JAVA
Java
is a general-purpose 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 compiled
Java code can run on all platforms that support Java without the need
for recompilation. Java applications are typically compiled to
bytecode
that can run on any Java
virtual machine (JVM) regardless of computer
architecture.
As of 2015, Java is 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 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).
