我在windowClosing中加了如下代码：
int option =JOptionPane.showConfirmDialog(null,"Exit now ?","Exit dialog",JOptionPane.YES_NO_CANCEL_OPTION,JOptionPane.QUESTION_MESSAGE);
switch (option) {
case JOptionPane.YES_OPTION : System.exit(0);
break;
case JOptionPane.NO_OPTION:
break;
}

但是我点no的时候它仍然会退出程序不知道为什么请指教 Blush
