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

متل هيك void swapFirstLast() { node* helpPtr = head; if(head==nullptr) { int value=head->data; cout << "Error : cannot swap(the list has less than two nodes)"; } int temp = helpPtr->data; while (helpPtr != nullptr) { if (helpPtr->next == nullptr) { int value = helpPtr->data; helpPtr->data; } helpPtr = helpPtr->next; } node* helpPtr2 = head; helpPtr2->data; };

لما بدي ادخل زيرو احتاج انو يطبعلي انو الليست فاضية وانو باقي العمليات ما حتتنفذ لكن ما بيحصل هيك ايه المشكلة

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
