WindowListener中可以实现窗口关闭功能的方法是()。
A．public void windowOpened(WindowEvent e)
B．public void windowClosed(WindowEvent e)
C．public void windowClosing(WindowEvent e)
D．public void windowDeactivated(WindowEvent e)请帮忙给出正确答案和分析，谢谢！
参考答案
正确答案：B
解析：本题考查事件监听器的概念。窗口事件接口WindowListener有几个关键方法，应该注意，如publicvoidwindowClosmg(WindowEvente)是把退出窗口的语句写在本方法中；publicvoidwindowOpened(WindowEvente)是窗口打开时调用；publicvoidwindowClosed(WindowEvente)是窗口关闭时调用，选项B正确：publicvoidwindowIconified(WindowEvente)是窗口图标化时调用；publicvoidwindowDeiconified(WindowEvente)是窗口非图标化时调用；publicvoidwindowActivated(WindowEvente)是窗口激活时调用；publicvoidwindowDeactivated(WindowEvente)是窗口非激活时调用。
