Can i modify the interface sun providing

[woo hwang]

Hi all,

I have a question about the Interface Sun provided.
When I implements RMI, I reliased that i need to thorw RemoteException for all method in the SUN provide interface.

What i am wondering is that can i change interface??
can i throw more exceptions in the sun provided interface?

Cheers

The one of the must conditions is the original interface should not be altered. You can extend the interface and throw your own exceptions and rmi exceptions.

Simply... No. I mean if you add custom exceptions then you are now programming to an implementation rather than an interface (if you are confused or unsure or never ehard that OO principle, I can suggest Head First Design Patterns).
