This is incorrect. Changes made to a boolean that is not volatile may
never become visible in another thread.
Sorry, I didn't read the question carefully. You are right David.
What I meant is that a volatile boolean is clearly protected, as you
can't apply simple opration like ++ or -- on it. I don't know about :
volatile boolean b = Boolean.TRUE;
...
b = !b; // Might fails if used in a concurrent portion of the code.
