Similarly, every time the variable is written, the value
must be stored in main memory. Since these operations are atomic,
we can avoid the race condition in our example by marking our done flag as
volatile.

Similarly, every time the variable is written, the value
must be stored in main memory. Furthermore, Java specifies that the
load and store operations are atomic for volatile variables, even for long and
double variables. Hence, we can avoid the race condition in our example by
marking our done flag as volatile.

We've already seen that in one case the answer is yes: you can use the
volatile keyword for an instance variable (other than a double or long).

Of course, the balance is very one sided; volatile variables can be safely used
only for a single load or store operation and can't be applied to long or
double variables. These restrictions make the use of volatile variables uncommon.
