calendario in eclipse

[roby92gs]

Ehi ciao a tutti.. ho implementato questa parte di codice consultando il web per creare un sistema calendario gregoriano.. ma purtroppo mi da svariati errori, qualcuno saprebbe dirmi cosa manca?
Qui sotto c'è il codice seguito dai relativi errori
grazie in anticipo
