What are some examples of the pub-sub pattern in Java?

The pub-sub pattern in Java can be implemented using various libraries. One common example is using Java's built-in Observer interface.

Can you explain how the Observer interface works?

Sure! The Observer interface allows a subject to notify multiple observers about state changes. Observers register themselves to receive updates.

Are there any libraries that simplify this pattern?

Yes, libraries like Google Guava and Apache Kafka provide robust implementations of the pub-sub pattern, making it easier to manage.

Can you provide a code example using Google Guava?

Certainly! Here's a simple example using Guava's EventBus to implement pub-sub.
