## 6.3 Drawing Graphics

Example 6.2 shows a fancier version of our simple applet. As you can see from Figure 6.2 , we've made the graphical display more interesting. This applet also does all of its drawing in the `paint()` method. It demonstrates the use of `Font` and `Color` objects.

This example also introduces the `init()` method, which is used, typically in place of a constructor, to perform any one-time initialization that is necessary when the applet is first created. The `paint()` method may be invoked many times in the life of an applet, so this example uses `init()` to create the `Font` object that `paint()` uses.

#### Example 6.2: An Applet with Fancier Graphics

    import java.applet.*;
    import java.awt.*;
    public class SecondApplet extends Applet {
      static final String message = "Hello World";
      private Font font;
      // One-time initialization for the applet
      // Note: no constructor defined.
      public void init() {
        font = new Font("Helvetica", Font.BOLD, 48);
      }
      // Draw the applet whenever necessary.  Do some fancy graphics.
      public void paint(Graphics g) {
        // The pink oval
        g.setColor(Color.pink);
        g.fillOval(10, 10, 330, 100);
        // The red outline. Java doesn't support wide lines, so we
        // try to simulate a 4-pixel wide line by drawing four ovals.
        g.setColor(Color.red);
        g.drawOval(10, 10, 330, 100);
        g.drawOval(9, 9, 332, 102);
        g.drawOval(8, 8, 334, 104);
        g.drawOval(7, 7, 336, 106);
        // The text
        g.setColor(Color.black);
        g.setFont(font);
        g.drawString(message, 40, 75);
      }
    }
