دوستان عزیز سلام
من برنامه ای نوشته ام که در ابتدای اون به یک مشکل برخوردم و اون هم اینه که در اولین متد که خواندن از فایل تکست هست مشکلی وجود داره و من نمی دونم کجاست.
داده ها رو تک تک از فایل باید بخونه و بعد از یک کلاس آبجکت بسازه و در یک آرایه ذخیره کنه اما نمی کنه. نمی دونم مشکل پر شدن آرایه ار کجاست که پر نمی شه. ممنون می شم اگر کمکی بکنید. در زیر کل کد رو می تونین ببینین. :لبخندساده:
