OOP is a design issue independent of the used programming language. So
you actually *can* do OOP with C (or assembler or ....) and I have seen
C++ programs which do not employ the ideas behind OOP.

What does it buy and what does it cost?
For - or more against - Java: You really do not want an OS to use an
interpreted "language". That kills performance. And the more interesting
challenge is to implement hardware IRQ handlers in Java.
C++ has lots of features which make it awkward to use. For starters,
think about the fact that Java does not have multiple inheritance.

Did you google for it and read the links etc.?
You will find much more on this question.
