Well, I'm not saying that OO doesn't make your code simpler and with better reuse but when you google "advantages of OO" those advantages are comparing OO with what?
Also, I'm not saying that FP is better, I've only stated what were the benefits I've got when I applied some FP concepts on top of my usual OO programming. Though I have to say that there are some caveats... one of them is the difference between "tell, don't ask" of OO and "ask, don't tell" of FP. Java is an OO language and retrofitting some FP concepts on top, makes you wonder if you're really doing the right thing. On 14 July 2010 17:36, Jan Van Besien <[email protected]> wrote: > Funny...
