<P>The examples on this page provide demonstration applets for
the purpose of demonstrating and evaluating Java Plug-in. Hence, the HTML
of each page explicitly specifies the use of the Java<SUP><FONT SIZE=-2>TM</FONT></SUP>Plug-in
rather than the default Java virtual machine contained in your browser.&nbsp;
<P>Java Plug-in is installed as part of the public Java<SUP><FONT SIZE=-2>TM</FONT></SUP> SE Runtime Environment.
Once installed, the Java Plug-in loads automatically
and transparently to render Java applets.&nbsp;
<P>All of these applets leverage Java<SUP><FONT SIZE=-2>TM</FONT></SUP> SE Development Kit MKTG_VERSION features, and are thus dependent
on features in that version.&nbsp; For information on compatibility, see <A HREF="http://java.sun.com/javase/MKTG_VERSION/compatibility.html">Compatibility
with Previous Releases</A>.&nbsp;&nbsp; The applets include those in the <TT>demo</TT>
directory of the Java SE Development Kit, plus a few extras.&nbsp; Each applet is viewed
by opening the respective web page (see the links below) in your
Web browser.&nbsp;

<TITLE>A Clock (1.6)</TITLE>

<h1>A Clock (1.6)</h1>
<hr>
<applet code="Clock.class" width=170 height=150>
alt="Your browser understands the &lt;APPLET&gt; tag but isn't running the applet, for some reason."
Your browser is completely ignoring the &lt;APPLET&gt; tag!
</applet>
<p>
The clock applet now has three parameters; the background
color (bgcolor), the main foreground color (the hands and
dial) (fgcolor1) and the secondary foreground color (the
seconds hand and numbers) (fgcolor2). These three parameters
are hexadecimal RGB numbers (like the ones used for the body
bgcolor tag in HTML). For example:
<p>
&lt;applet code="Clock.class" width=170 height=150&gt;<br>
&lt;param name=bgcolor value="000000"&gt;<br>
&lt;param name=fgcolor1 value="ff0000"&gt;<br>
&lt;param name=fgcolor2 value="ff00ff"&gt;<br>
&lt;/applet&gt;<p>
would give you a black background, a red dial and hands, and purple numbers.
<p>
For those who don't convert to hexadecimal easily, here are some common
values:
<ul>
<li>black = 000000
<li>blue = 0000ff
<li>cyan = 00ffff
<li>darkGray = 404040
<li>gray = 808080
<li>green = 00ff00
<li>lightGray = c0c0c0
<li>magenta = ff00ff
<li>orange = ffc800
<li>pink = ffafaf
<li>red = ff0000
<li>white = ffffff
<li>yellow = ffff00
