#elon E'lon ❗️❗️❗️ PROGRAMMERS kanalimizda Qudrat Abdurahimov tomonlaridan ishlab chiqilgan elektron qurilmadagi masalalar to'plamini Java dasturlash tilida ishlashni boshlaganmiz. 20.05.2022 (juma) kuni Kiritish, chiqarish va o'zlashtirish operatoriga oid masalalar (Begin) bo'limini yakunladik Ertadan 23.05.2022 (Dushanba) kunidan boshlab, Java dasturlash tilida Integer bo'limini boshlaymiz. Misollar tartibi quyidagicha. Ertalab soat 08:00 da misol tashlaymiz, kechqurun soat 20:00 da o'sha savolni javobini Java dasturlash tilida ishlanishini tashlaymiz.
