Yes, of course! Did you see my Answer: no out or ref in Java, only by value? There is a work-around.

Java does not support out parameter; all parameters are passed by value, but a parameter can be of mutable reference type, in this case, even though the instance of a parameter can not be modified referentially, the object itself can be modified inside the function and returned modified.

See this: http://www.javacamp.org/javavscsharp/outparam.html[^]. A primitive or immutable type can be modified as a result of call by wrapping it in a class or passing it as a reference of array (which is a reference type and mutable.

See also about mutable and immutable objects: http://www.javaranch.com/journal/2003/04/immutable.htm[^].
