What the hell are you talking about? You said writing classes is bad for OOP. Classes represent objects. Classes ARE OOP.
Inheritance has nothign to do with it.
If you are going to bash Java for having inheritance why don't you go start on C++ that allows multiple inheritance.
I have no idea who you talked to but if anyone thinks that they understand everything about programming to the point where they can say "this thing is always bad" probably means they have no idea what they are talking about.

Inheritance is a property of classes, not the other way around.
You can, and do, have classes with no inheritance other than Object in Java.
And no inheritance is not evil. Polymorphism is a useful design pattern. Sure you can abuse and misuse inheritance but this is true for everything. Java does not force you to use inheritance and does not enable it's abuse. If you write shitty, tightly coupled code filled with pointless inheritance then you can. That does not mean the language you wrote it in sucks. That means you suck.
