Talk of software programming languages and two candidates that promptly come to our minds are .NET and Java. The duo has captured the developer’s interests and inclinations for years now. And if a choice must be made between the two, the task is harder.

Comparing .NET vs Java for the selection of the preferred programming language is no simple game. Both Java application development and .NET application development have been reigning at the top.

Organizations have been leveraging them for creating web apps and websites as they both are efficient for server-side and desktop applications. As we look at Dot Net vs Java, Java is a renowned programming language and .NET is a software framework created by Microsoft.

Through this detailed article on .NET vs Java, we attempt to go through the overview of both these languages and then foray into their pros, and cons, companies using them, and parameter-based comparison. This will help stakeholders of all genres and stature like business owners, CTOs, developers, product owners, project managers, etc. to take a final call.

What is .NET?

.NET is a free, cross-platform, open-source developer platform for building many different types of applications. With .NET, you can use multiple languages, editors, and libraries to build for web, mobile, desktop, games, IoT, and more.

Powered by the tech giant Microsoft, .NET is a well-known development framework that is platform agnostic and can be utilized across multiple platforms like Windows, Linux, and macOS.

Developers can create a variety of web, desktop, and mobile applications with various editors, development instruments, and libraries. It has been leveraged by organizations globally for projects of varied genres and domains.

The .NET framework supports different languages such as C++, C#, etc. with an object-oriented concept. It has a Common Language Runtime (CLR) that is responsible for the execution of compiled source code.

Developers can develop next-gen applications and web services with reusable components, making the application code error-free and increasing productivity.

What is Java?

Java is a programming language and computing platform first released by Sun Microsystems in 1995. It has evolved from humble beginnings to power a large share of today’s digital world, by providing a reliable platform upon which many services and applications are built.

As one of the most popular object-oriented programming languages, Java has been reigning on the top for decades now, for the versatile websites and applications that it can create. There are billions of devices, worldwide, that are using Java – be it mobile phones, gaming consoles, computers, medical instruments, etc.

Developers can execute Java applications in a fast, secure, and effective way. Java is based on C and C++.

Organizations can develop mobile apps, enterprise apps, embedded applications, games, and web-driven content, with Java. It is secure and simple with great community support.

It has been of the maximum value in modern-day technological advancements like IoT, AI, ML, eCommerce, etc. It is class-based and written as code, compiled to bytecode, after which Java Virtual Machine converts it based on device needs.
