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.[10][11] 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).
Java technology allows you to work and play in a
secure computing environment. Upgrading to the
latest Java version improves the security of
your system, as older versions do not include
the latest security updates. Java allows you to play online games, chat with people around the world, calculate your mortgage interest, and view images in 3D, just to name a few. |
