Wow, stumbled upon this video while i was searching how Event Listeners work in JavaFX. I love how your video is easy to digest, but informative enough to kickstart my confused mind to learning the topic more in depth. +sub! I'll be following your updates from now on

Thank you so much, I have been wrongly trying to use an event or action listener. This is what I have been looking for.

Q: why is it that you can instantiate the ChangeListener if it’s an interface? It would make sense to me if there is a concrete class that can instantiate it but your example uses a class with the same ChangeListener name.
