Quote: what's a good way to learn design patterns? The short answer is to buy a book, read it, and start looking for invariants in your solutions that can be mapped into patterns. But before you do that, make sure that you understand OOA/D. Patterns were enabled by the problem space abstraction provided by the OO paradigm so most pattern books employ OOA/D notations. For example, almost all of the patterns in the original "Design Patterns" book employ generalization, delegation, and polymorphic dispatch, which are fundamental OOA/D techniques. If you don't know such OOA/D fundamentals well, it will be quite a bit more difficult to recognize and implement patterns. -- There is nothing wrong with me that could not be cured by a capful of Drano.

Actually it should NOT depend on the language. That's why OOA/D has its own notation that is independent of computing space implementations. CUT ok sorry Lahman, I agree with you. I sent a fast response because I thinked that xeno searches to learn the design pattern in "operativity way". I don't code in C++: the example of "Design Pattern" of Gamma & C. are a little difficult for me. In Wikipedia a lot of examples are written in Java and I understood. If a person have never code in OO, I say the thier book is a very good idea. excuse-me for not-precision of language Back to top   Ads Advertising Sponsor H. S.

That's actually a pretty subjective evaluation. The Books category on my blog has some suggestions about how to go about picking a good one. -- There is nothing wrong with me that could not be cured by a capful of Drano. H. S.

Quote: object oriented analysis & design It depends of your programming language: if you code in Java or C++ you can download the book of Bruce Eckel. Actually it should NOT depend on the language. That's why OOA/D has its own notation that is independent of computing space implementations. OOA/D books that have a particular language in the title are almost invariably really books about OOP. (Meyer's OOSC was one of the very few OOA/D books that was oriented around a particular OOPL and still did a good job on OOA/D.) The OOPLs make major compromises with the hardware computational models that can be highly misleading and can encourage poor OOA/D practice. A lot of bad OO software has been written by people who moved directly from procedural development to OOP without bothering with OOA/D. In effect they write C and COBOL programs with strong typing because they overlaid Structured Design paradigms on the OOPL coding. -- There is nothing wrong with me that could not be cured by a capful of Drano.

The way they take you through the stuff is really cool. they haven't used boring theoretical way of explaining. It has touch of UML diagrams, cool images, discussion, questioning etc. Also it has questions at the end of each chapter.
