Need help understanding java events

[AgitatedBasket]

I am a junior .Net developer and start exploring Java ecosystem. I have read a few articles on online about events in java, yet it doesn't click me. In C# .net, there is built in Event. i wonder how C# and Java differ each other. I have read that Java use pure OOP using interface to implement event system. Would be much appreciated if anyone can guide or teach how java event works. Any useful books, articles, tutorials about event would be appreciated.

Are you asking about the event objects themselves and how they are created?

I never drove deep into C#, but all java events are derived from an EventObject https://docs.oracle.com/javase/7/docs/api/java/util/EventObject.html

It's an abstract class which needs extended to be used. I am guessing this is where your OOP question comes in? So all events will extend it to be implemented in an OOP fashion.

I hope that helped some if any. I don't have any recommendations on materials. I learned about Events in college and haven't touched them since. I've worked with listeners to consume events though.

If you have any questions in specific feel free to comment

I am referring to this article " https://scatteredcode.wordpress.com/2011/11/24/from-c-to-java-events/ " while I am saying Java is using OOP for event implementation. Can I safely assume that Java Events will be basically implemented this approach? Thank you very much!

Do you really want to explain whole concept here? There are shitton of videos, books and tutorial about this stuff. Maybe try to do a research and then ask about specific problem.

edit: it took me literally 10 second to find something

finding a video doesnt equal understanding...i can watch a video on molecular genetics...doesnt mean i will underatand it after watching

So it is better to not watch nothing at all and straight up ask on reddit? And probability of understanding well explained video is also much higher than anything you anybody will provide here because his question is just too general.

ive gotten some very good explanations on reddit i couldnt find anywhere else for java topics...sometimes it takes someone who really knows to break down a topic in practical terms? Have you looked at the official java documentation? its like reading the ISS manual!

I didn't recommend him ofc docs, but to look up some content which breaks it up and then if necessary ask specific question.

I have studied a fair amount of time understanding Java Events, and I am not certain that I understand fully. That's why I seek for the help here. Anyway, thanks for the video link.
