أحتاج للمساعدة ضروووووووووووووووووووووووووووووووووووووووووووووووري ........

المشكلة التي واجهتها :resentful: ......هي :

أنه عند إدخال المستخدم اسمه أو رقمه لا تظهر لي القيمة بل يظهر لي (null) في جميع الحالات :cry: .... وأنا لا أعرف لماذا ........

...... أرفقت حلي ... والأسئلة أيضا ليكون المطلوب واضحا بشكل أكبر :calc: ....... أتمنى المساعدة بأسرع وقت ممكن ..... :unsure:

وشكرا أخي لإهتمامك .... جزاك الله ألف خيــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ

(3) Rename the class Responder to be PhoneDirectory and remove the method: fillresponse(). Modify the method: fillResponseMap() so that it will read one line from the ReadTextFile object (from the file: Phone_Directory.txt), separate the line to three string: Name (string1), Phone Number (string2), Address (string3), and store them in two HashMaps using:

responseMap1.put(string1, string2 + string3); and

responseMap2.put(string2, string1 + string3);

Repeat the reading until the end of the file “Phone_Directory.text” so that the two HashMaps will be filled with the required responses.

(4) Rename the class: TechnicalSupport to PhoneDirectoryManager and use static void main method.

(5) Your program must read an input string from the user which contains either the name of the person to get his/her phone number and address or the phone number to get his/her name and address. Accordingly, your program have to reply correctly to the requirement of different input string. If there is no name or no phone number match the input, you write a message to inform the user that this name or phone number does not exist and ask him/her to input another name or phone number or input bye to exit the system.

(6) Don’t forget to change the welcome statement and the goodbye statement too.

Documentation is very important in this assignment. You have to write full documentation for each class used.

أتمنى المساعدة ...... ضروووووووووووووووووووووووري قبل الساعة11

أختي أخبريني ما الذي يقوم به البرنامج بالضبط

لديك دليل تليفونات ما المدخلات التي تأخذيها من المستخدم؟؟؟

حاولي الإسراع فأنا أحاول مساعدتك

تحياتي

جزاك الله ألف خير أخي علاء الصالحي على تفاعلك .....ومحولتك مساعدتي .....

.... المطلوب هوأنه عند إدخال المستخدم إسمه ... يجب أن تظهر له معلومات عنه مثلا كرقمه وعنوانه .... وهي التي إدخلناها في HashMap

هذا ما فهمتـــــــــــــــــــــــــــــــــــــــــــــــــــــــــه ..... والله تعالى أعلم ....

>>>> أرجوا أن يكون المطلوب واضحا .............<<<<<

وأعتذر عن التاخير في الرد ........

وأكرر شكرري لكل من تابع و حاول مساعدتي ....

جزيتم جميعا كل الخير ....

هل انتهى الموضوع أم مازلت بحاجة إلى مساعدة؟؟

تحياتي

.... بصراحة يا أخي إنتهى موعد تسليم الواجب .......

ولكن مازالت المشكلة قائمة ..... سلمنا الواجب واتكلنا على الله ... نحن تقريبا أنجزناه كاملا ولكن كانت المشكله في الناتج .....

وننتظر أن نعرف أين خطأنا بتحديد ..... فإذا تمكن أحد أن يعرف المشكله لامانع أن يرشدنا.... لكي ننتبه ولانقع في هذا الخطأ مره أخرى ... لأن الامتحانات النهائية على الأبواب ....

(((دعواتكم)))

جزااااااااااك الله كل الخير أخي علاء الصالحي على متابعتك للمشكلة والشكرلكل من تعاون معنا وحاول أن يساعدنا .....

قال الله تعالى: وَتَعَاوَنُواْ عَلَى الْبرِ وَالتَّقْوَى وَلاَ تَعَاوَنُواْ عَلَى الإِثْمِ وَالْعُدْوَانِ [المائدة:2].

الدالة location في الفئة PhoneDirectory

ما الذي يفترض أن تقوم به؟
