rebind() of the Naming class(found in java. rmi) is used to update the RMI registry on the server machine. Naming. rebind(”AddSever”, AddServerImpl); lookup() of the Naming class accepts one argument, the rmi URL and returns a reference to an object of type AddServerImpl.

I’m sorry, but there seems to be a misunderstanding. As of my last knowledge update in January 2022, there are no rebind() and lookup() methods in the Naming class in Core Java.

In Java, the Naming class is typically associated with the Java Naming and Directory Interface (JNDI), which is used for accessing and managing distributed directory services. However, the standard Naming class does not have rebind() or lookup() methods.

If you have a specific context or library in mind, please provide more details or check the documentation for the correct information. It’s possible that the methods you mentioned are part of a custom implementation or a specific library that extends the functionality of the Naming class.
