AWT Event Listeners
事件侦听器表示负责处理事件的接口。Java 为我们提供了各种事件侦听器类，但我们将讨论那些最常使用的类。每个事件侦听器方法都有一个参数，该参数作为 EventObject 类的子类的对象。例如，鼠标事件侦听器方法将接受 MouseEvent 的实例，而 MouseEvent 派生自 EventObject。
The Event listener represent the interfaces responsible to handle events. Java provides us various Event listener classes but we will discuss those which are more frequently used. Every method of an event listener method has a single argument as an object which is subclass of EventObject class. For example, mouse event listener methods will accept instance of MouseEvent, where MouseEvent derives from EventObject.

这是一个标记接口，每个侦听器接口都必须对其进行扩展。此类在 java.util 包中定义。
It is a marker interface which every listener interface has to extend.This class is defined in java.util package.
