- If you have done any web surfing, you've
probably already seen Java Applets. Applets are programs that run
inside of a web page using the resources the web browser has to
offer such as a Java Virtual Machine (JVM) and the default set of
class libraries.
- When you initially hit a web page with an
incorporated Java applet, you usually see a gray box where the
applet will show up and then slowly, the applet loads and appears
in the space of the gray box.
- If you are looking for an example, Gamelan
(http://www.gamelan.com) has hundreds.
- In addition to appearing in a web page,
applets can appear in their own windows. That is, they can appear
within their own application frame which will popup from the web
browser's window. This frame can be moved and iconified separately
from the web browser's window.
- However, applets that appear in their own
window typically display a message like, "Warning: Applet Window" in
the bottom of their frame. This tells the user that the frame is
part of a Java applet running from inside the browser. The web
browser designers added this feature to prevent an applet from
masquerading as some other window, such as a system password entry
window or as some other application.
- The AWT class java.awt.Applet defines an
applet. This class provides all of the basic features and methods
which makeup an applet object.
