Pocetnik sam u javi, ali sa velikim znanjem C++. Ovaj primer je iz Deitelove knjige (prepravljen) da radi pod Eclipse 3.2 i jdk 6. U knjizi koriste printf isto kao u C++, ali to ne radi...
Na ovo resenje sam "nekako" nabasao, ali sam ubedjen da postoji elegantnije...
Svaka pomoc i savet su dobrodosli...
