How to join 2 thread classes in one applet

Question

I am having problems with 2 classes, each class has an applet which has a thread, but I want to run both classes in one applet so that at the end have an animation of the race. I need to start both threads in one class.

TortuleThread

public class TortuleThread extends Applet implements Runnable {
    public int y= 0;
    Thread thread;
     public void init(){
            thread = new Thread(this);
            thread.start();
            resize(800,700);
        }

     public void paint(Graphics g){
            g.setColor(Color.green);
            g.fillOval(80, 30+y, 50, 50);
            g.fillOval(88, 70+y, 30, 30);
            g.fillOval(70, 50+y, 20, 20);
            g.fillOval(120, 50+y, 20, 20);
            g.fillOval(85, 25+y, 20, 20);
            g.fillOval(105, 25+y, 20, 20);

            g.setColor(Color.BLACK);
            g.fillOval(92, 80+y, 6, 6);
            g.fillOval(105, 80+y, 6, 6);

            y=y+15;
        }
    public void run()
    {
    int i=0;
    System.out.println("start tortule");

    while(i<5)
    {
        repaint();
        try{
            Thread.sleep(5000);
            System.out.println("Tortule");
        }catch(InterruptedException ex)
        {   
        }
        i++;
    }
    System.out.println("end tortule");
}
}

HareThread

public class HareThread extends Applet implements Runnable {
    public int y = 0;
    Thread thread;

    public void init() {
        thread = new Thread(this);
        thread.start();
        resize(800, 700);
    }

    public void paint(Graphics g) {
        g.setColor(Color.gray);
        g.fillOval(58, 3 + y, 8, 30);
        g.fillOval(68, 3 + y, 8, 30);
        g.fillRect(55, 30 + y, 20, 20);
        g.fillRect(40, 50 + y, 30, 30);
        g.setColor(Color.white);
        g.fillOval(60, 32 + y, 6, 6);
        g.fillOval(68, 32 + y, 6, 6);
        g.setColor(Color.red);
        g.fillOval(64, 40 + y, 6, 6);
        g.setColor(Color.gray);
        g.fillOval(30, 60 + y, 15, 15);

        y=y+15;
    }

    public void run() {
        int i = 0;
        System.out.println("start hare");
        while (i < 5) {
            repaint();
            try {
                Thread.sleep(2000);
                System.out.println("hare");
            } catch (InterruptedException ex) {
            }
            i++;
        }
        System.out.println("end the hare");
    }
}

GraphicRace

public class GraphicRace extends Applet{

    public static void main (String [] args)
    {
    TortuleThread tortule = new TortuleThread();
    Thread hare = new Thread(new HareThread());
    tortule.start();
    hare.start();
    }
}
