OO Logo Every now and then when I review code, I see developers write code that does not conform to the basis OO design principles and this eventually make it difficult to understand, maintain, extend blah blah..... Basically its just keeps on adding a layer of un-necessary complexity that you have to deal with. So what do you do? I guess you end-up refactoring the code( Did I said, I love refactoring? Yahooooooooooo) following basic principles and design patterns, this takes time and effort so why not try to do it right in the first place.

So I thought I would capture these principles and have the developers understand and follow it their future development. These are time tested principles that one should not shy from applying at the very begining. So think and design and then code but not just code.

I sat down last night and wrote some code to help brush up on implementation of some of these concepts. The code is what I remember from what I call the 'classic shapes' example. An early mentor using the 'shapes' example to demonstrate many of these concepts back in the C++ days, so its still one of my favorites. Others have been the automobile (transport), animal, etc...but shapes is still my favorite because way back then it carried over into a hobby of mine: video programming.

However, that graphic is pretty darn sweet ...
