ComponentEvent:主要处理组件大小的改变，位置的改变，或是可见与不可见状态(hidden or visible)等。
ContainerListener:主要在处理组件的加入或移出容器。
FocusListener:主要在处理焦点的取得或移开焦点等操作。
MouseListener:主要就是在处理鼠标是否在某个组件上，是否按下鼠标键，是否离开某个组件等操作，主要针对鼠标按键与位置 作处理。
MouseMotionListener:主要就是在追踪鼠标的位置，如(X,Y)坐标的位置，主人是针对鼠标坐标与拖曳操作作处理。
WindowListener:主要在处理窗口的所有操作。如处理active窗口或是de-active窗口，处理窗口的最大、最小化，处理窗口的关闭 、打开、退出等。
以上所述的每种EventListener都是一种interface,里面只有定义这个EventListener的interface,然后在这个类中，把要处理事 件的程序代码写在此interface的方法中。这是处理事件的标准操作，当然还有其他编写模式，如：利用inner class的匿名类方法 ，就可以不用在class后面加上implements EventListener的表示法，或是利用Adapter类，就不用一一将interface中的每种方法都 实现。
让我们来了解一下，每一种EventListener的interface到底提供了哪几种方法要我们实现(Implement)!我们把事件区分成是由 Swing或是AWT所引发：

在java中提供两个方法让你知道到底是哪个组件触发了事件，那就是getSource()与getActionCommand();getActionCommand() 方法是ActionEvent类所提供，而getSource()方法是EventObject类所提供，但ActionEvent类继承了EventObject类，因此这两个 方法ActionEvent都可以使用，看下面的例子就知道了：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class EventDemo5 extends WindowAdapter implements ActionListener {
JButton b1 = null;
JButton b2 = null;
public EventDemo5() {
JFrame f = new JFrame("EventDemo5");
Container contentPane = f.getContentPane();
contentPane.setLayout(new GridLayout(1, 2));
b1 = new JButton("按我有声音喔");
b2 = new JButton("按我可开新窗口");
b1.addActionListener(this);
b2.addActionListener(this);
contentPane.add(b1);
contentPane.add(b2);
f.pack();
f.show();
f.addWindowListener(this);
}
public void actionPerformed(ActionEvent e) {
if (e.getSource() == b1)// getSource判断哪个按钮被按下了。
Toolkit.getDefaultToolkit().beep();
if (e.getSource() == b2) {
JFrame newF = new JFrame("新窗口");
newF.setSize(200, 200);
newF.show();
}
}
public void windowClosing(WindowEvent e) {
System.exit(0);
}
public static void main(String args[]) {
new EventDemo5();
}
}

}
public void actionPerformed(ActionEvent e) {
if ((e.getActionCommand()).equals("按我有声音喔")) // getActionCommand()方法会返回按钮上的文字字符串。
Toolkit.getDefaultToolkit().beep();
if ((e.getActionCommand()).equals("按我可开新窗口")) {
JFrame newF = new JFrame("新窗口");
newF.setSize(200, 200);
newF.show();
}
}
public void windowClosing(WindowEvent e) {

}

}
}
