Event-Driven Architecture Pattern: An Example

The previous lessons covered the principles of Event-Driven Architecture (EDA). A worked example makes those principles concrete. In this section, we'll explore a simple EDA using Java, covering the creation of event producers, event consumers, the event bus, and event channels.

Creating an Event

We start with an Event. In Java, we can represent an event as a simple class. This class would typically hold information relevant to the event. For our example, let's create a basic VehicleEvent for a traffic management system.

public class VehicleEvent {
