title: JApplet setBackground not working
body: <p>I am wondering why the method setBackground() is not actually making the background black. I have feeling this has something to do with the class implementing JApplet as opposed to Applet but I can not figure out the specifics. It's really bugging me. Any help is appreciated!</p>
  
  <pre><code>import javax.swing.*;
  import java.awt.*;
  
  public class Rocket extends JApplet
  {
      private final int APPLET_WIDTH = 200;
      private final int APPLET_HEIGHT = 200;
  
      private int[] xRocket = {100, 120, 120, 130, 130, 70, 70, 80, 80};
      private int[] yRocket = {15, 40, 115, 125, 150, 150, 125, 115, 40};
  
      private int[] xWindow = {95, 105, 110, 90};
      private int[] yWindow = {45, 45, 70, 70};
  
      private int[] xFlame = {70, 70, 75, 80, 90, 100, 110, 115, 120, 130, 130};
      private int[] yFlame = {155, 170, 165, 190, 170, 175, 160, 185, 160, 175, 155};
  
      public void init ()
      {
          setBackground (Color.black);
          setSize (APPLET_WIDTH, APPLET_HEIGHT);
      }
  
      public void paint (Graphics page)
      {
          page.setColor (Color.cyan);
          page.fillPolygon (xRocket, yRocket, xRocket.length);
  
          page.setColor (Color.gray);
          page.fillPolygon (xWindow, yWindow, xWindow.length);
  
          page.setColor (Color.red);
          page.drawPolyline (xFlame, yFlame, xFlame.length);
      }
  }
