This Java applet has been created using Sun Java JDK 1.2.2.
This applet was also converted to Swing Java to improve "look and feel". Although this version could be set up for MS and Netscape browsers by Java Plug-in software, which would be practicable in an intranet environment, it cannot be used on the Internet, without necessitating users to download the necessary Java plug-in software. For this reason, the non-Swing version has been installed on this web site. The UML structure of the Swing version is depicted here, which produces the corresponding GUI shown.
