This repo contains some examples of Design Patterns in Java; it was split off from my main https://github.com/IanDarwin/javasrc[javasrc repo] to keep the latter from becoming bottom-heavy.

== Readings

The original book that popularized Design Patterns - after they were in use for a decade in the CS community - is https://www.amazon.com/dp/0201633612[Design Patterns: Elements of Reusable Software], by Gamma, Helm, Johnson and Vlissides, known more concisely as the Gang of Four or even the GoF.

A less academic, more memorable, more fun read is O'Reilly's https://www.amazon.ca/dp/0596007124[Head-First Design Patterns].

== My Writings

The OO chapter of my https://www.amazon.ca/dp/144933704X[Java Cookbook], 3rd edition.
