JFrame에 새 WindowListener 추가

Question

mainFrame.addWindowListener(new WindowListener() { 

     @Override 
     public void windowClosing(WindowEvent e) { 
      if (JOptionPane.showConfirmDialog(mainFrame, "Are you sure you want to quit?", "Confirm exit.", JOptionPane.OK_OPTION, 0, new ImageIcon("")) != 0) { 
       return; 
      } 
      System.exit(-1); 
     } 

     @Override 
     public void windowOpened(WindowEvent e) {} 

     @Override 
     public void windowClosed(WindowEvent e) {} 

     @Override 
     public void windowIconified(WindowEvent e) {} 

     @Override 
     public void windowDeiconified(WindowEvent e) {} 

     @Override 
     public void windowActivated(WindowEvent e) {} 

     @Override 
     public void windowDeactivated(WindowEvent e) {} 

    }); 

내 코드가 있습니다. 내 경우에는 쓸모없는 메서드를 모두 제거하기 위해 windowClosing 메서드 만 사용하므로 가능합니까? 적은 공간이 필요합니까?

예

mainFrame.addWindowListener(new WindowListener() { 

     @Override 
     public void windowClosing(WindowEvent e) { 
      if (JOptionPane.showConfirmDialog(mainFrame, "Are you sure you want to quit?", "Confirm exit.", JOptionPane.OK_OPTION, 0, new ImageIcon("")) != 0) { 
       return; 
      } 
      System.exit(-1); 
     } 

    }); 

은 가능합니까?
