Images looping

Question

Ok I am having major problems running this program.
I need the user to enter in the command line argument;
java ImageDiplay dog jpg 3meaning that the program will select dog1.jpg, dog2.jpg
and dog3.jpg put them in the images array and loop these pictures by showing each one at a time.
My problem is how do I assign each argument to the constructor to build the images name put them in the array. and then use the array to show the pics in an applet.
import java.awt.Toolkit;
import java.awt.Image;
import javax.swing.JFrame;
import java.awt.Graphics;
* This class loads a set of images and flips through them
public class ImageDisplay extends JFrame implements Runnable
     protected Image[] images;
     protected int current_image = 0;
      * Read the basename and num_images parameters.
      * Then read in the images, using the specified base name.
      * For example, if basename is images/anim, read images/anim0,
      * images/anim1, images/anim2, etc.
     public ImageDisplay(String baseName, String fileType, int numPics)
          super("ImageDisplay");
          //add code here to load the pictures
          //create a JFrame
          //get basename
          //get numPics
          //add number to each imagename
          Toolkit tKit = super.getToolkit();
           = tKit.createImage(baseName);
          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          this.setSize(300,300);
          this.setVisible(true);
      * This is the body of the thread, the method that does the animation.
     public void run()
           Thread workThread = null;
            for (int i=0;i<images.length;++i)
                 //     tracker.waitForID(i);
                      lastLoaded = i;
                      repaint();
            while (workThread != null)
                 repaint();
                 try
                     Thread.sleep(100);
                 catch (InterruptedException e)
     }//end of method
      * This method paints the current image to the screen.
      * This method is complete.
      * @param g the graphics object that actually does the drawing
     public void paint(Graphics g)
          System.out.println("Painting");
          g.clearRect(0, 0, 300, 300);
          g.drawImage(images[current_image], 30, 30, this);
      * The main method parses the command line arguments.  Then
      * it creates a new ImageDisplay object and passes it,
      * as a target, to a thread.
     public static void main (String[] args)
          if (args.length == 3)
               ImageDisplay myDisplay = new ImageDisplay(args[0],args[1], Integer.parseInt(args[2]) );
          Runnable runner = new ImageDisplay(args[0],args[1],Integer.parseInt(args[2]) );
          Thread t1 = new Thread(runner);
          t1.start();
}
