a thread contacting m2 could study 0, 1234567890L, or Several other random benefit because the statement i = 1234567890L will not be sure to be atomic for a long (a JVM could publish the first 32 bits and the last 32 bits in two operations plus a thread could possibly observe i in between).
Virtually, yes. "Atom" arises from greek "atomos" = "uncuttable", and continues to be Employed in the sense "indivisible smallest device" for an extremely while (till physicists uncovered that, the truth is, you will find
