Shouldn't this be public? How else can it be accessed from the outside? Or did i miss some trick? :)

Thanks for responding, but this doesn't quite do the trick. I think i have to elaborate on what i want. From what i wrote previously, i don't think it came out clearly.

I have a package, foo, containing the Counter class. Now i have a class, A, which does: import foo.Counter;

A has a main method, which starts an instance of itself, wrapped in a Thread. The Thread works as a ticker, counting the shared object Counter up one.

Now i start another instance of A, from another shell. Since this does the exact same thiing as the first A, it also imports foo.Counter. What i want is for the second instance to start counting from where the first instance was at when the second was started.

An example printout would be like this:

(Start A1, first instance of A, with java A)
A1: count: 1
A1: count: 2
A1: count: 3
(start A2, second instance of B, in another shell, with java A)
A2: count: 4
A1: count: 5
A2: count: 6
A1: count: 7

And so on...

From what i tried, A2 just starts counting from 1, and A1 just keeps counting.

Any suggestions on how to crack this one? :)
