public voiddraw(java.awt.Graphics2D g, java.awt.Component c)
Draw the example

	BufferedImage image =                   // Create an off-screen image
	    new BufferedImage(65, 35, BufferedImage.TYPE_INT_RGB);
	Graphics2D ig = image.createGraphics(); // Get its Graphics for drawing

	// Set the background to a gradient fill.  The varying color of
	// the background helps to demonstrate the anti-aliasing effect
	ig.setPaint(new GradientPaint(0,0,Color.black,65,35,Color.white));
	ig.fillRect(0, 0, 65, 35);

	// Set drawing attributes for the foreground.
	// Most importantly, turn on anti-aliasing.
	ig.setStroke(new BasicStroke(2.0f));                   // 2-pixel lines
	ig.setFont(new Font("Serif", Font.BOLD, 18));          // 18-point font
	ig.setRenderingHint(RenderingHints.KEY_ANTIALIASING,   // Anti-alias!
			    RenderingHints.VALUE_ANTIALIAS_ON);

	// Now draw pure blue text and a pure red oval
	ig.setColor(Color.blue);
	ig.drawString("Java", 9, 22);
	ig.setColor(Color.red);
	ig.drawOval(1, 1, 62, 32);
	
	// Finally, scale the image by a factor of 10 and display it
	// in the window.  This will allow us to see the anti-aliased pixels
	g.drawImage(image, AffineTransform.getScaleInstance(10, 10), c);

	// Draw the image one more time at its original size, for comparison
	g.drawImage(image, 0, 0, c);
