What is JAVA?
Java is the name given to a language developed by Sun Microsystems. It was designed to have the following benefits:
Java applets run in a special, "closed" environment on the user’s browser. This means that applet does not allow access to the system’s hard disk or other resources. As a result, it is not possible to deliver malware (e.g. viruses) to a computer using Java. That is, products using Java are secure.
- Runs anywhere
Java code is pcode. This gives it two special properties: it relatively small in size (reducing the download time) and it can run on any machine. This means that applets written in Java can run on
a Unix machine, Windows machine or Mac with little alteration unlike any other applications.
- Low development cost
It is simlar to other object orientated programming languages such as C++. This reduces the learning time for application developers.
The professional interface in GMS Webmail uses Java applets to provide a very rich interface to users. The mail client interface uses applets to display the folders, the tree down the left hand side, calendar views, etc. This gives the user a vastly better experience than using simple HTML.
