As far as i can decipher , we impose Object oriented paradigm in
kernel space using C  : like using gates to allow only one way entry
and binding functions to structures in a OOP fashion  and trying to
make them private to that structure only  , encapsulation of one
struct into another structure (and lots of features ) and itself  lots
of kernel subsystem supports like driver interface and blah blah
behaving like **objects** .......
    

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.

  

why dont we use some fully OOPs supportive language like JAVA or
partial supportive language like  C++ to construct Linux Kernel????
    

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.

  

I don't  think that performance is the main reason behind all this .
Is it??
    

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