| Why Java? |
Java was developed as a response to problems programming
in C++. It is intended to be a "simple, object oriented, distributed,
interpreted, robust, secure, architecture neutral, portable, high performance, multithreaded, dynamic" programming language. |

Although Java can be used to write stand-alone applications,
the concept of "applets," or little programs, which could be
included with HTML documents and distributed over the Internet caught on,
and led to the development of Java-capable browsers.
Check BrowserWatch
to see if you and your visitor's browser can support java. |
| How Java Works
|
A Java-capable browser, once
it sees one of these APP tags, will download the code for the program described
therein, and attempt to compile and run it on the client's machine.
There are considerable security issues inherent in having potentially
thousands of these applets downloaded and executed on a distributed basis
across the Internet. Malicious or mischevious use could be devastating
for companies and individuals' computers, but Sun says there is very little
to worry about. They have built a multi-layer model of security into the
language, compiler, and the browsers.
At SFSU we have the Java Developer Kit (JDK) installed on hosts Libra
and WWW.
