Java vs .Net – Key Differences to Decide Which is Better?


Programming languages have changed with time and as a result, the code industry is changing, Java and .NET are certainly among the wider technologies influencing the trend. Today, they are used by companies for server-side applications. But the developers struggle in Java vs .NET choice.

Both Dot NET and Java focus on providing the landscape for large-scale applications. But Java vs. .NET is the question that needs an answer, so we’re to help you. We will take you through Java and .NET differences, to help you choose for your website or app development.

Meanwhile Dot NET and Java may seem similar, but differences between Java and .NET arise in the platform and execution process.

Firstly, both Java and .NET can be an ideal framework, but only .NET stands true to its meaning. Dot NET is a framework whereas Java is a programming language. Java is operating on object-based, class-based, and general purposes.

Secondly, Java Enterprise Edition (JDE) works on every Operating System. Whereas dot NET operates on various versions of windows.

Thirdly, dot NET’s functionality is based on a limited number of open source codes. However, its capability to work on all Windows platforms makes it an asset for the developers. But the Java doesn’t lag, the ability of the Java Virtual Machine (JVM) follows the principle – “code should run on any device and under any operating system”, therefore proving to be an independent programming tool.

2021 Google trends data clearly shows – Java is in race with other languages, whereas .NET is lagging and is at the last position in the trend.

The stack overflow results on programming languages, clearly show 38.4% of users working on the Java framework whereas 35.9% users using dot NET.

Java vs .NET – What is it Actually About?

Both the platforms are enterprise-level and work fantastically with high-load systems and various big data applications and complex architectures and provide a scalable and resourceful option for large-scale products.

Java, known for its exceptional multi-purpose language, is the flagbearer of ‘Write once, and you’re done’, and the .NET framework also works on desktop and server.

Java vs .NET: Dissimilarity

One’s an Object Oriented Programing language and the later a framework with C# as the programing language. However, both functions on the concept of object-oriented concept and are used in developing enterprise-driven solutions.

Microsoft .NET JAVA
Runtime Capabilities CLR JVM
Supported IDE Mono Develop, Microsoft Visual Studio Eclipse, Oracle JDeveloper and Oracle NetBeans
GUI frameworks WPF, WinForms, UWP Swing GUI JAVA, AWT, SWT
Unit Testing Microsoft Unit testing JUnit
Data Access ADO.NET, oLedDB JDBC
HTTPS Engine IIS Application Servers from Multiple Vendors, Glassfish
Remoting SOAP, OpenAPI, DCOM RMI, Rest API, GraphQL

Above all both Java and .NET focus on app development by standardized components, services and a better system app modular.

Java vs .NET: Advantages

JAVA: The benefit of using Java development platform is its sense of portability. You can easily choose the operating system and also shift as per your requirement and domain objects. Java calls the database-less due to the better Object-relation support.
The applications developed in the JAVA platform are more compatible with other platforms using more advanced integration tools like Jenkins and Travis CI.

Key features:

  • Object-Oriented
  • Multi-threaded
  • Platform-independent


  • High Performance
  • Native Threads
  • Greater SDK-JDK

Meanwhile, prominent companies like Netflix, Uber, Spotify, Cash App, and Twitter have opted for Java platform for their app development.

.NET: You get Microsoft unified environment as a benefit for using ASP .NET development. Dot NET platform works seamlessly in horizontal scalability by consequently making most of the IDEs and tools in Microsoft Developer Network accessible to the developer.

Subsequently, Microsoft ASP.NET development can be the ideal place to use various languages, editors, games, build libraries for the web, desktop, and IoT.

Key features:

  • CLR (Common Language Runtime Engine)
  • Base Class Library
  • Uncomplicated Development
  • Language Independence


  • Great Community
  • Highly Productive
  • Great 3rd party libraries
  • Stable Code

Accenture, Starbucks, Stack Overflow, Microsoft, and other major companies work on .NET platform.

Java vs .NET: Disadvantages

Is Java faster than .NET, this question is often used in the comparison but what it does not looks at are:

Cons of Using JAVA: Migration between the platforms is easy, which is the key feature of Java, but possible security breaches are the main issue when it comes to platform-agnostic solutions. Some of the Scala functions do not work with Groovy, which requires advanced software development skills.

Java’s ability to work on many platforms makes it slow sometimes. Likewise, many developers have pointed towards this issue of multi-platform nature drawback.

  • Single-paradigm language
  • Slower than natively compiled languages
  • Memory consuming
  • No unsigned types
  • Less machine interactive

Cons of using .NET: The advantage of seamless horizontal scalability seems to fade off when the support is only available for the Entity framework, resulting in a limited number of object-relational support. NET. Code managed in this framework runs slow compared to the native code, and developers depend on Microsoft for enhancements.

  • Limited Object-relational Support
  • Stability issues for new releases
  • Migrating applications is expensive
  • Vendor lock-in

Which is Better Java or .NET in the Future?

Nonetheless, both the platforms have the same purpose and have the same exact aim to help the developers and people working in different businesses and enterprises. But when it comes to IDEs and portability, consequently Java vs .NET become different. Hence the software development on both platforms has a different roadmap.

Conclusion: Which is the Best Programming Language for the Future?

Java vs .NET: The facts depict both platforms having a different approach to software development regarding IDE and portability. Both the platforms pursue the same goals and target the same segment of the market.

An excellent software can be built on .NET or Java, but also consider .NET developers are hard to find, but that does not put Java on the unskilled list. Java development needs consultants to build a complex application.

When the app in development handles more extensive user data and a more sophisticated network of user data handling, it is advised to opt for Java from the list.

The development should consider.NET when the application requires more GUI (Graphic User Interface), it is advantageous in web delivery bases system.

Misleads of the enterprise-level apps need .NET is deceptive. Enterprise-level apps are created in PHP and only then require ASP.NET and Java in line.

The significant choice arises when the project costs are considered. If you opt for Windows-based products and rely on Microsoft, you should opt for .NET to minimize expenditures; otherwise, if you select Java, it reduces certain costs. You can choose from various tools and good related software to get the right mix of Java tools.

To sum up, finding an ideal choice for java developer can be tricky. To clarify the selection among Java vs .NET is not simple, they are in the same vein. The choice should be based on infrastructure, requirements of development platforms, interoperability, and end-user environments. In short, Java and.NET provide similar tools and functionality to help in the development process.
