Not the way I see it. Java has primitive constructs, which are not OOP.

Additionally, it has static class members, which I don't consider to be OOP
either.

I understand that the next revision to the language  will provide transparent
wrappers for the primitives - making them essentially indistinguishable from
objects - but it hasn't got them yet.

Java is reasonably close to OOP, but not 100%.

And a good thing too, probably. Pure OOP languages aren't exactly taking the
world by storm.
