Static method

[Paul Medford]

I have a doubt now...
Say you have a util abstract class with static methods. Whenever a method is called, is it thread safe? or is there a chance that the same method be called more than once at the same time and corrupting the data?
Simple question, but I'm kind of puzzled...
Thanks,
Francois

Hi Francois,
The only way to make a method thread safe is to make the methods synchronized.
Example (thread safe ):
java.util.Vector
Example (not thread safe):
ArrayList

Or make sure that you only access local variables in it and not access any instance or class variables.

Thanks, it's what I thought. I just had a doubt, somehow...
