是否有效实例化windowListener接口？

WindowListener是一个接口？但是，如何实例化是有效的，如下所示？我们不能实例化接口吗？是否有效实例化windowListener接口？

WindowListener l1=new WindowListener() { 

     public void windowOpened(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 

     public void windowIconified(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 

     public void windowDeiconified(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 

     public void windowDeactivated(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 

     public void windowClosing(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 

     public void windowClosed(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 

     public void windowActivated(WindowEvent e) { 
      // TODO Auto-generated method stub 

     } 
    };

请参阅[*如何编写窗口监听器*]（http://docs.oracle.com/javase/tutorial/uiswing/events/windowlistener.html） – trashgod

这是创建一个实现WindowListener接口的新匿名类。

感谢您的回复。然后，对于以下内容，扩展WindowAdapter的新匿名类？ WindowListener l = new WindowAdapter（）{ \t \t \t public void windowClosing（WindowEvent e）{ }我是否正确？ – Rose
