Java is a language—developed by Sun Microsystems, Inc.—that allows Java programmers to write small programs called Applets that you can download and use on your web page. Applets can add special effects to your web page, aid navigation, alter images or just spruce up some text. When a visitor loads your web page with a Java applet on it, the visitor’s browser downloads the applet from your web site’s server and then runs it on the visitor’s own computer.

Applet .class files contain the programming instructions they need. Some applets will use only one .class file; others will use several. You must upload all of the associated .class files into your web page directory.

There are three steps usually needed to add an applet to your web page:

1. Add the applet HTML coding onto your web page
2. Edit any Param Values as outlined by the applet’s author
3. Upload all of the associated files (.class files, images, sounds and .html) to your web server directory

To embed an Applet on your web page, use the <APPLET> Tag. Change the applet’s parameters by editing the VALUE= settings in the <PARAM> Tag(s).

Here is an example applet and its coding:

Your Browser does NOT support Java. This is a Java Slide Show Applet.

<applet code="Slidetext.class" align="baseline"
width="500" height="46">
<param name="bgcolor" value="000000">
<param name="font" value="TimesRoman">
<param name="size" value="28">
<param name="sleep" value="4000">
<param name="speed" value="6">
<param name="style" value="1">
<param name="text"
    value="...Java is different from Javascript!...">
<param name="txtcolor" value="ffffff">
Your Browser does NOT support Java.
This is a Java Slide Show Applet.
</applet>

NOTE:

• Some browsers do NOT support Java applets; hence, the warning is inserted before </applet> tag.
• If your .class file resides someplace other than the current directory (which includes your applet-contained HTML file), you must use a codebase attribute within <applet> tag to specify where your .class file resides.
