Listening and handling Java Events without UIs

Question

I'm working on a Java project which requires we be on the lookout for changing events in the system. However, many of these events are on the back-end and can constantly change, and such they aren't looking for any button input. Every example of event handlers and listeners I've researched seems to involve a GUI, however; is it possible to do this without a GUI component to attach handlers and listeners to?

Yes, for example the observer pattern is very often used for this (but listeners can be used, too). — Philipp Wendler, Mar 04 '15 at 18:22

You can try java.beans.PropertyChangeSupport which lets you register java.beans.PropertyChangeListeners. A change will be indicated via a call to firePropertyChange.
