Ta funkcija nizu dodeli novo vrednost in nadomesti vso njegovo trenutno vsebino.
Sintaksa
Razmislite o dveh nizih str1 in str2, sintaksa bi bila:
Str1.assign(str2);
Parametri
str: str je objekt niza, katerega vrednost je treba dodeliti.
t ff
podstavki: Določa položaj znaka, ki ga je treba kopirati kot podniz.
sublen : Določa število znakov niza, ki jih je treba kopirati v drug objekt niza.
n: Število znakov za kopiranje.
ch: Vrednost znaka, ki jo je treba kopirati n-krat
preverjanje ničelnosti v Javi
Povratna vrednost
