yes! There is no doubt that in this piece of article, we are going to do the comparison here but our main motive is to make the businesses understand which option is much better for them according to their operational requirements.

The Core Differences between Java and .NET

One of the major differences between Java and .Net is that Java, usually Java Enterprise Edition is able to work on any operating system, on the other hand, .Net is able to work only on various versions of Windows. Even if there is the availability of open-source implementations of .Net, this framework still targets Windows users.

A new thing to discover about .Net

It’s mandatory to tell you that Microsoft has just announced .Net core v3.0 which is the new and improved version of .net Framework.

One of the good advantages of an improved version of this .Net framework is: .Net core is both open-source and cross-platform.

Another major achievement of the .Net core is that it is available with the end number of new features which are really beneficial for development, web, cloud, and mobile applications.

But the reason behind why you need to understand the difference between these two is that .Net core does not support all features of .Net frameworks.

But it is always better to go for .Net core because of these following reasons:

.Net Core is an open-source software framework so it becomes easy for the enterprises and developers as well individually to build apps with it.

Unlike the .Net framework, .Net Core is a cross-platform which supports three different operating systems- Windows, OSx, and Linux.

So, these are some of the enhanced features of the improved version of the .Net framework. And keeping in consideration this individual importance of the .net framework and .Net core, let’s continue reading the main topic that is Java vs .Net.

And talking about Java, it could be said that as this language takes the help of Java Virtual Machine which basically follows the rule that code should be like that it can run on any device and under any operating system and ultimately makes proves itself as a portable platform-independent programming tool.

Here is one more major difference that is related to an Integrated Development Environment (IDE) that is mandatory for each platform. IDE is basically a software tool which is having important tools for a developer so that they can build and test software applications. For .Net applications, there is a default IDE and that is a visual studio, an amazing tool that can help to build apps.

On the other hand, there are four main IDEs for the Java developers that are available in the market and those are Eclipse, IntelliJ Idea, Oracle NetBeans, and Oracle JDeveloper.

Look carefully at the above-given stat which is researched by a famous job search site Indeed which is clearly showing that the demand of the Java developers is high in comparison to .Net developers. And job seekers are looking more for Java developer’s job in comparison to looking for .Net developers job.

However, it could be said that there is a demand for the jobs of both positions either it is .Net or it is Java. Their demand and importance could be seen according to the project in the organization.

Key features of Java vs .Net


Language Support


One of the major importance of Java is that it shares a single language across different platforms. But still, the programs written with it work independently across different OS types. Java is able to support languages like Python, Ruby, Groovy, Scala, and Kotlin.

On the other hand, .Net framework is able to support languages that are useful for backend development and web services, such as C# and C++. Presently it supports about 20 languages. With the help of this, you can program in any language according to your choices such as Vb.NET, C # .NET, Perl, and many others. But still, it is very useful for generating a particular code for the Windows platform only.

So, it could be said that .NET supports a multi-programming environment and on the other side, java is based on a single programming language that is helpful in supporting multiple.




Talking about the Java IDE, it consists of a code editor, compiler, and debugger. Eclipse, IntelliJ Idea, Oracle NetBeans, and apart from this, in order to make writing and testing of the code easier, there is an Oracle Jdeveloper that is specifically designed for this purpose. These IDEs are available with inbuilt plugins and auto-fill options with the help of which Java’s flexibility could be a boost as well as offers scope for innovation.

On the other hand, the .Net platform is available with Visual Studio which helps in editing, compiling, and run-time customization of the behaviour of APIs with the help of making use of library macros. Apart from this, there is no need for developers to evaluate the IDEs and other tools in advance.

Performance & Compatibility

There is no need for Java for conversion to Machine learning until the code gets executed. And on the other side, .Net is assembled and then run on the system. This is the reason behind it why C# works better in a runtime environment.

The older versions of Java which are older than Java7 are not able to support the easy and simplified data structure, switch case.

.Net is known for supporting switch cases for string variables in C# and native generic data. Linq (Language Integrated Query) is supported in ASP .NET but not supported in Java.


Security is always a major concern for an open-source platform like Java as there is a lack of professional support.

On the other hand, .Net is an all in all platform, so its security is the responsibility of Microsoft. It is efficient to offer all-time support to its enterprise clients.

Advantages and Disadvantages of .NET

One of the major advantages of the .Net platform is its unified environment which is offered by Microsoft. At the platform of .Net, you can find endless horizontal scalability where you can get most of the IDEs and tools within the Microsoft Developer Network.

And talking about its main disadvantage which is that the support is only available for

Overall, migration to .NET is more expensive compared to other frameworks. In this framework, the codes that are managed run slower in comparison to the native code. And for new features and enhancements, developers depend only on Microsoft.

In short, it could be said that migration to .Net is more expensive in comparison to other frameworks.

Advantages and Disadvantages of Java

One of the major advantages of Java is that it is portable, so you can easily choose the operating system according to your choice in order to build your app or website. Keeping each and everything in domain objects, Java calls the database-less often as the Object-relational support is much better.

Java apps are compatible with other platforms in a much better way with the help of using more advanced continuous integration tools like Jenkins and Travis CI. java community is strong and growing as there are various free integrating connectors that are available.

Let’s move towards focusing on the major disadvantage of Java and that is Possible security breaches because these kinds of issues are very common on this platform.

Apart from this, the functioning of Scala is not at all good with Groovy, requiring advanced software development skills. Even it is said by various developers that Java is slower in comparison to other languages because of its multi-platform nature.

Java and .NET: Which Platform to Choose

Both Java and .Net are having a little bit different features for software development whether it is about IDEs or portability. But still, both the platforms keep the same goal and target the same audience or market segments such as small business or enterprise.

So, it is a little difficult to decide which language is best for your project as both these languages are doing well in their own places and are suitable for different projects. And do not forget that whenever you will ask developers about these languages, you will get opinions based on their preferences and skills.

To cut it short, it could be said that Java is suitable for web projects, whereas the .Net framework has taken over for web services and APIs, most preferably for windows API service. Java is mostly used for Linux platforms, but still, it also runs in a Windows environment. And do you know that developers mostly avoid choosing this as it is a hard choice for them?

Final words

To sum up, it could be said that, there could not be a perfect choice between .NET and Java. It all depends on development skills, underlying infrastructure, requirements for interoperability, and end-user environments as both these platforms offer almost the same features and target the same market.

The selection between them basically depends on the requirement of the company. You can pick .Net development company for Rapid Application Development (RAD) solutions and for large-scale enterprise projects go for Java development company.

If still, you are in doubt then you can talk to .Net developers or Java developers who can solve your doubts and can consult you properly based on your requirements.
