    which one is best volatile or Atomic?

    I use a shared flag between threads. I am really worry about the performance of updating/getting a boolean flag, whether it is volatile or Atomic?

    Tell me which one is best volatile or Atomic?

    Usually for synchronization atomic access is used. And variable declared as volatile, will have atomic access by default.

    If you just need the values between threads, you might want consider using a static variable.

    In any case, Official JAVA page for your atomic doubts.
