Topshiriq

1. Java dasturlash tilida foydalanadigan kalit so’zlarni xatolikga tekshiruvchi dastur tuzing (misol uchun : Kiritiladigan qiymatlar: for, wile, do natija: while kalit so’zini kiritishda xatolik mavjud ).

2. Fayl ochish, o’qib olish dasturini tuzing va albatta faylga nom berishda paskal ko’rinishidan foydalaning.
