J#

J# or J sharp is a Microsoft supported language for .NET and is used by Java-language programmers to build applications and services to run on the .NET Framework. J# is Microsoft’s implementation of the Java programming language and is specially designed to allow Java-language developers to easily transition to the .NET Framework and for creating .NET applications. J# applications are not a perfect match with the Java Virtual Machine (JVM) or the Java 2 platform though J# applications can be written using Visual Studio. However, it is quite compatible with visual J++ and implements its extension to Java

NET and then compiled using third party java tools. Visual J# aims the common language runtime (CLR) and also used to develop .NET Framework applications, with XML Web services and web applications with the full use of the .NET Framework. J# is a complete implementation of the Java Language specification; it allows the majority of existing Java applications to run after recompilation or after binary conversion. But J# code is different from Java code and it is code is complied into a byte code as is Java code. This is the reason that J# cannot be compiled using a JDK or any other development environment for Java.

Microsoft developed J# to encourage Java developers to migrate to the .NET platform. The minimum eligibility required for J# is only the fundamental knowledge of Java Programming.
