窗體沒(méi)有加入監(jiān)聽(tīng)器？public class Demo10 { public static void main(String[] args) { JFrame f = new JFrame(); f.addWindowListener(new WindowAdapter(){ @Override public void windowClosing(WindowEvent e) { // TODO Auto-generated method stub System.out.println("hello"); System.exit(1); } }); f.setVisible(true); f.setLocationRelativeTo(null); }} |
