You can now get a professional version of my design patterns quick reference from DZone. This newly published version has the same diagrams as my version but it is a bit more robust in that it offers a description, a “use when” section, and an implementation example for each pattern. I tried to take all the examples from real world scenarios and applications so that they would be as easy to relate to as possible.
This new version is a 7 page spread as opposed to my slimmed down 2 page version. Both are still available and, in my opinion, very useful.
There is no feasible way to incorporate code samples into anything and still consider it a “quick reference”, so you’ll need to understand at least a little bit of UML for this to be worthwhile. You can check out a quick reference for UML here and here.
This is a free download – you just have to have a DZone account.
You can also get design patterns gear (shirts, posters, etc.) here.
