anche a me ieri lo diceva, era un errore di parentesi forse, o forse hai dichiarato ad es:
private double a, b, c;
invece di private double a;
private double b;
private double c;
a me lo diceva per uno di questi motivi!!

"Cilindro should be declared abstract: it does not define setParametri(double[]) in Figura3D at line 52"

quindi devo ridefinire setParametri anche nelle classi delle figure?

Beh, ho fatto una serie di if per controllare il tipo dell'oggetto. Ovviamente mettendo prima le classi che estendono le altre.

Questo però non funziona nel caso io definissi una nuova classe che estende ad es. Parallelepipedo perchè non c'è il relativo instanceof nel metodo equals()...
E' questo che non capisco, se bisogna fare una cosa tanto perchè vada con il file di esempio oppure una cosa carina...
