This has been discussed before on this list, and FWIW, this is not
technically true. Java only does pass by value; but it just so
happens that when an Object is a function argument, the value that is
passed is its reference. One might argue that this is a meaningless
distinction, but it does mean that Java does not behave according to
the technical definition of pass by reference (e.g. you can't write a
swap function the way you can in languages that do pass by reference).
But it does allow you to write functions that can modify their Object
arguments, in certain cases. Strings, however, are immutable
(i.e. unchangable), so that is not one of the cases.
Now, it's unclear what exactly the original poster is trying to do, so
without more details, I don't know how to provide this information to
their situation.
