ava can also be used to create small programs, known as “applets,” to be embedded in web pages. For instance, a web page using Java could contain an interactive weather map, a live display of subway trains, or a video game, without the need for the web server to do all of the work. Unlike normal software such as .EXE files, these “applets” can not access or delete your personal files unless they ask for and are given express permission to do so. In the real world, users hardly ever give permission for this, so applets generally don’t ask.As of this writing, Java is usually (though not always) included as standard equipment on Windows PCs. If you choose to use Java applets on your site, you can invite your users to download the Java plug-in from Sun’s website, using the “Get It Now” button on that site.
