does your code came from different java files?

I dnt knw what you mean but if you are asking if my program has different segments yes it does..i got this prog from book which i am following

I don't know what you mean by "segments" but from your example, you should have three separate source files: AddServerIntf.java, AddServerImpl.java, and AddServer.java.

And your error messages are coming from AddClient.java, the source of which you have not posted. Also, please use CODE tags when posting code.
