"Document” is custom class (i.e. a class that you build), which contains a text (implemented as an ordered collection of strings). It has methods "addString" (which appenda a String at the end of the Document) and a method "toString" (which overrides the toString method of the Object class), useful to print out the whole Document.

A server shows a remote method “validate” with a parameter of type Document. The method adds the string "Validated on " date in the Document.

A client will create a Document, and ask the server to add the timestamp. At the end the client prints the content of the Document, which of course will have to contain the validation.

NOTE: Before embarking in the project execution, I strongly suggest to follow the Oracle tutorial on Java RMI: http://docs.oracle.com/javase/tutorial/rmi/overview.html

Also the following tutorial may be useful: https://www.tutorialspoint.com/java_rmi/index.htm.
