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

[ناصرقلی]

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

[mansoor]

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

[jeus]

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

[saeed_Z_F]

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.
