Note that in this case the OP is using STATIC on the method, not a
variable as far as I know.

Which simply means that the method my be called without an instance of
the class. Usually used for utility type methods that operate solely

also java.util.Random classes.

The thread safety of a method is not affected by the use of STATIC.

but if it's really a variable for an instance, or intended to work as a
local variable, you can run across a class of bugs that is very difficult to
