I don't know what "unwanted characteristics" java has as an OO language.
It is a pure OO implementation. And I agree with Mike - I think Java
is a much better language to learn OO programming.
And I've found the "bad habits", once you get into them, are very hard
to break. I don't know how many times I've had C++ programmers who got
off to the wrong start with OO programming and the result was a
horrendous mess of OO and non-OO code.
Smalltalk is also a great language for learning OO, but it's not used in
web programming.
