Anche io, non in tutte le classi, ma solo nelle tre superclassi ed in Cubo, ma poi dipende da come costruisci gli oggetti....

Idem..

Implementare Comparable non è richiesto nè necessario a mio parere...

Se costruisci un Parallelepipedo 1*1*1 ed un Cubo 1, a livello geometrico le due figure sono uguali, ma per le specifiche, sono diverse.

Quindi, se fai un aricerca di un Cubo 1 e trovi anche il Parallelepipedo 1*1*1, è un errore.

Intendo dire che nel file Figure3D.txt non abbiamo già una situazione simile? in altre parole se il risultato da noi ottenuto è uguale a quello di Grossi il problema non dovrebbe porsi....

una considerazione:

se uno estende la classe parallelepipedo, penso che non dovrebbe scrivere all'interno di tale classe alcun riferimento ad altre figure; giusto ?

se ora immaginiamo di scrivere una classe "pippo" compatibile con parallelepipedo, non si deve aprire la classe parallelepipedo per sollevare una eventuale eccezione che si verifica nella nostra nuova classe "pippo", giusto ?

il fatto non è questo

pensa se la classe parallelepipedo l'avessi scritta io e la devi adattare tu al tuo caso in specifico

se apri la mia classe cade il discorso della potenza di java

p.s.
se nò era troppo facile :D
