When I was studying in the university (more than 10 years ago), I learn how to build and embed Java Applets on web pages using Java 1.0 (after that Java 1.2), the functionality is quite limited since there’s no default 3D support in Java yet. Compared to Flash (then Flash 3.0 during that time), Java Applet is more suitable for math and scientific application, generating graphs and kaleidoscope base on mathematical formula, and everything.
Heck, Netscape Navigator still rules the day during that time. But what about now? With the technology explosion, does anyone here still use Java Applets?
