Difference between Java vs .NET. Who wins?

Updated: Jun 16, 2023

What is Java?

Java vs .NET (1)

Java is a programming language that is cross-platform, general-purpose, class-based, and object-oriented. Even though Java was introduced 26 years ago, it is still as popular as ever: it ranked 5th in the rating of the most popular languages, according to a Stack Overflow Developer Survey.

Java works in quite an interesting way. You write a code, it is compiled to bytecode then, and Java Virtual Machine converts it, according to the requirements of different devices. Consequently, a developer needs only one code for different platforms.

Advantages of Java:

  • Simple programming language

  • Object-Oriented Programming

  • Platform-Independent

  • Distributed computing

  • Secure language

  • Multi-threaded

  • Cheap and economical to maintain

Disadvantages of Java:

  • Single-Paradigm Language

  • Memory consuming and slower than natively compiled languages

  • Slow and has a poor performance

  • No Unsigned Types

  • Does not provide so attractive look and feels of the GUI

  • Less machine interactive

What is .NET?

Java vs .NET (2)

.NET is an open-source framework developed by Microsoft and is oriented to users of Microsoft products. When it was first introduced in 2002, the framework was used for Microsoft only. It means that you could not code or run developed applications on Linux, Android, or iOS. It was a close-source system as well.

In 2016, Microsoft introduced .NET Core which changed the position of the framework on the market. If many companies did not consider .NET because of its limited usage before, they started to include it in the discussions about the framework choice. It has become a good opponent for Java.

Advantages of .NET :

  • Multi-tiered software architecture

  • Cross-platform design

  • Object-Oriented Programming

  • Great Caching System

  • Universal .NET Standard

  • Flexible Deployment and Easy Maintenance

  • Automatic monitoring in ASP.NET

Disadvantages of .NET:

  • Limited Object-Relational Support

  • Memory Leaks

  • Slower than Native Code

  • Vendor lock-in

  • Migrating applications is expensive

  • Stability Issues for New Releases

The Difference: Java vs .NET





Java is an object-oriented and platform-independent high-level programming language.

.NET is a cross-platform, open-source software framework used for developing a software applications.


Java requires JVM (Java Virtual Machine) for execution means during runtime.

.NET requires CLR (Common Language Runtime) for execution means during runtime.

Support system

It supports multiple Operating Systems a third-party system.

It only supports Windows Operating System.


In Java JDBC (Java Data Base Connectivity) is used for the database connection.

In .NET ADO (ActiveX Data Objects (ADO) is used for database connection.


In Java, Coding is well-optimized, but the final code is long

In .NET, it has reusable components that speed up the coding process.

Programming Languages

Java, Kotlin, Clojure, Groovy, Scala, PHP, Ruby, Python, JavaScript and more.

C#, VB.NET, C++, .NET, PHP, Ruby, Python and more!

Supported IDE

Eclipse, IntelliJ Idea, Oracle, NetBeans, and Oracle HDeveloper

Microsoft Visual Studio, Rider, MonoDevelop.

Web Service Support



Who Wins?

When it comes to Java Vs .NET, there is no right or wrong choice. Both of these technologies have their positive and negative aspects. Either of the two can help you create feature-rich and dynamic enterprise apps. Choosing between Java vs. dot net depends upon the requirements of your website, available development resources, and the end-users.

To grow and excel in a competitive market, you will need both languages. You, as a business, can take advantage of the positive aspects of each resulting in high-performing websites and applications.

And to take advantage of both languages, you must get in touch with an expert web development company in India. Only an expert can help you develop an expert solution providing you with the best services you are looking for. Cheers!
