I didn't really understand the internal process of why I could detect click events just by importing EventListener.

Until now, I thought that I should import EventListener to detect any event without thinking too much about it.

However, I am looking into the internal handling of EventListener.

There are pages like the ones below, but I didn't know how to deal with them internally.

https://docs.oracle.com/javase/7/docs/api/org/w3c/dom/events/EventListener.html#handleEvent(org.w3c.dom.events.Event)

I understand that you are doing a lot of things with the handleEvent method in EventListener.
Can't I see the source code of the handleEvent?

For example, java may not necessarily be java.

Thank you for your cooperation.

EventListener#handleEvent Source Code

If you download and install the JDK and deploy C:\Program Files\Java\jdk1.8.0_77\src.zip, you can see src\org\w3c\dom\events\EventListener.java, for example,

Instead, if you want to know how these EventListener are handled within the event processing system (internal processing on the object side that generates the event), com/sun/org/apache/xerces/internal/dom/DocumentImpl.java may be helpful.

For example, java may not necessarily be java.

If you'd like to know more about common UI event processing, it might be easier to look around
