调试可以通过，但运行不显示时间，帮忙看看吧
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
import java.applet.*;

public class mytest extends JApplet implements Runnable
{
  String s;
  Date d;
  JTextField jt=new JTextField();
public void init()
{
  Thread t=new Thread();
  this.getContentPane().add(jt);
  t.start();
}
public void run()
{
  while(true)
  {
    try
    {
      jt.setText(d.toString());
      Thread.sleep(1000);
      //repaint();
      }catch(Exception e){e.printStackTrace();}
    }
  }
}
