import java.awt.*;

public class MyClock extends JFrame

protected MyJPanel jp;
protected JLabel a1;
protected JLabel a2;

public MyClock()

super("xMac");
// getting the Time
Calendar now= Calendar.getInstance();
int hour1=now.get(Calendar.HOUR_OF_DAY);
int min=now.get(Calendar.MINUTE);
int sec=now.get(Calendar.SECOND);

//initialize the compo.
a1=new JLabel("Time is:");

jp= new MyJPanel();

//setting the frame up
setContentPane(jp);
setVisible(true);
setSize(150,60);
