import javax.swing.*;
import java.awt.*;
class One extends JFrame
{
  JLabel jj;
  JPanel pp;
  public One()
  {
    jj=new JLabel();
    pp=new JPanel();
    pp.add(jj);
    Container cc=getContentPane();
    cc.add(pp);
  }
  void display(ImageIcon n)
  {
    for(int i=0;i<i+1;i++)
    {
      try
      {
        jj.setIcon Thumbs down

;
        Thread.sleep(1000);
      }
      catch(InterruptedException e)
      {}
    }
  }
  public static void main(String args[])
  {
    One rr=new One();
    rr.setSize(400,300);
    rr.show();
  }
}
class Two implements Runnable
{
  ImageIcon nnn;
  Thread t;
  One one;
  public Two(ImageIcon n)
  {
    nnn=n;
    one=new One();
    t=new Thread(this);
    t.start();
  }
  public void run()
  {
    synchronized(one)
    {
      one.display(nnn);
    }
  }
  public static void main(String args[])
  {
    ImageIcon aa=new ImageIcon("a.gif");
    ImageIcon bb=new ImageIcon("b.gif");
    ImageIcon cc=new ImageIcon("c.gif");
    Two t1=new Two(aa);
    Two t2=new Two(bb);
    Two t3=new Two(cc);
  }
}

为什么没有循环显示?
