Are Local Variables Thread Safe

Hi,

Are Local Variables Thread Safe , even if the method is not synchronized.

Two threads executing same method will have their separate copy of the local variables.

Yes, but it is possible for two local variables (references) to point to the same objects -- so it is not guaranteed to be thread safe.

Add the synchronized keyword to the method doesn't guaranteed threadsafe either -- as you need to have a synchronized object that is used by all accesses (that are not threadsafe).
