Both platforms allow large-scale applications to be built using high-level programming languages. Microsoft .NET and Java are two popular programming languages that have been picked as significant solutions by various companies. Let’s compare the two and see which one is the most excellent fit for your project.
Because we can use both java and .NET to achieve the same development goals, there is often a misunderstanding about which technology is. While both Java and .NET are frequently referred to as frameworks, only .NET is a framework in the strictest sense. The ASP.NET web application framework is used by the .NET platform to allow professional .Net developers to construct online apps.
Let’s have a look at the critical distinctions between Java and .NET.
What is .NET vs Java?
Let’s start with understanding the basics of .NET vs java
What is .NET?
.NET is a Microsoft open-source framework aimed towards Microsoft users. The framework was designed specifically for Microsoft when it was initially released in 2002. This implies you won’t code or execute produced apps on Linux, Android, or iOS. It was also a closed-source system.
In 2016, Microsoft released .NET Core, which shifted the framework’s market position. Today, .NET 5 (formerly known as .NET Core) is the most popular framework since it is free of the limitations of earlier windows-only frameworks. .NET 5 has been successfully used to construct projects of varying levels of complexity.
.NET has first launched 19 years ago and is still quite popular; according to the StackOverflow Developer survey, it is the most popular framework and library in the other frameworks and libraries division, with 72.67 percent of the vote.
This framework supports C#, C++, F#, and more programming languages. And adheres to an object-oriented approach. Padigram .NET also includes the Common Language Runtime, which allows you to run compiled source code.

Java is a fascinating language to work with. You develop a program, which is subsequently compiled to bytecode and converted by the JVM to meet the needs of various devices. There are three versions of Java:
- Java EE (Enterprise Edition)
- Java SE (Standard Edition)
- Java ME (Micro Edition)
As a result, a skilled java developer simply needs to write one code for all platforms.
Java is utilized in every industry you can think of, including eCommerce, IoT, finance, and big data, but it hasn’t yet achieved its peak in that field. CLU, Simula67, Lisp, Smalltalk, Ada, C++, C#, Eiffel, Mesa, Modula-3, Oberon, Objective-C, UCSD Pascal, Object Pascal were all influences on Java. Ada 2005, BeanShell, C#, Chapel, Clojure, ECMAScript, Fantom, Gambas, Groovy, Hack, Haxe, J#, Kotlin, PHP, Python, Scala, Seed7, Vala, JavaScript, JS++.

Difference Between Java And Dotnet: Key Differences
The critical differences between .NET vs JAVA are shown here for your convenience.
Technical Comparison
Following are the technical comparison between .NET vs JAVA
.NET vs JAVA: Operating System
One of the most significant differences between Java and .NET is that JAVA, through its compiler and JRE, can operate on any operating system, as it adheres to the “write once, execute anywhere” approach. .NET, on the other hand, is limited to Windows and its various versions. Although there are a few open-source versions of .NET, they all cater to Windows users. Java’s code can run on any platform, thanks to the JVM. Java has a significant advantage over .NET since it is platform-independent and portable.
.NET vs JAVA: Integrated Development Environment
The Java IDE comprises three parts: a code editor, a compiler, and a debugger. Eclipse, Intellij Idea, Oracle NetBeans, and, in addition, an Oracle Jdeveloper that is specifically developed for this purpose makes writing and testing code easier. These IDEs include built-in plugins and auto-fill options, which can increase java’s versatility while also providing opportunities for creativity.
The .NET platform, on the other hand, comes with Visual Studio, which aids in the editing, building, and running customization of API behavior through the use of library macros. Apart from that, developers do not need to test IDEs and other tools ahead of time.
Java vs Dotnet: Support for Languages
One of the essential aspects of Java is that it uses a single language for all platforms. Nonetheless, the software may run on a variety of operating systems. Python, Ruby, Groovy, Scala, and Kotlin are all supported by Java.
The .NET framework, on the other hand, can support backend languages like C# and C++. It currently supports over 20 languages. This allows you to program in any programming language of your choice, including VB.NET, C#,.NET, Perl, and many others. It is, nevertheless, quite handy for producing specific code for the Windows platform only.
As a result, it is possible to conclude that. However, .NET provides a multi-programming environment but supports a single platform, whereas java is based on a single programming language that supports various environments.
.NET Vs JAVA: Performance
When it comes to performance, java’s syntax is developed from c and c++. Therefore the two languages have a lot in common. On the other hand, Java is platform-agnostic, meaning that its code can be run on any platform.
.NET, on the other hand, provides a general-purpose and straightforward programming language that includes type checking, array bounds, garbage collection, and uninitialized variable checks. This increases the endurance, robustness, and efficiency of your system. Only the features of unchecked and checked expectations are arrayed in Java.
Dotnet vs java: Speed of Coding
Although Java has different threads to make handling and processing sequences of instructions easier, .NET remain the leader in terms of coding speed. Because .NET is an object-oriented technology with reusable components, producing the same software in .NET takes less time than designing the same app in Java.
.NET Vs JAVA: Scalability
After the application is fully deployed, both technologies are among the most stable. As a result, both JAVA and .NET are frequently employed for the creation of complex enterprise-level applications.

}
}
}
Java Syntax
public class class_name
{
public static void main(String[ ] args)
{
System.out.println("Content_you-want_to_display");
}
}
.NET vs JAVA: Security
In terms of comparing security, both technologies are secure. They support code signing and enforce an execution sandbox. Java is platform-agnostic, so the chances of security breaches are pretty high can be the reason for significant concern. Whereas, .NET provides more security than compared to java.

}
}
}
Java
/* This is a simple Java program.
FileName : "HelloWorld.java". */
public class HelloWorld
{
//Your program begins by calling the main().
//Prints "Hello, World" to the terminal window.
public static void main(String args[])
{
System.out.println("Hello World");
}
}
