Java Tutorial #1: Event Paradigm/Observer Pattern (Part 3/3)

In this tutorial we go through how one can implement the Event Paradigm to solve a common problem in Object Oriented design: that of independent components interacting with each other. We cover event listeners, event classes, event sources (registering listeners and firing events) and listener adapters.
