pass by reference problem?

[harsh garg]

in pass by reference we generally pass class name and it's object,like this way can we pass interface and it's object?

you can declare interface reference as a parameter . and you can pass a object which implements the interface . and also you cant instantiate an interface

Hi,

You can declare Interface and its reference in parameter list as

  methodX(InterfaceName referenceName) {} 

, to this method you can send the object references which implement this Interface.

Thanks,
Rakesh.

If you pass by reference you aren't writing Java. Java works entirely on a pass-by-value basis. We have an FAQ about that. You can also do a search on this forum and you find all sorts of useful things about it, including my post in this thread, which has some useful links to other threads or resoures.
