java kod....pomozite!!!Trebam pomoć...vjerojatno kao i većina ovdje
...trebam za ispit iz jave napraviti aplikaciju....uglavnom,aplikacija je kompleksna,a ja imam problem samo s jednim njenim djelom, tj prozorom...da objasnim...radi se o tome da korisnik bira hranu i piće koje želi naručiti..prvi combobox nudi slijedove jela...kad se odabere jedan slijed, drugi combobox nudi hranu koja spada pod taj slijed jela...npr.neko hladno predjelo...ja sam to napravila,al ono što želim dalje napraviti,je da kad korisnik izabere neke jelo iz tog drugog comboboxa da se ispod pojavi slika tog jela i sastojci (isto vrijedi i za piće).....uglavnom,to nikako ne mogu postići...pa molim sve ljude dobre volje da mi što prije pomognu....šaljem kod (napomena...radim u eclipsu.)....PUNOOOOO HVALA!!!!...import java.awt.*;
