مبدل تاریخ میلادی به شمسی:

یه مبدل تاریخ میلادی به شمسی برای جاوا کارها!

ببخشید! من سورس رو ضمیمه کردم ولی مثل اینکه ضمیمه رو نشون نمیده! پس این هم خود سورس:

با عرض ادب:
بسیار جالب و مفید.
دستت درد نکنه.
فقط جالب تر بود اگر موقع تایپ وسط تگ code می گذاشتیش.

یه عشق برنامه نویسی خفن

سلام
تگ رو گذاشتم قبول نکرد.
راستی مثل اینکه داونلود برای اعضا کار میکنه!

:D
i dont know java at all
but it's god
i can't type parsia :oops: n.

لطف کنه یکی از دوستان کلاس compile شدشو اینجا قرار بده
با تشکر

سلام
این کد مشکل داره 4 روز عقبتر معدل شمسی رو میده .
اگه فایل جاوا رو upload کنید بهتره .

دوستان بد نیست سری به این تاپیک بزنید.
