Hi all
Can you please tell me whether static mehods/variables are thread safe? if not why not?

There's nothing about static methods or variables that makes them inherently thread-safe.

You can easily write some example code with two threads, in which the threads try to write to the same static variable at the same time, so that the end result is unpredictable - which demonstrates that it's not thread-safe.
