What Is .NET?

• .NET is a free, open-source development framework that can be used to create a wide range of applications. .NET Core is a cross-platform framework that works on Windows, Linux, and macOS.
• In the late 1990s, Microsoft began creating the .NET Framework. The first beta versions of .NET 1.0 were released in early 2000.
• .NET allows you to build web, mobile, desktop, gaming, and IoT apps using various languages, editors, and libraries.
• .NET applications can be written in C#, F#, or Visual Basic. It will run natively on any compatible operating system, whether you're writing code in C#, F#, or Visual Basic.

What Is Java?

• Java is a programming language as well as a computer platform. There are numerous applications and websites that will not function unless Java is installed.
• Sun Microsystems released Java in 1995, and Oracle Corporation eventually purchased it. Billions of devices worldwide, including notebook computers, mobile devices, game consoles, medical devices, and many others, use the Java software platform.
• Java is an object-oriented programming language that is widely used. Java's principles and grammar are based on the C and C++ programming languages.
• Java is a quick, secure, and dependable programming language. Java may be found everywhere, from laptops to datacenters, game consoles to scientific supercomputers, cell phones to the internet.
• The Java Platform is a collection of technologies that enable programmers to efficiently create and run Java programming applications. It contains an execution engine, a compiler, and a collection of libraries. It is a collection of software and specs.

Fundamentals

• .NET is a free, cross-platform, open-source framework for developing a wide range of applications. Microsoft began creating the .NET Framework in the late 1990s, and the first beta versions of.NET 1.0 were released in early 2000.
• Java is a programming language and computing platform developed by Sun Microsystems that was initially released in 1995. Java is a popular object-oriented programming language and software platform utilized on billions of devices, such as notebook computers, mobile devices, gaming consoles, medical equipment, and many others.

Languages

• With .NET, you can utilize multiple languages. .NET applications can be written in C#, F#, or Visual Basic.
• Java is a programming language by itself. However, JVM (Java virtual machine) does support other languages such as Python, R, Rexx, and Ruby.

Operating System

• .NET operates only on Windows operating systems, Windows 98 or later, and Windows NT 4.0.
• Java can run on a variety of operating systems, including Microsoft Windows, Solaris, Linux, and Mac OS.

IDEs

• In .NET IDE’s like Atom, Brackets, Sublime Text, Emacs, and Vim is used. But the most common one is Visual Studio.
• Java utilizes IDEs such as Eclipse, BlueJ, IntelliJ IDEA, jGRASP, JCreator, NetBeans, Greenfoot, and JDevelop.

Libraries

• The .NET Framework Class Library is a collection of classes, namespaces, interfaces, and value types used in.NET applications.
• Class libraries in .NET have the shared library concept. They allow you to break down useful functionality into modules that multiple apps can utilize.

Some of the.NET libraries are as follows:

• Swashbuckle
• Polly
• AutoMapper
• SaasKit
• The Java Class Library (JCL) is a collection of dynamically loadable libraries that Java Virtual Machine (JVM) languages can use during execution.
• A Java library is simply a collection of classes that someone else has already created.

Some of the libraries used in Java are as follows:

• Apache Commons
• Google Guava
• Jackson

Performance

.NET makes use of natively compiled languages such as C# and C++. They are faster and use less memory than Java. .NET also allows for code optimization and writing less code, which improves performance. Shorter code also means less time spent on code maintenance and simpler debugging.

The performance of Java is due in part to its Just-In-Time (JIT) compiler and concurrency features. The Java runtime environment includes the JIT compiler.

The Java Virtual Machine immediately executes the compiled code (JVM). Because the code is not interpreted, compiling does not take any processing time or memory. As a result, a Java application runs at the same speed as a native application.

Licensing

• .NET is a free developer platform with no licensing fees and free development tools for Linux, macOS, and Windows. The .NET platform's programming languages, compilers, libraries, and runtimes are all free. There are no licensing fees for commercial use.
• Whereas in Java, since the April 2019 java 8 upgrade, all versions and updates for Java 8,9,10,11,14 are free for personal use and development. Any other use necessitates the purchase of a Commercial License.

Jobs and Salaries
