In the world of technology, there are many development frameworks available. Out of the many languages present, Java and .Net often go hand in hand in the programming world. Both Java and .Net platforms perform similar functions. While both Java vs .NET are often referred to as frameworks, only .NET is actually a framework in the strictest meaning of this word. ASP.NET is used by .NET to create different applications. Java is a programming language, while .NET is a framework that can use several languages. Let us have a look at the major difference between Java and .Net.

Key Differences Between Java vs .Net

The Key Difference between Java and .Net are explained in the below-mentioned points:

  • Java is basically a programming language, while .Net is a framework. Java can be considered as a platform with JE frameworks like J2EE. JEE, etc. It has a Java runtime environment which has JVM, just in time compiler and bytecode writer. It is a language with numerous libraries which can be used over any operating system. .Net, on the other hand, uses Windows Operating System, Windows enterprise servers. Its framework consists of Common Language Runtime,framework class libraries, and ASP.NET. It also has its own building block services and visual studio.
  • .Net has a proprietary platform of Microsoft which will be more secure than any open source platform. Security is a major concern, which is easily handled by Asp.Net developers as a closed platform. For Java, due to lack of resources security can be an issue. Common Language Runtime of .Net is better than JVM, as JVM simply converts the code into bytecode for underlying operating systems. This is not directly for computing machines and is a bit slower than CLR. Java has many IDEs for its programming like Eclipse, NetBeans, etc.Net, on the other hand, has a Visual Studio.

Java vs .Net Comparison Table

Below is the list of points describe the comparison between Java vs .Net

Basis of ComparisonJAVA.NET
Basic DifferenceJava is a programming language and can work on any operating system. Java also provides Java virtual machine (JVM) which allows code should run on any device and any operating system. It is therefore considered to be a portable language. Java supports languages like Python, Ruby, etc..Net is mainly considered to be a framework. It mainly focuses on Windows and supports various versions of Windows. .Net supports languages like C#, C++, VB.NET, etc. It supports various web services by default, as it is built in.
Integrated Development EnvironmentJava IDEs provide a code editor, debugger, compiler and elements like Maven which help in building the code with ease. There are a few IDEs like Eclipse, NetBeans, IntelliJ IDEA which make the development process easier. The platforms are user-friendly and even beginners can easily start using them. Eclipse has a lot of plugins that allow developers to write good code and also test it.Visual studio is integrated with .net. It includes many features like language-specific environments. The .net IDE acts as a single workspace which has multiple document interface which helps in development activities like editing, compiling, etc. The main feature of this IDE is that it provides form creation at design time. It hence saves time and helps speedy development. It helps in customization of appearance and behavior of application using different macros.
Performance, compatibility and other factors.Below factors provide play a major role in a performance of Java:

1) Java is an interpreted language and hence the code is not converted to machine language until executed.

2) LINQ is not available with JAVA

3) Java 7 has the facility of using a switch statement on string variable but not the older frameworks




Below factors provide play a major role in a performance of .NET:

1).Net is compiled and run on the operating system where the code is deployed.

2) LINQ enables a user to write queries directly instead of using stored procedures

3) C# enables you to use a switch statement on a string variable.

4)C# supports native generic data support

Advantages and DisadvantagesJava is a portable language and hence it can be run on any operating system. You can build your application or website easily on any platform. Java usually calls database less often as all its domain objects are already present. Many integrating connectors are available for Java and they are easily available over the internet. Also, code written in Java is backward compatible and can be easily migrated from one operating system to another.

One of the disadvantages of Java is security. Security is mostly compromised in platform agnostic solutions. Also, Scala is incompatible with Groovy and hence needs better development skills. Also though, multi-platform makes Java special, on the other hand, it tends to make Java slower.

The Microsoft provides a complete unified environment as .Net platform. It provides complete scalability which provides all tools and IDEs over the Microsoft network.

The disadvantage of .Net is that support is available only for Entity framework. It limits the object-relational support. The managed code runs slower than native code in this framework. The developers have to depend on Microsoft for all updates, features and its enhancements.

Similarities1)Java has a three-tiered architecture which enables developers to build tiered web applications.

2) It is one of the best languages for enterprise web development.

1) .Net also provides a multi-tier framework which provides facilities where business logic and data are captured.

2)It also provides the best platform as a framework and provides automatic garbage collection.

Conclusion – Java vs .Net

To conclude, both  Java vs .Net are superior languages and it depends on the developer’s skills, requirements and the infrastructure whether Java or.Net is to be used. A user must calculate project costs for both Java and .Net platforms and if they rely on Windows more, then they can go for .Net. Java is suitable for web projects but .Net works well for projects involving web services and API. Hence it is best to analyze your requirements check your preference for both Java vs .Net languages which will help you finalize a language for your use. Ultimately the overall operational efficiency of your business is what that matters.
