5. Focus points of Difference Between Java and .NET

5.1 .NET vs JAVA: Operating System

Operating systems have been a good point to focus on when it comes to making informed business decisions for the apps. Undoubtedly, Java had the upper hand in this area, since it could run on any operating system with the help of compilers and Java Runtime Environment, whereas .NET was completely controlled by Microsoft and only operated on Windows. 

If we compare the current strategy by Microsoft, then it has changed a lot since .NET core was introduced to the market. The strategy is now at a very different level. Initially, their fundamental value is to ensure software developer independence and make them focused on a single platform. As a result, now they have made .NET Core an open-source platform with no licensing fees. .NET works and is compatible with other operating systems like Windows, Linux, and iOS is quite easy. However, it is still mainly targeting Windows users.

5.2 .NET vs JAVA: Integrated Development Environment

Integrated development environments aka IDEs make the job of a developer simpler. It helps to code, test software applications, and maintain documentation. For Java, if we talk about IDEs, there are many but the four most popular and used IDEs are Oracle NetBeans, Eclipse, IntelliJ Idea, and Oracle Jdeveloper. The latter was created expressly for simpler authoring and testing. Java’s IDEs can also be customized and made into built-in plugins.

On the other hand, if we talk about .NET, Microsoft Visual Studio is the default IDE. Visual studio encompasses a large set of IDEs which helps to build all types of apps using its functionalities.

5.3 .NET vs JAVA: Performance & Compatibility

Java is a developer-centric platform, until the code is performed, there is no requirement for code conversion. Java can get it converted using Machine learning. And then, on the other side. .Net is put together and then executed on the system. C# performs better in a runtime context because of this. Speaking of the older Java versions, prior to Java 7, there was no support for simple and simplified data structure or switch cases.

When it comes to compatibility, both .NET and Java have equal competency and they are compatible across major operating systems and devices.

5.4 .NET vs JAVA: Language Support

One of Java’s distinctive advantages is that it uses a single language across several platforms. Nonetheless, the applications created with it run independently across multiple operating systems. We know for a fact that the J2EE framework makes Java their default language but when it comes to .NET, it is compatible with all other languages such as C#, F#, and VB.NET.

The .NET platform, on the other hand, supports C#, F#, and Visual Basic giving .NET developers flexibility while working on enterprise solutions.

As a result, it might be claimed that .NET offers a multiprogramming environment, but Java is built on a single programming language, which is useful in supporting many programming languages.

5.5 .NET vs JAVA: Tools

Although, for a fact we know that Java has many methods for scaling up the performance, it is still not as quick as .NET. When it comes to .NET, they make use of natively compiled languages such as C# and C++. Using .NET tools from Microsoft Developer Network a .NET software developer can deliver rapid results with minimal utilization of memory than Java. .NET also allows for code optimization and with lesser codes, you can improve the performance and efficiency. Shorter code also implies less time spent on code maintenance and debugging. Such functionalities are unquestionably appealing to both developers and clients. We have discussed IDEs in detail in the previous section because when it comes to tools, they are also considered important and can be integrated with other third-party apps and other apps too. So, in this section of which tools perform the best among both- JAVA vs .NET performance battle, .NET is unquestionably the victor.

5.6 .NET vs JAVA: Language & Security

One of Java’s most important features is that it employs a single language across all platforms. Nonetheless, the applications developed with it run on a wide range of operating systems. Java may handle other languages, including Python, Ruby, Groovy, Scala, and Kotlin.

On the other hand, the .NET  framework, on the other hand, may support languages such as C# and C++, which are great for backend development and web services. Over 20 languages are now supported. You may programme in whatever language you choose, including VB.NET, C#.NET, Perl, and many more, with this. It is useful when you need to produce code that is only available on the Windows platform.

5.7 .NET vs JAVA: Popularity

This part is quite questionable because when it comes to popularity, there is cut-throat competition between the two. When it comes to speed, Java programming language is developed from C and C++, therefore, there are many parallels between Java and .NET. However, because Java is platform-independent, its code may run everywhere.

On other hand, .NET provides a general-purpose and easy programming language that includes various reusable components, type checking, array limits, garbage collection, and uninitialized variable checks. This increases durability, robustness, and efficiency. So, apart from these differences, the performance of .NET and Java is quite comparable and popular.

5.8 .NET vs Java – Speed of Coding

Software developers who prefer using Java programming language, use a variety of threads which helps them to simplify the process of management and procession of instruction in the sequence. However, when it comes to speed, the .Net framework is an absolute leader in this field. Also, it provides many components that can be reused as it is an object-oriented platform so when you compare the time consumed to build similar apps in both languages, it will be less time-consuming and this is the main reason why developers choose Java.

On the other side, .Net is an object-oriented technology that allows you to reuse various components that are developed on the same app. So if we compare Java and .Net, .Net is surely less time-consuming than Java. So it will be fair to say that the winner in terms of speed of coding is .Net.

5.9 .Net vs JAVA – Scalability

If you are planning to build large-scale applications, then Java and .Net both are equally effective. One can use Java or .Net to create enterprise-level applications as both of them are stable and fully rolled out when it comes to scalability.

The selection of technology, in this case, depends on the personal preferences of the project as both these technologies are a perfect fit for building complex and large-scale applications for businesses.

5.10 .Net vs Java – Learning Curve

Both technologies are easy to learn but if we compare them Java offers more educational and documentation material to study which is viewed by a larger user community available on the market so it can be a little overwhelming.

On the other hand, the .Net framework is comparatively easy but at the same time, its educational and documentation material provided by Microsoft continues to attract new support.

5.11 .Net vs Java – Market Share

In 2018, a survey was conducted by Indeed.com to analyze the job postings on its website and to check which programming languages were highly used by development companies. In that survey, they discovered that Java was the most demanding skill in the market that covered more than 35% of the job posts.

Whereas if we talk about .Net, it was quite below that list. So according to that survey, Java developers are in huge demand as compared to .Net developers. However, that’s not all. If we go through the overall industry and check the results, you’ll find numerous websites written in .Net.
