import java.lang.*;

public class uhr extends java.applet.Applet implements Runnable

{
    
    GregorianCalendar cal = new GregorianCalendar();
    
    private Thread t = new Thread(this);
    
    public int sec=cal.get(Calendar.SECOND);
    public int min=cal.get(Calendar.MINUTE);
    public int hou=cal.get(Calendar.HOUR_OF_DAY);
    public int x1=220;
    public int y1=220;
    public int x2;
    public int y2;
    public int xsec;
    public int ysec;
    public int xmin;
    public int ymin;
    public int xhou;
    public int yhou;
    public double alpha=0;
    public double pi=Math.PI;
    
    public void start()
    
    {
        
        t.start();
        
    }
    
    public void run()
    
    {
        
        for (;;)
        
        {
            
            try
            
            {
                
                t.sleep(1000);
                sec=cal.get(Calendar.SECOND);
                min=cal.get(Calendar.MINUTE);
                hou=cal.get(Calendar.HOUR_OF_DAY);
                alpha=0;
                xsec=(int) (160*Math.sin(pi*sec/30)+x1);
                ysec=(int) (-160*Math.cos(pi*sec/30)+y1);
                xmin=(int) (120*Math.sin(pi*min/30)+x1);
                ymin=(int) (-120*Math.cos(pi*min/30)+y1);
                xhou=(int) (100*Math.sin(pi*hou/6)+x1);
                yhou=(int) (-100*Math.cos(pi*hou/6)+y1);
                repaint();
                
            }
            
            catch (Exception e) {};
            
        }
    }
    
    public void paint(Graphics g)
    
    {
        
        Color rot=new Color(255,0,0);
        Color weiss=new Color(255,255,255);
        
        g.drawString(hou + ":" + min + ":" + sec, 20, 20);
        g.setColor(rot);
        g.fillOval(20,20,400,400);
        g.setColor(weiss);
        g.fillOval(30,30,380,380);
        g.setColor(rot);
        
        
        while (alpha<=2*pi)
        
        {
            
            x2=(int) (198*Math.sin(alpha)+x1);
            y2=(int) (198*Math.cos(alpha)+y1);
            g.drawLine(x1,y1,x2,y2);
            alpha=(alpha+pi/6);
            
        }
        
        g.setColor(weiss);
        g.fillOval(40,40,360,360);
        
        g.setColor(rot);
        g.drawLine(x1,y1,xsec,ysec);
        g.drawLine(x1,y1,xmin,ymin);
        g.drawLine(x1,y1,xhou,yhou);
        
    }
}
