Hm ... čini mi se da if
uvijet možemo opisati ovako (pseudokod):
AKO polje nije prazano
I AKO polje ne sadrži nedopuštene znakove
> polje nije ispravno
Validacija se dakle ne bavi time je li neko polje popunjeno ili ne, već da li sadrži nedopuštene znakove.
Promatrajući funkciju koja određuje sadrži li polje nedopuštene znakove vidim da i ona prvo provjerava je li polje prazno, tako da je suvišno to još jednom provjeravati. Dovoljno je dakle provjeriti je li fieldLength == -1
.
Unatoč tome što se ista stvar 2x provjerava, ne vidim da je to neka greška.
Jedino što mi je čudno jest da niti jedno polje nije obavezno.
