في حالة بدي اعملها بدون فايل بجافا ممكن وكيف ؟

عملت واجهة تسجيل دخول بدي اعمل كود يتحقق من اليوزر والباسوورد وينضافوا في ملف واذا كان تسجيل الدخول صحيح يحولوا على الويندوز الاخرى واحتاج مساعدة وشرح كيفف ممكن بدي اعملها

قمت بتجربة الكود ولكن يحتوي على العديد من الايرور

هل تعمل معك هذه الطريقة؟

ما بيشتغل معي يا ليت تفرجيني بعد اذنك

بدي من اليوزر انو يدخل 3 digits octal ويحولن الى رقم عشري ممكن مساعدة كيف بدي اعملوا ككود بالاسمبلي

كيف استدعيها طيب؟ وبالنسبة للقائمة فين حتكون في كلاس البرودكت او في الميثود الخاصة CreateOrder?

بالنسبة للملف تبع customers ايوا موجود وبيشتغل معايا وبشوف بيانات العميل بالنسبة لاستدعاء الدالة CreateOrder هيا case 4 في main class بالنسبة للنقطة الاخيرة اعملها كذا Arraylist<Product>list2?

من المفترض انو لما ينتهي العميل من ادخال البيانات حقتو واختيار الطلبات تترسل المعلومات لل createOrder ولما بستدعيها حتتطبع معلومات العميل والمنتجات المختارة والسعر الاجمالي للمنتجات بيطبع معلومات العميل ولكن المشكلة انو ما بيطبع جميع المنتجات اللي اختارها العميل ولا بيحسب مجموع السعر الكلي للمنتجات المختارة

وطيب ومشكلة عدم طباعة المنتجات كاملة اللي اختارها العميل؟ فقط بيطبع المنتج الاخير اللي اختارو العميل

انشئت ميثود create order ومن المفترض بعد ما بيختار العميل الطلبات بتترسل معلومات العميل المدخلة والطلبات المختارة الى هذه الميثود وحساب السعر الاجمالي ولكن المشكلة انو بتطبع الطلب الاخير اللي اختارو العميل ما بتطبع كل الطلبات وايضا ما بتحسب السعر الاجمالي ايش الحل؟ //main class import java.io.IOException;

عملت الميثود وبتشتغل معايا ولكن المشكلة بتاخذ منتج واحد مش كل المنتجات اللي بيختارها العميل //main class

كلاس الفاتورة يتضمن ميثود Create order واحتاج منها تستقبل من كلاس العميل المعلومات اللي بيدخلها ومن كلاس المنتجات المنتجات اللي بيختارها العميل وفي النهاية يحسب الاجمالي

احتاج مساعدة في التعديل على ميثود تستقبل ايضا بيانات العميل اللي بيدخلها
