Java (programming language) 

 

About & History :                                                                    

Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture. Java is, as of 2014, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into 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 developed by Sun from 1991 and first released in 1995. 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).

Compilers :                                                                                                                

Start off by making sure that you downloaded the Java JDK. This contains the Javac compiler which is a command line compiler. It is available here: http://java.sun.com/javase/downloads/wid... 

After that is installed, you can download and install an IDE called Netbeans which will allow you to edit your code in a more productive environment. You can get it here: http://netbeans.org/downloads/index.html 

Netbeans will only be able to compile your Java code if the JDK is installed. Be sure to install the JDK first.
