مساعدة بمشروع ادارة مكتبة

اولا لابد وان تبدأ بعمل الـ database

ثم analysis document

ثم تصميم الشاشات (design)

ومن بعد ذلك تبدأ فى عمل الـ كود والـ Data access object

الذى يربطك بالداتابيس اضافه وتعديل وحذف

والله الموفق والمستعان

محاولاتك

والمشاكل التي تعاني منها

تحياتي

اخي محمد انا ما بدي جافا سكربت .. ولكن كود عادي من غير واجهات رسومية او GUI

اخي علاء انا بدي داله لكتابه كلمة مرور لمدير المكنبة واخري للطالب مع تحويل حروف كلمة المرور الى نجوم

هو مشروع بسيط .. انا بدي احفظ الكتب بمصفوفات فقط

انا عملت هاد الكود .. بس باقي الدوال مش عارف اعملها !!

            } catch (InputMismatchException error) {
                System.out.println("@TEST@ <<< 5- Breaking from main while loop... >>>>");
                break exit;
            }

        }//end of while loop.

        System.out.println("####  You have Exited the Library!  ####");

    }//End of run() method.
}

ما في ميثود اخرى نقوم فيها بحفظ بعض الكتب مسبقا .. ثم اذا اردنا اضافه كتب لها وتخزينها بالمصفوفه

لأن انا مش عارف كيف ممكن احفظ معلومات الكتاب مسبقا (يعني تكون مخزنه مني انا )

   public String displayBook() {

        String BookInfo = "----------------------------"
                + "\nTitle:.................." + title
                + "\nAuthor:................." + author
                + "\nPublisher:.............." + publisher
                + "\nPublicationYear:........" + publicationYear
                + "\nStatus:................." + status
                + "\nBorrower:..............." + borrower
                + "\nDate Borrowed:.........." + borrowDate
                + "\nReturn date:............" + returnDate
                + "\n----------------------------";
        return BookInfo;
    }

جرّب

Book b = new Book();
		Book b1 = new Book();
		Book b2 = new Book();

		Book[] obj = {b,b1,b2};
