Adding fuel to the fire, note that [lang] 3.0 will include the Pair class.

True, you shouldn't synchronize on any object that A) you want to change and
B) can only be changed by being replaced by a newly constructed object. If
Integer, for instance, had a setter method, then it could still have been
used in this way. However, it seems to be immutable. I generally just
Actually, funkyChanger will not work because you are effectively
reassigning the argument. Since all arguments in Java are passed by
value, the assignment is not realized by the caller.
The only ways to get argument changes surfaced to the caller are using
a typed return or passing in an argument

All objects are passed as references in Java.
All fundamental scalar types have Object wrapped versions.
An argument that is meant to be modified just needs to be an object
reference.
So, you can simply go from:
void funkyReader(int arg) { arg++; }
to:
void funkyChanger(Integer arg) { arg++; }

Thank you all guys! You 're amazing!
If you only use boolean, integer and long, you can also use AtomicXXX
from java.util.concurrent.atomic (if you have to use them in a
multi-threaded environment).
Otherwise, the MutableXXX wrappers in Commons Lang are good.

Michael,
Primitives are passed by value in Java. If you want to "modify" primitives,
use the MutableXXX wrappers in Commons Lang.

I mean exactly the same thing as C# but from the replies i see that's a
difficult task and also that has little to do with apache commons... Because
i use java a lot it's annoying the fact that specific variables that i want
to change values in other functions cannot be passed as arguments but

Actually it sounded to me as though he was talking along the lines of Mutable*
in [lang]. :/

And excuse my rather bad C# code which doesn't compile... been
spending way too much time in scripting languages lately.
