windowadaptertest.java

这个是Java的swing相关的典型的源码

// this example demonstrate the use of adapter class for low-level event listener interface.
// and the use of anonymouse class(匿名类)

import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

import javax.swing.JFrame;

public class WindowAdapterTest {

        System.exit(0);
      }
    };
    frame.addWindowListener(listener);
    frame.setSize(300, 300);
