“Kinofilm” classini yarating. Maydonlari: Nomlanishi, Rejessor, davomiyligi (minut da), aktyorlar soni. “Narx” nomli virtual metod yozing, kinofilm narxi quyidagi formula orqali hisoblanadi: davomiyligi * 20 + aktyorlarning soni * 30, lekin agar rejissori = “Stiven Spilberg” yoki “Djeyms Kemeron” bo’lsa narxi ikki barobarga qimmat bo’ladi. Shuningdek, film haqidagi ma'lumotlarni ekranga chiqaruvchi “Axborot” metodini yozing: Nomlanishi, rejissori, davomiyligi, aktyorlar soni va narxi. Bundan tashqari, “Multifilm” avlod classini yarating. Qayta yuklangan “Narx” metodi formulasi quyidagicha: davomiyligi * 25 + aktyorlarning soni * 10 (rejissyordan qat'i nazar). Asosiy dasturda 2 ta film yarating rejissori “Stiven Spilberg” va “Jorj Gofman” filmlari, multifilm yarating va ular haqida ma’lumotni chiqaring.
