Does Java have native support for events, similar to that of C#?

Question

I\'m a bit confused from what I\'ve heard Java doesn\'t do events.

But I know that it does GUI events.

Am I missing something? Does java have an event handli

Answer 1

I'm not knowledgeable about C#, but Java Beans that are not UI components can certainly notify Listeners about state changes using Events:

This has been part of the Java Beans spec since it first came out. Note the date on the tutorial: it's vintage 2000.

The source and listener have to be running in the same JVM. You'd have to use a proxy to communicate with something running in another JVM, but it could be done.

I Googled for the C# events tutorial and found this. Java's registering of listeners and firing of property changed events was reminiscent of what I saw when I skimmed the C# tutorial. Did I miss something important? (I'll admit that I didn't read deeply - no time right now.)
