为接口提供所有的空实现，让使用者仅仅覆盖需要的部分；
本思想肯定有问题，慢慢考究
frame.addWindowListener(new WindowAdapter() { @Override public void windowClosing(WindowEvent e) { // TODO Auto-generated method stub super.windowClosing(e); } });
Window是一个接口，拥有众多方法等等待实现，如关闭，打开，最小化。。。。
WindowAdapter()是一个适配器，提供了所有Window方法的空实现，在不覆盖时，什么也不做
public abstract class WindowAdapter implements WindowListener, WindowStateListener, WindowFocusListener { public void windowOpened(WindowEvent e) {} public void windowClosing(WindowEvent e) {} public void windowClosed(WindowEvent e) {} public void windowIconified(WindowEvent e) {} public void windowDeiconified(WindowEvent e) {} public void windowActivated(WindowEvent e) {} public void windowDeactivated(WindowEvent e) {} public void windowStateChanged(WindowEvent e) {} public void windowGainedFocus(WindowEvent e) {} public void windowLostFocus(WindowEvent e) {} }
