voidcentreOnScreen(Window win)
Centre the given window on the screen. 
Dimension screenRes = Toolkit.getDefaultToolkit().getScreenSize();
Dimension windowSize = win.getSize();
int x = Math.max(0, (screenRes.width - windowSize.width) / 2);
int y = Math.max(0, (screenRes.height - windowSize.height) / 2);
win.setLocation(x, y);
PointgetCenter(Component owner, Dimension size)
get Center 
Dimension d = owner.getSize();
Point result = new Point((d.width / 2 - size.width / 2) + owner.getLocation().x,
        (d.height / 2 - size.height / 2) + owner.getLocation().y);
return result;
PointgetCenterCoordinates(Dimension d)
get Center Coordinates 
Dimension s = Toolkit.getDefaultToolkit().getScreenSize();
Point ul = new Point();
ul.x = (s.width - d.width) / 2;
ul.y = (s.height - d.height) / 2;
return (ul);
int[]getCenteredLocation(Component comp)
get Centered Location 
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
int top = (screenSize.height - comp.getHeight()) / 2;
int left = (screenSize.width - comp.getWidth()) / 2;
return new int[] { left, top };
PointgetCenteredLocation(Window w)
get Centered Location 
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
int x = d.width - (d.width / 2 + w.getWidth() / 2);
