Java是否具有对C＃类似的事件的本机支持？ [英] Does Java have native support for events, similar to that of C#?

问题描述

但是我知道它有GUI事件。

我错过了什么吗？ java有一个事件处理机制吗？

我知道我可以实现发布者订阅者模式，但是我正在寻找Java中的本地支持。 >

我似乎记得一些关于Java的事情在Java 5或6中添加事件，但我不记得在哪里听到这个，我可能会做的。

基本上，我将一个设备包装在一个java类中，设备会抛出事件，我正在寻找最合乎逻辑的方法。我主要来自.Net背景，我正在寻找类似.Net（C＃）中的事件。

任何帮助将不胜感激。

解决方案

正如你已经说过的那样，您可以与publisher-subscriber / Observer模式完全一样。只需要更多的脚步。

不，Java没有对事件的本机支持，像C＃与代理人一样。

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 handling mechanism?

I'm aware that I can implement a publisher subscriber pattern, but I'm looking for native support within Java.

I seem to remember something about Java Adding events in either Java 5 or 6 but I can't remember where I heard this and I may be making it up.

Basically I'm wrapping a device in a java class the device throws events, and I'm looking for the most logical way of exposing this. I come mostly from a .Net Background and I'm looking for something like the events in .Net (C#)

Any help would be appreciated.

解决方案

As you already stated, you can do the exact same thing with the publisher-subscriber/Observer pattern. It just requires a bit more legwork.

And no, Java does not have native support for events, like C# does with delegates.
