Java

A programming language expressly designed for use in the distributed 
environment of the 

Internet

 and enforces a completely object-oriented view 

of programming. Java can be used to create complete 

application programs

 

that may run on a single computer or be distributed among servers and 
clients in a network. It can also be used to build small application modules, 
or 

applets

, for use as part of a Web page. 

Kilobyte
