The programming language is Java. Post only the complete code please. All classes should be serializable and comparable. The driver is also required for this.

Implementing GUI and sorting methods to this is optional, but greatly appreciated.

You are not required to use GUI for this project. Your output can be on the screen . However at the end of each run you must store all your lists in an array and then into a file.

Problem: you are to create an app for CSUS library. A Library has different members such as students. Members should be able to search for a book by different criteria such as title, author, and subject. As soon as the book is found in the library, then the student will check out the book and this book will be added to the list of the books that the student has borrowed. When a student returns a book, then that book must be remove from his/her list. The information about items and students must be read from files.

Your program must have the input validation such that no user can enter wrong data. Use exception handling whenever possible. In the client class you must use methods. Everything needs to be done through a method call. You are free to add any functionality to your program and any creativity will be appreciated. Your program must read the data from a file. You need three different files for books, students and administrators.

.

Steps to complete your project: 1. There are 6 different classes and you need to implement all these classes and make sure that they work properly by writing client class. You must read the information for the students and books from files to populate the ArrayList for the class students and books.

2. In the main method you must provide the following functionalities Students should be able to do :

o Search by author //must write a method o Search by subject//must write a method o Search by topic//must write a method o Search by keyword//must write a method o After the item is selected, the item must be added to the student list of

checked out items if the item is available.

Admin people should be able to do the following.

o Search for items o Addanewitem o Delete a new item o Add a student

o Remove a student o Search for a student

When implementing the client class, you must use many different methods. Everything must be done through a method call. For example for searching a student in the array you must write a method. Codes without any methods will receive no credit.

Before logging out the application all the updated data must be stored in a file. When you run your program all the data must be loaded from the file back to the lists that you are suppose to create for your program.

Description: In this project you are going to develop a library application. Using this application students will be able to search for books, video CD, journals, and audio CD. Administrators will use this app to add or remove resources from the database in the library. Therefore the main page should have to different options

o Students (id number is required). If student is not found in the list of the students then n error message should be displayed

o Administrators (id number is required). If the id is not found an error message must be displayed

Students Students should be able to search the data base using different search criteria such as:

Title Subject

Keywords in the subject

Keywords in the title

Once the search criteria is declared by the user, then the list of all the available resources must appear on the screen. Once the user selects the desired item, then the status for the item must be changed to check out and the item must be added to the student account. A return date must be specified for the user. When a book is returned by a student, first your app must make sure that the book has been returned on time otherwise a penalty will be added to the user account. If the total penalty is more than 50 dollars on a student account, then a hold will be put on the user account and the student will no longer be able to check out any books.

All the information for the students and resources must be stored in a file therefore every time you log out the system all the info must be saved to a file. As soon as you log in all the info must be read from files and stored in appropriate collections. You must make all your classes serializable

Administrators: Administrators should be able

To add or remove items to/from the database

Add or remove students

Put a hold on a student account

Search through the students and send a notification to the students who have pass

due item

To implement this application we need the following classes 1. Item (holds information about a book, cd or journal)

Item

-String title -String subject -String author -String publisher -String yearPublished// must be validated -boolean status

-String type// validate type it can only be book, journal audio CD , Video CD

+Item(String t, string s, string a, string p, string y, boolean stat, string typ) +Item() +all the accessors +all the mutator

+toString(): String +equals(Item i): Boolean +contains(String s)// returns true if the string s is found in the title +compareTo(Item i): int //compare based on the title and author -Validatedate(string d): boolean

2. Person (holds info such as name, last name, ID, email, phone number)

Person

- String name

- String lastName

- String id //must validate the format

- String email //must be validate the format

- String phone//must validate the format

+ Person(String n, string l, string initialed, String em, string p) +person() +accessors, mutators +toString(): String

+equals(Person p): Boolean //based on the ID number

+compaerTo(Persom p): int -validateId(String id): boolean -validateemail(String email) : boolean -validate(String phone) : boolean

//based on the last name

3. Library (holds a collection of items)

Library

-ArrayList items

+Library() +getSize(): int +add(Item i): Boolean //returns false if the item already exists, need to use equals method from the item class

+remove(item i): boolean //returns false if the item is not in the list, need to use the equals method from the item class +searchTitle(String title): item //search the array based on the title, returns null if the object not found, need to use the equals method from the item class +searachSubject(String subject): item //search the item based on the subject, return null if the object is not found, need to use the equals method from the item class +searchkeyword(String key): Item // returns the item based on the keyword, the keyword could be in the subject or title of the item. Need to use the contains method from the item class

4. Student

Student

-person -ArrayList checkedout

+student(Person p) +accessors, mutators +equals(Students s) // use the equals method from the person class +addcheckedOut(Item i)// adds the checked out item to the list +toString(): String

5. Students

Students

-ArrayList

+Students() +add(Student s) +remove(Student) +serachStudent(String id): Boolean +toString(): String

6. Administrator

Administrator

-ArrayList

+Administrator() +add(Person p) +remove(Person p) +search(Person P) +toString(): String
