ho scritto una classe che ha due file di input i cui nomi sono del tipo "nome_file.xml" e "proto_nome_file.rdf" e due file di output i cui nomi sono del tipo "nome_file.html" e "nome_file.rdf".
così come l'ho scritto però, ogni volta che lo eseguo devo specificare i nomi dei file di output d tastiera.
considerando che i file di output hanno lo stesso nome di uno dei file di input, fatta eccezione per l'estensione, come potrei fare in modo che una volta scelti i file di input, i nomi degli output vengano salvati automaticamente cambiando solo l'estensione di questi ultimi?
posto il codice...grazie a chiunque mi aiuterà.
