.NET vs Java: Difference and Comparison

.NET and Java are both technologies that are used for programming in the Information Technology industry.NET is a framework and Java is a programming language respectively.

Both are used in the development and creation of business websites, apps. Choosing the right technology for a specific project can be difficult, so in this article, we will discuss the key differences between .NET and Java.

Key Takeaways

  1. .NET is a software framework developed by Microsoft, while Java is a programming language and platform created by Sun Microsystems (now owned by Oracle).
  2. .NET primarily supports languages like C# and VB.NET, while Java uses the Java programming language for application development.
  3. Both platforms offer extensive libraries, tools, and community support, but .NET is more closely tied to the Windows ecosystem, whereas Java is known for its cross-platform compatibility.

.NET vs Java

Java is a platform and object-oriented high-level programming language developed by Sun Microsystems. NET is an open-source and cross-platform framework developed by Microsoft. It is used for software application development. Java supports multiple operating systems, unlike NET, which supports one.

NET vs Java

.NET is a type of framework which is created and developed by Microsoft. The Integrated Development Environment (IDE) for .NET is Microsoft Visual Studio Code.

The languages which are used by .NET developers are C#, C++, F#, and VB.NET. For doing work on enterprise solutions, .NET provides good flexibility. 

Java is a type of programming language which is object-oriented and is derived from C++. If we talk about IDE then primary it has four IDEs and that are Oracle NetBeans, IntelliJ Idea, Oracle JDeveloper, and Eclipse.

Languages used by Java developers are JavaScript, Groovy, Scala, and Clojure.

Comparison Table

Parameters of Comparison.NETJava
PlatformIt can only be used in the operating system which is provided by Microsoft.It can be used in any operating system.
AdvantageIt contains many IDEs and tools which are developed by Microsoft.It is platform-independent which makes it more flexible.
DisadvantageIt is very costly as compared to other frameworks.Java is less secured as compared to. NET.
PerformanceIt is more efficient, durable, and robust than Java.It is derived from C++ and also most developers prefer Java for development.
Market ShareIt has a low market share as .NET developers are less.30 percent of the development sector is occupied by Java developers.

What is .NET?

.NET is a programming technology that is a type of framework and is created and developed by Microsoft and runs only on the operating system of Microsoft.

It contains a library of classes of frameworks of Microsoft. It has a special feature that provides the use of the same written code in multiple languages.

.NET was released on 14 February 2001 and the latest version was released on 1 May 2021. The operating system in which it can be used is Windows 98 or windows released after that.

The platforms which can be used for .NET are IA-32, x86-64, and ARM. The website of .NET is dotnet.microsoft.com. .NET framework is used for the majority of applications created by the Windows platform.

Visual Studio is the IDE. NET. FCL in .NET can provide data access, user interface, database connectivity, cryptography, and also web development.

The production of software in windows is done by the combination of source code programming with the .NET framework.

The architecture of the .NET framework contains Common Language Infrastructure which is used by the framework to support multiple languages, Common Language Runtime which provides services like garbage collection, memory management and exceptional handling, Assemblies, Class Library and C++/CLI. C, C++, and F# are some languages used in .NET development.

What is Java?

Java is a computer language that is used for programming and development in many software areas such as software development, app development, web development, etc.

It is an object-oriented programming language I.e., a language that contains classes, objects and can perform operations like encapsulation, data abstraction, polymorphism, and also inheritance.

The Java code which is compiled can run on all Java-supported platforms. For running a program in Java, a virtual platform named Java Virtual Machine is needed.

The syntax of Java language is derived from C and C++ but it has more complex syntax than these two languages. Java is one of the most popular programming languages which is in use by developers.

Java is used by approx. 30 percent developers in the IT industry.

Java was designed by James Gosling in 1995 and is currently developed by Oracle Corporation. The Filename extensions of Java include .java, .class, .jar, .jmod.

The website of Java is oracle.com/java. Most of the programming languages used today that are influenced by Java are Ada 2005.

Java does not need any special platform as it is platform-independent which means it can be programmed in any operating system with Java Virtual Machine.


Main Differences Between .NET and Java

  1. .NET is a framework that can only be performed in a limited operating system like windows while Java can be performed in any operating system.
  2. .NET is currently very less in demand and also there are very fewer developers using .NET while Java is the most demanded language in the IT sector.
  3. Most of the web-based websites are developed by .NET while most of the backend development in apps is done by Java.
  4. .NET is a framework that offers you a lot of flexibility and makes development easy while Java Developers are easier to find and Java is also used in open-source solutions.
  5. .NET is the best development programming technology if we only talk about apps that are based on windows while Java can be used in the development of any operating system-based apps.
