Teach yourself JAVA in 21days
The World Wide Web, for much of its existence, has been a method for distributing passive
information to a widely distributed number of people. The Web has, indeed, been exceptionally
good for that purpose. With the addition of forms and image maps, Web pages began to become
interactive—but the interaction was often simply a new way to get at the same information. The
limitations of Web distribution were all too apparent once designers began to try to stretch the
boundaries of what the Web can do. Even other innovations, such as Netscape’s server push to
create dynamic animations, were merely clever tricks layered on top of a framework that wasn’t
built to support much other than static documents with images and text.
Enter Java, and the capability for Web pages of containing Java applets. Applets are small
programs that create animations, multimedia presentations, real-time (video) games, multi-user
networked games, and real interactivity—in fact, most anything a small program can do, Java
applets can. Downloaded over the net and executed inside a Web page by a browser that supports
Java, applets are an enormous step beyond standard Web design.
