O'zgaruvchan (17-ma'ruzadagi misol)

Umuman olganda, 17-ma'ruzada c misoli bor volatile, unda aytilishicha, agar o'zgaruvchi isCancelishlatilmasa volatile, bu o'zgaruvchining qiymatlarini boshqa ipdan o'zgartirib, boshqalar bu haqda bilmaydi, men misolni qayta yozdim, faqat usulda runipning nomi va qiymati ko'rsatiladi isCancelva ma'lum bo'ldiki, o'zgaruvchining mavjudligi volatileyoki yo'qligidan qat'i nazar, qiymat barcha oqimlar uchun o'zgaradi, hatto siz taqillatgan bo'lsangiz ham, men butunlay sarosimaga tushaman; agar men sinxronizatsiyani aniqladim, keyin men volatilesarosimaga tushdim va uni hech qanday tarzda qo'llay olmayman. Ehtimol, men qandaydir tarzda misolni noto'g'ri yaratganman? Men ham sinf yaratishga Clockva dan meros olishga Threadva mainikkita misol yaratishga va ikkalasini ham ishga tushirishga harakat qildim, u ham volatileishlamadi, menga yordam bering, aks holda aqldan ozaman)
