        {
        Color.white,Color.black,Color.blue,Color.red,
        Color.yellow,Color.orange,Color.cyan,Color.pink,

    float f;
    Thread thread;

    public void init()
    {
        random = new Random();        Thread thread = new Thread(this);
        g = getGraphics();
        thread.start();
    }    public void run()
    {
        while(true)
        {
            //生成随机坐标
            int x = (int)(Math.random() * 100);
            int y = (int)(Math.random() * 100);
            g.setColor(colors[(int)(Math.random() * 10)]);
            //在APPLET上画点!
            g.fillOval(x,y,5,5);
            try
            {
                thread.sleep(50);
            }
            catch(Exception e)
            {
                System.out.println(e);
