مساعده نظام مكتبة

عندي مشروع بسيط لنظام مكتبه كلاسات مرتبطه في بكج واحد 

المطلوب\\

The idea of the project is to create a very simple library system. that allows students to borrow books and return it within given date .

You are required to write these classes :

1-class Person with these data members :

Name ,Date of birth (date),Sex (char).

Methods:

ToSrting : to print the person information.

2-class student:

Name ,Date of birth (date),Sex (char),ID (string ), Specialty(string),and a list of borrowed books .

Methods:

ToSrting : to print the student’s information.

addBook:to add a borrowed  book.

ListOfBooks: to print the list of borrowed  books.

3-class Book :

 title (string), book no(string),author(string), Specialty(string), edition(string),borrowed or not (Boolean).

Methods:

ToSrting : to print the book’s information.

4-class Author :

name ,date of birth, sex, list of books.

Methods:

ToSrting : to print the author’s  information.

PrintList: to print the author’s  book

5-Borrwo interface :

Void Borrow(string bookno);

Void printreport(student s,list of book).

(You must determine which classes must implement this interface ).

The main should allow the user:

1-Adding new books to the library .

2- Loaning books to new students

3- Printing the list of b books of any author.

4-Printing the list of borrowed books of any student  .

5- Printing the list of b books in a specific topic .

6- Bonus :Printing a report after every Loan Process including :

The current data ,

Student name , id

Book no ,name ,edition

determine the returning date  “1 month “.

·         You should add all the needed setter and getter methods and constructors.

·         You should also override the methods equals, and  toString wherever they are

             needed.

·         Write the class diagram ,and  the sequence diagram for all classes.

اولا class Person

package person;
import java.util.Date;
/**
 *
 * @author hams4242
 */
public class Person {

   String name;
   Date date;
   char sex;

    public void setName(String name) {
        this.name = name;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public void setSex(char sex) {
        this.sex = sex;
    }

    public String getName() {
        return name;
    }

    public Date getDate() {
        return date;
    }

    public char getSex() {
        return sex;
    }

    @Override
    public String toString() {
        return "Person{" + "name=" + name + ", date=" + date + ", sex=" + sex + '}';
    }
   
   
}

ثانيا class student

public class Student {
   String name;
   Date date;
   char sex;
   String ID;
   String Specialty;
   Vector<Student> ListOfBookBorrowed;

    public void setName(String name) {
        this.name = name;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public void setSex(char sex) {
        this.sex = sex;
    }

    public void setID(String ID) {
        this.ID = ID;
    }

    public void setSpecialty(String Specialty) {
        this.Specialty = Specialty;
    }

    public void setListOfBookBorrowed(Vector<Student> ListOfBookBorrowed) {
        this.ListOfBookBorrowed = ListOfBookBorrowed;
    }

    public String getName() {
        return name;
    }

    public Date getDate() {
        return date;
    }

    public char getSex() {
        return sex;
    }

    public String getID() {
        return ID;
    }

    public String getSpecialty() {
        return Specialty;
    }

    public Vector<Student> getListOfBookBorrowed() {
        return ListOfBookBorrowed;
    }

    @Override
    public String toString() {
        return "Student{" + "name=" + name + ", date=" + date + ", sex=" + sex + ", ID=" + ID + ", Specialty=" + Specialty + ", ListOfBookBorrowed=" + ListOfBookBorrowed + '}';
    }
public void addBook(){
    
}
  
}

لكن ماعرفت للميثود addBook ,ListOfBook

ثالثا class book

public class Book {
String title,book ,author, Specialty, edition;
Boolean borrowed; 

    public void setTitle(String title) {
        this.title = title;
    }

    public void setBook(String book) {
        this.book = book;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public void setSpecialty(String Specialty) {
        this.Specialty = Specialty;
    }

    public void setEdition(String edition) {
        this.edition = edition;
    }

    public void setBorrowed(Boolean borrowed) {
        this.borrowed = borrowed;
    }

    public String getTitle() {
        return title;
    }

    public String getBook() {
        return book;
    }

    public String getAuthor() {
        return author;
    }

    public String getSpecialty() {
        return Specialty;
    }

    public String getEdition() {
        return edition;
    }

    public Boolean isBorrowed() {
        return borrowed;
    }

    @Override
    public String toString() {
        return "Book{" + "title=" + title + ", book=" + book + ", author=" + author + ", Specialty=" + Specialty + ", edition=" + edition + ", borrowed=" + borrowed + '}';
    }

    
}

رابعا Authorclass

package author;
import java.util.Date;
import java.util.Vector;
/**
 *
 * @author hams4242
 */
public class Author {

String name;
Date birth;
char sex;
Vector<Author> ListOfBook;

    public void setName(String name) {
        this.name = name;
    }

    public void setBirth(Date birth) {
        this.birth = birth;
    }

    public void setSex(char sex) {
        this.sex = sex;
    }

    public void setListOfBook(Vector<Author> ListOfBook) {
        this.ListOfBook = ListOfBook;
    }

    public String getName() {
        return name;
    }

    public Date getBirth() {
        return birth;
    }

    public char getSex() {
        return sex;
    }

    public Vector<Author> getListOfBook() {
        return ListOfBook;
    }

    @Override
    public String toString() {
        return "Author{" + "name=" + name + ", birth=" + birth + ", sex=" + sex + ", ListOfBook=" + ListOfBook + '}';
    }

    
}

كمان ماعرفت للميودPrintList: to print the author’s  book

والكلاس الاخير Borrwo interface 

ماعرفته اضافه للمين
