e552. getting an applet parameter.txt

这里面包含了一百多个JAVA源文件

An applet can be configured through the use of applet parameters. For example, the contents for a news ticker applet could be specified through an applet parameter. 
Here's how an applet parameter would be specified in an HTML file. The example specifies two applet parameters called p1 and p2: 

    <applet code=AppletClassName width=100 height=100>
        <param name=p1 value="some text">
        <param name=p2 value="some more text">
    </applet>

Here's how the value of an applet parameter can be retrieved: 
    String parameterName = "p1";
    String value = applet.getParameter(parameterName);
    
    parameterName = "p2";
    value = applet.getParameter(parameterName);
