<param name ="name1" value="green"/>
and then in the java code i need 2 set this parametre as a color ex:
g.setColor(Color.?);
?= the color in the parametre name
how can i do this ?

Answer 1

The following snippet of code assumes that the permissible values
for the applet parameter "name1" are hexadecimal RGB values.
"0xFF0000" would be red.
"0x00FF00" would be green.
"0x0000FF" would be blue.
String s;
Color c;
// get the applet paramter from the html file
s = getParameter("name1");
try
    int aR, aG, aB; // RGB-Values
    aR = Integer.valueOf(s.substring(2,4),16).intValue();
    aG = Integer.valueOf(s.substring(4,6),16).intValue();
    aB = Integer.valueOf(s.substring(6,8),16).intValue();
    c = new Color(aR, aG, aB);
catch( Exception e )
    c = new Color(0x00, 0xFF, 0x00);
g.setColor(c);
