Correct me if I'm wrong. But you'd only need to synchronize if the method
used data that was shared between threads. If you have a method:
public static int getMonth(String date)
{
return dataFormatter.parse(date).get(Calendar.MONTH);
}
or something like that (I can never remember the exact api), then you wont
need to synchronize it because its not using anything (except the
dateFormatter object) that is shared. I cant see where you would need
synchronization there.
The exception to this is the situation where the argument is mutable (which
String is not) and other threads may be changing it, in which case you might
need to synchronize on the argument. But I cant see why you would
synchronize a static method as a rule of thumb. If its a utility method,
then let the calling class do the synchronization of the data.
I'd like to see someone point out where I am wrong if indeed I am.
thanks
