Quick Summary:

.NET vs Java are two popular programming languages for creating server-side, online, and desktop applications. 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.

When it comes to developing software, .Net & Java are two of the most popular technologies. Both are used to build enterprise-level applications. First released in 2002, .net is a Microsoft framework whereas, Java is being around since mid-1990 and it is an open-source language. While both technologies have their unique features & capabilities. They are often compared and evaluated based on various factors such as scalability, performance, ease of use, community, and platform compatibilities.

Because both .NET and Java can be used to achieve the same development goals, there is often a misunderstanding about which technology is which. 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 developers to construct online apps.

But before diving into the key distinction between Java and .NET, let’s look at the overview of both technologies.

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 34.55 percent of the vote.

Popular Programming Language

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++.

Key comparisons between .Net vs Java

As with any technology, there are going to be some differences when compared to others and .net and java are no different. Following are a few of the critical differences between .net and java. For better understanding, we have divided these differences into technical and non-technical comparisons.

Technical Comparison

Following is a few of the technical comparison that you should keep in mind while you are deciding which one to choose between java vs .net. Let’s kick start this comparison by comparing the performance of both technologies.

.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.

.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.

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.

.NET Vs JAVA: Learning Curve

Both .NET vs JAVA are easy to learn. But if compared, it can be a little overwhelming to learn Java given the length of the documentation, whereas learning .NET is comparatively simple.

.NET vs JAVA: Syntax

Following are the syntax of .NET and JAVA

using system;
     class Program
           static void Main(string[] args)

Java Syntax

public class class_name 
     public static void main(String[ ] args) 

.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.

.NET vs JAVA: Example

The following are the examples for .NET vs JAVA.

             Console.WriteLine("Hello, world!");


/* 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");

.NET vs. JAVA: Licensing

.NET is a free, open-source platform with no licensing fees and free development tools for Linux, Windows, and macOS. There is no cost for compilers, libraries, and programming languages as open-source programming languages. There are no licensing fees for commercial use.
