In this case, it would mean to create classes with just program logic and no
user I/O from the classes with user I/O. For example, the servizio method
c_Elenco currently writes a list of files to System.out. The program logic
here would be getting the list of files. The user I/O is printing them to
System.out. A class used for a SOAP service might have a method that
returned the list of files in an array. There might then be a class used by
the client application that would call this SOAP method to get the list,
then print the file names to System.out.

Do not send e-mail directly to this e-mail address,
because it is filtered to accept only mail from
specific mail lists.
