+# Programming-Java
+حل بیش از 300 مسئله و پروژه با زبان جاوا
+Problem Solving with Java (more than 300 problem and project)
+
+در این دوره سعی شده است بیش از 300 مسئله در زبان جاوا به صورت کامل نوشته شده و در صورت لزوم رفع خطا شده و مرحله به مرحله شرح داده شود. 
+پیش نیاز این دوره ، فاز 1 آموزشهای من می باشد. در این دوره آموزشی الگوریتم و نحوه پیدا کردن جواب مسئله هدف نیست. برای درک کامل الگوریتم مسئله ها باید فیلمهای فاز 1 رو مشاهده نمایید. 
+در این دوره هدف فقط نوشتن و جواب گرفتن از مسئله ها می باشد. 
+مرجع سوالات ما در این آموزش سوالات ورژن 1.4 من می باشد که در آدرس زیر قرارداده شده است. 
+
+آدرس دانلود سورس کدها : 
+https://github.com/gClassAcademy/Programming-Java
+
+کلیه منابع دوره ، سوالات و دی وی دی دوره درآدرس درس توی وب سایت من موجود می باشند :
