what is java language?

"Java language" redirects here. For the natural language from the Indonesian island of Java, see Javanese language. This article is about a programming language. For the software package downloaded from java.com, see Java SE. Not to be confused with JavaScript.

It is intended to let application developers "write once, run anywhere" (WORA),[15] meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.[16] Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use,[17][18][19][20] particularly for client-server web applications, with a reported 9 million developers.[21] Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. The original and reference implementation Java compilers, virtual machines, and class libraries were originally released by Sun under proprietary licences. As of May 2007, in compliance with the specifications of the Java Community Process, Sun relicensed most of its Java technologies under the GNU General Public License. Others have also developed alternative implementations of these Sun technologies, such as the GNU Compiler for Java (bytecode compiler), GNU Classpath (standard libraries), and IcedTea-Web (browser plugin for applets). The latest version is Java 8 Update 121 which is the only version currently supported for free by Oracle, although earlier versions are supported both by Oracle and other companies on a commercial basis.

what is c# ?

C# is designed to be a platform-independent language in the tradition of Java (although it is implemented primarily on Windows). It's syntax is similar to C and C++ syntax, and C# is designed to be an object-oriented language. There are, for the most part, minor variations in syntax between C++ and C#. Main has no return type, there are no semicolons after class names, there are some (to C++ programmers) strange decisions regarding capitalization - such as the capitalization of Main. Other a few differences, the syntax is often the same. This decision is reasonable, in light of the fact that C syntax has been used with several other languages - notably Java. Similar to Java, C# does not support multiple inheritance; instead it provides Java's solution: interfaces. Interfaces implemented by a class specify certain functions that the class is guaranteed to implement. Interfaces avoid the messy dangers of multiple inheritance while maintaining the ability to let several classes implement the same set of methods. Another helpful feature of C# is garbage collection. Therefore, it is unnecessary to include a destructor for each class unless a class handles unmanaged resources; if so, it's necessary to release control those resources from within the class (The Finalize function is used to clear up these unmanaged resources; it can even be abbreviated with the same syntax as a C++ destructor). Of course, C# also provides direct access to memory through C++ style pointers, but these pointers are not garbage collected until specifically released by the programmer. C#, as part of the .NET framework, is compiled to Microsoft Intermediate Language (MSIL), which is a language similar to Java's bytecode. MSIL allows C# to be platform independent and runs using just in time compiling. Therefore programs running under .NET gain speed with repeated use. Furthermore, because the other languages that make up the .NET platform (including VB and Cobol) compile to MSIL, it is possible for classes to be inherited across languages. The MSIL, like bytecode, is what allows C# to be platform independent. The potential for C# is great if the .NET platform succeeds. C# is designed to take advantage of the design of .NET, and Microsoft has poured a great deal of money into .NET. Do you need to learn C#? If you know C++, you'll probably be able to pick it up quickly, and yes,

you can still use C++ with .NET. It's important to keep an eye on C# to see how it will affect you.
