Java does not have “global” variables. All data access is via a Class, and then possibly and instance of a Class. Contrast this with “globals” in C - the variable - if declared external is visible to all code anywhere (there are more modern ways to namespace this for some level of protection).
When declaring a ThreadLocal in Java, it still must be accessed using the Class or instance accessor, which also means, since you can control private/protected/package level access, you can prevent unauthorized/uncontrolled mutation - this is completely different than historical "globals” and the problems surrounding them. > On Jan 17, 2019, at 2:19 PM, Ian Denhardt <i...@zenhack.net> wrote: > >> They are not global variables, they are class variables.
