Design Pattern rich code base? [closed]

Question

Am new to design patterns, could you recommend a open code base (preferably in java) that has design patterns used explicitly and elegantly. Reading up GOF has left me confused am looking for a project that used a few patterns that interacted with each other. thanks.

Answer 1

You can look at JUnit and some of its docs. Also, JUnit is extremely useful tool by itself. I think any Java developer must know how to use it.

You can also find interesting conversation with Erich Gamma, posted on Artima.com:

1. How to Use Design Patterns
2. Erich Gamma on Flexibility and Reuse
3. Design Principles from Design Patterns
4. Patterns and Practice
5. Eclipse's Culture of Shipping

Maybe, not all parts of that conversation are relevant to your question, but they all are very interesting.
