推荐答案

ActionListener文档的

ActionListener Doc's

用于接收动作事件的侦听器界面.该类 有兴趣处理一个动作事件来实现这一点 接口，并且使用该类创建的对象已注册 组件，使用组件的addActionListener 方法.当动作事件发生时，该对象的 actionPerformed方法被调用.

The listener interface for receiving action events. The class that is interested in processing an action event implements this interface, and the object created with that class is registered with a component, using the component's addActionListener method. When the action event occurs, that object's actionPerformed method is invoked.

MouseListener文档的

MouseListener Doc's

用于接收有趣"鼠标事件的侦听器界面 (按，释放，单击，进入和退出)在组件上. (追踪 鼠标移动和鼠标拖动，请使用 MouseMotionListener.)

The listener interface for receiving "interesting" mouse events (press, release, click, enter, and exit) on a component. (To track mouse moves and mouse drags, use the MouseMotionListener.)

从文档中您可以看到此接口的用法完全不同.虽然只能将MouseListener与gui元素结合使用，但在没有gui时也可以使用ActionListener，例如与计时器结合使用.

From the docs you can see that the usage of this interfaces is completly different. While you can use the MouseListener only in combination with gui elements, the ActionListener is also used when there is no gui, for example in combination with a timer.
