编译完成，这样用把下面的村程*.htm文件保存到.class目录
<TD height=200 width=200><FONT size=3><APPLET align=middle 
            code=jhanabi.class height=200 width=200><PARAM NAME="para_bits" VALUE="10000"><PARAM NAME="para_max" VALUE="150"><PARAM NAME="para_blendx" VALUE="50"><PARAM NAME="para_blendy" VALUE="50"><PARAM NAME="para_sound" VALUE="2"><PARAM NAME="width" VALUE="650"><PARAM NAME="align" VALUE="baseline"><PARAM NAME="code" VALUE="jhanabi.class"><PARAM NAME="codeBase" VALUE="./"><PARAM NAME="height" VALUE="270">
</APPLET>
</FONT>
</TD>那两个声音文件，可以从我的那个里面llrock.myrice.com/applet/fireworks.rar找到，该一下名字。
你可以在llrock.myrice.com/applet/fireworks.html看到我的效果。
也可以下载llrock.myrice.com/applet/fireworks.rar到本机运行，
我自己还没有满意，所以不公开代码先，这只是测试版本。
