Sorry for my vagueness...
In C++ I can do:

routine(int & modifedByRoutine) {modifiedByRoutine = 6;} // pretend 
\\ this is a method, not a stand alone function

main()
{
int someInt = 2;
  routine(someInt);
// someInt equals 6 now
}

Now, how to do this in Java, i.e. make the parameters return something
"changed" to the calling environment

Thanks for your patience,
