I'm able retrieve and set the coordinate's of the rectangle passed as parameters from an html file but i'm unable to set the colour passed as parameter from an html file,how to do this? I have tried this code,but its not working properly.

import java.awt.*;
import java.applet.*;
/* <applet code="ParaRect" width=1200 height=1000>
<param name=x value=100>
<param name=y value=200>
<param name=color value="red">
</applet> */
public class ParaRect extends Applet{
    public void paint(Graphics g){ 
       String x=getParameter("color");
       g.setColor(Color.x);
       g.fillRect(Integer.parseInt(getParameter("x")),Integer.parseInt(getParameter("y")),150,100);
    }
}

Does this answer your question? [Converting a String to Color in Java](https://stackoverflow.com/questions/2854043/converting-a-string-to-color-in-java) — Federico klez Culloca, Oct 06 '20 at 06:22
Use hexadecimal string color values ("#FFFFFF" is white). To convert hex to a Color use: `Color c = Color.decode("#FFFFFF");` Also google `HTML color`. — DevilsHnd - 退職した, Oct 06 '20 at 06:35
