Is there an standard class for Events in Java?
<p>I wrote a Listener. Now I want to notify it, when a change occurs. Nothing special. </p>

<p>Now I'm asking myself: 
Is there I standard class for Events that I can use, or do I have to write a new one by myself?</p>

<p>I know there ara java.awt.Event and AWTEvent. But I am not working directly at GUI level here. Furthermore we are using Swing at GUI level. So I'm not shure if it is a good idea to mix Swing and AWT. </p>

<p>Thx</p>
