Java支持多少种侦听器？

How many kinds of listeners supported in Java? I am a newbie and just know there is the ActionListener, which listens the button clicked. I want to a JLabel in a JFrame to update with time. So, is there any listeners for time to update the label in a frame?

Java支持多少种侦听器?我是一个新手,只知道有一个ActionListener,它监听点击的按钮。我希望JFrame中的JLabel能够随时更新。那么,是否有任何听众有时间更新框架中的标签?

As mentioned by MadProgrammer, an ActionListener used inside a Swing based Timer should do the job.

正如MadProgrammer所提到的,在基于Swing的Timer中使用的ActionListener应该可以胜任。
