* paint method in your own class that extends Canvas
* @param g where to paint e.g. printer, screen, ram
public void paint (Graphics g)
// display word "today" centred at x,y
FontMetrics fm = getFontMetrics( g.getFont( ) );
String wording = "today" ;
int xadj = fm.stringWidth( wording )/ 2;
// position bottom left corner of the text
g.drawString(wording , x-xadj, y );
// draw a red line from x1,y1 to x2,y2
g.setColor( Color .red );
g.drawLine( x1 , y1, x2, y2);
// draw an pre-existing Image. imX,imY is top left corner of the Image.
g.drawImage ( image , imX, imY , imWidth, imHeight , this);
} //end paint
