public class GraphicsUtil
extends Object
A class that extends the drawXxx and fillXxx methods of java.awt.Graphics. In particular, it adds line width (pen thickness) arguments to most of the drawXxx methods, a Color argument to most of the drawXxx and fillXxx methods, and a Font argument to drawString and drawChars. Also creates drawCircle and fillCircle methods.

Rather than including the Graphics object in a call to a constructor, the methods are all static, and the Graphics is included as the first argument to each of the methods. Don't forget to include it.

For instance, here is how you would draw a 10-pixel wide blue line from (10,10) to (200, 200) and a 5-pixel thick red circle of radius 50 centered at (200, 200): 

   public void paint(Graphics g) {
     ...
     GraphicsUtil.drawLine(g, 10, 10, 200, 200,
                           10, Color.blue);
     GraphicsUtil.drawCircle(g, 200, 200, 50,
                             5, Color.red);
     ...
   }
