是否有效實例化windowListener接口？

WindowListener是一個接口？但是，如何實例化是有效的，如下所示？我們不能實例化接口嗎？是否有效實例化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 

     } 
    };

請參閱[*如何編寫窗口監聽器*]（http://docs.oracle.com/javase/tutorial/uiswing/events/windowlistener.html） – trashgod

這是創建一個實現WindowListener接口的新匿名類。

感謝您的回覆。然後，對於以下內容，擴展WindowAdapter的新匿名類？ WindowListener l = new WindowAdapter（）{ \t \t \t public void windowClosing（WindowEvent e）{ }我是否正確？ – Rose
