Does Java call by reference or by value?[resolved]

I always thought that Java called things by reference because it calls the address and not the value itself, but according to my lecturer it always calls by value, which seems a bit strange to me. Just wondered if someone could explain how it is that Java always calls by value

I think Java passes its primitive data types such as int, char, double, etc. by value whilst it passes arrays and objects by reference. Strings can be considered as byval since a String cannot have its value updated, with the new value returned.

But I'm no Java expert...

But you're exactly right. :)

Cool as!

Shows I have some uses then. That's the only post I've felt competent enough to make in here - I didn't know if I was talking complete bollocks or not, but I'd thought I'd take the risk to help Pix out.... :)

Thank you :)
