№	Ajdod class va uning maydonlari	Voris class (ajdod class maydonlaridan foydalangan holda)	Obektlar massivini yarating. Murakkab saralash algortimlaridan foydalanib saralash metodlari yarating. (saralang o’sib borish tartibida yoki kamayib borish tartibida va alifbo tartibida)
11.	class tovar: nomi, narxi, chiqarilgan yili	class dori_darmonlar; saqlanish_muddati	Array konteyneridan foydalanib ishchilar dori darmonlar ro’yxatida chiqarilgan yili bo’yicha saralang.
