parametros no processing

void setup() {
size(100, 100);

// Read the value "51" from the following text embedded in an HTML page:
// <applet code="param_example" archive="param_example.jar" width=100 height=100>
// <param name="back" VALUE="51">
// </applet>
String bgcolorStr = param("back");
int bgcolor = int(bgcolorStr);
background(bgcolor);
}

parametros de html para applet

Here is the code for the Java Program :
import java.applet.*;
import java.awt.*;

public class appletParameter extends Applet {
private String strDefault = "Hello! Java Applet.";
public void paint(Graphics g) {
String strParameter = this.getParameter("Message");
if (strParameter == null)
strParameter = strDefault;
g.drawString(strParameter, 50, 25);
}
}

Here is the code for the html program :
<HTML>
<HEAD>
<TITLE>Passing Parameter in Java Applet</TITLE>
</HEAD>
<BODY>
This is the applet:<P>
<APPLET code="appletParameter.class" width="800" height="100">
<PARAM name="message" value="Welcome in Passing parameter in java applet example.">
</APPLET>
</BODY>
</HTML>

There is the advantage that if need to change the output then you will have to change only the value of the param tag in html file not in java code.
