class Applet
Here is the skeleton for our applet:
import java.applet.Applet ;
import java.awt.* ;
public class SnowFlakeBasic extends Applet
{
  Graphics graph;
   
  // draw a star consisting of six lines of length size
  // radiating from the point (x,y)
  //
  private void drawStar( int x, int y, int size )
  {
    .  .  .  .
  }
         
  public void paint ( Graphics gr )
  { 
    graph = gr;
    int width  = getSize().width;
    int height = getSize().height;
    .  .  .  .  .
    drawStar( . . . . );
  }
}
We extend the Applet class and override the 
paint() method.
The paint() method is called when the browser needs to fill
in the applet's part of the screen.
