Java
is a
proprietary programming language that
is used to develop web applications that
work on web pages and can run over
networks. Java usually works through an
applet that is a small application or
executable file. These programs provide
user interactivity
and functionality to web sites. Java can be used to build complex systems
that involve several different computers
interacting across networks providing distributed
processing and works in conjunction with wireless
technologies. JavaScript
is a programming language used on
the web called a scripting
language that runs on the client-side
of the web architecture. It was created
by Netscape Corporation who support and distribute it over the Internet.
