Re: Thread safe instance variables

[Jim Mason <jmason900@xxxxxxxxx>]

Hi.

Yes.  IF a bean can be updated in multiple threads,
then a setter for an instance variable could be
synchronized to ensure only 1 process updates it at a
time...  You can always pass parms to a method and use
local method variables that "thread safe" because they
are only used in the stack...
