And you quote wikipedia as a "trusted source"? No wonder you're such an
idiot.
 
There is the truth, then there is Wikipedia. Occasionally they agree.
But most of the time Wikipedia is just someone's opinion - and you have
no idea just how knowledgeable that person is.
 
Composition is a "has-a" relationship. Inheritance is a "is-a"
relationship. Two entirely different concepts. But I know that's too
deep for your miniscule brain - as you've proven in this newsgroup over
and over again.
 
But hey - you're the expert in programming, OOAD, psychology - what
next, the Unified Field Theory?

Your fractal wrongness continues unabated! I like consistency! :)

Seems that you two are exchanging too lot of ad hominems and signal to
noise is therefore rather low. Do you have fun?

That "composition over inheritance" is IMHO a mantra. It has a kernel
of good truth in it but that is turned into religious slogan. Religious
slogans are considered harmful.
 
Inheritance is fundamental to object oriented paradigm; composition is
fundamental to any software design paradigm. So inheritance is misused
lot more often than composition. We can not solve a OOP question if
square is kind of rectangle or not by uttering such religious slogans
and suggesting that rectangle is component of square. ;)

FWIW, I recommend the excellent book:
 
https://books.google.com/books?id=_xvnuFzo7q0C&pg=PA82&lpg=PA82#v=onepage&q&f=false
(linked to a relevant section)

Damn! the link above does not seem to work now.
Oh well, here is the book, but the relevant section
does not come up:

Sorry about that non-sense! ;^o
