Adding Java Applets to the Page
Java applets are self-contained programs written in the Java programming language, that can be placed inline on a web page just like a graphic. There are lots of Java applets available on the Web for free from Java library sites such as the JavaBoutique ((http://javaboutique.internet.com).
Most Java applet instructions require that you add the applet to the
page using the handy <applet>
tag (made just
for the job!). However, the HTML 4.0 Spec recommends that applets be
added using the <object>
tag instead,
although this is problematic in that some browsers don’t
recognize the <object>
tag when used with
Java. In this section, we will focus on the
<applet>
method.
The <applet>
tag is a container for any
number of parameter (<param>
) tags. The
following is an example of how an <applet>
tag for a game might look:
<APPLET CODEBASE=class CODE="Wacky.class" WIDTH=300 HEIGHT=400> <PARAM NAME="Delay" VALUE="250"> <PARAM NAME="Time" VALUE="120"> <PARAM NAME="PlaySounds" VALUE="YES"> </APPLET>
The opening applet tag contains a number of standard attributes:
-
code
Tells the browser which applet will be used. Applets end with the suffix
.class
or.jar
. This attribute is required.-
codebase
This tells the browser in which directory to find the applets. If the applets are in the same directory as the page, the
codebase
attribute is not necessary.-
width
andheight
These specify the pixel dimensions of the “window” the applet will occupy. These attributes are required ...
