Is there a Java equivalent to Actionscript's 3.0 Event dispatching? Or, how do I effectively communicate between unrelated class instances?

I'm starting out in Android development and this has been bugging me a little.

If class A creates an instance of class B and class C, what is the easiest way to communicate between B and C?

In Actionscript 3, I could dispatch an event and have a listener pi开发者_JS百科ck it up and act on it but I cannot see something like that in Java. Of course there is the option of passing a reference of B and C into the other from class A but when the path isn't this simple it becomes very hard to follow.

What is the best way to accomplish this in Java/Android?

For Android, I think the best way is to use the Intent api: http://developer.android.com/guide/topics/intents/intents-filters.html
