A$.$ Write a class called Book having the following data members:

title $($String$),$ author$1($String$),$ author$2($String$),$ publisher $($String$),$ yearPublication $($int$),$

isbn $($String$),$ accessionNum $($long$),$ issuedTo $($LibMember$).$

Include following public methods in the class:

Default constructor $($without any parameters$),$ constructor with $6$ parameters $($except for

issuedTo $$ initialize issuedTo to null$),$ set and get methods for all attributes, equals and

toString.

NOTE: The ISBN is a unique $13$ digit number assigned by the publisher. It is like barcode. As

there can be multiple copies of a book in a library, the libraries assign a unique number, called

accession number, to every book in the library to keep track of the books in the library.

Assume that accession number starts from $1001.$

B$.$ Write a class called LibMember having the following data members:

firstName $($String$),$ lastName $($String$),$ gender $($char$),$ cprNum $($long$),$ teleNum $($String$),$

booksIssued $($array of type Book, size $=10)$ and numBooksIssued $($int$).$

Include following public methods in the class:

Default constructor $($without any parameters$),$ constructor with $5$ parameters $($except for

booksIssued and numBooksIssued $$ initialize nubBiiksIssued to $0),$ set and get methods for

all attributes, equals and toString.

C$.$ Write a class called LibrarySystem having the following data members:

booksList:

list of books $$ LinkedList object, each element is of type Book,

membersList:

booksListSize:

list of members $$ LinkedList object, each element is of type LibMember,

actual number of objects of type Book in booksList,

membersListSize: actual number of objects of type LibMember in membersList.

Include following methods in this class:

$($i$)$ Constructor without any parameters. Create booksList and membersList as empty linked

lists and initialize booksListSize and membersListSize to $0.$

$($ii$)$ addBook:

inserts a new Bookobject at the end of the booksList. Object of type Book

is passed as parameter. If the object already exists in the list, then do not add the object

and return false, else return true after successfully adding the Book.

$($iii$)$ deleteBook: deletes a Book object from booksList. Accession number of the Book is

passed as parameter. If the Book is issued to a member or the object is not found in the

$1$

booksList, then the Book cannot be deleted and the method returns false, else the

method returns true, after successfully deleting the object.

$($iv$)$ addMember: inserts a new LibMember object at the end of the membersList. Object of

type LibMember is passed as parameter. If the object already exists in the list, then do

not add the object and return false, else return true after successfully adding the

member.

$($v$)$ deleteMember: deletes a LibMember object from membersList. CPR number of the

LibMember is passed as parameter. If any Book is issued to the member or the object is

not found in the membersList, then the member cannot be deleted and the method

returns false, else the method returns true, after successfully deleting the object.

$($vi$)$ searchBook: searches the booksList by accessionNum, passed as parameter. If the object

is found, it returns its location in the booksList, else returns $-1.$

$($vii$)$ searchMember: searches the membersList by cprNum, passed as parameter. If the

object is found, it returns its location in the membersList, else returns $-1.$

$($viii$)$ isEmptyBooksList: returns true if the booksList is empty, else returns false.

$($ix$)$ isEmptyMembersList: returns true if the membersList is empty, else returns false.

$($x$)$ sizeBooksList: returns instance variable booksListSize.

$($xi$)$ sizeMembersList: returns instance variable membersListSize.

$($xii$)$ issueBook: accepts accession number of a Book as the first parameter and the CPR

number of the member as the second parameter. The Book can be issued to a member

only if:

$($a$)$ The Book exists in the booksList,

$($c$)$ The Book is not issued to any member,

$($b$)$The member exists in the membersList,

$($d$)$ The member has less than $10$ books issued to him$/$her$.$

If the book can be issued to a member, then add the Book object in the booksIssued

array for the member, increment numBooksIssuedby $1$ for the member and also make

issuedTo instance variable of the Book object reference to the member and return true.

If the Book cannot be issued then return false.

Note that there will be cross referencing between the book and the member.

$($xiii$)$ returnBook: accepts accession number of a Book as the parameter. The Book can be

returned only if:

$($a$)$ The Book exists in the Books list,

$($b$)$ The Book is issued to a member.

If the Book can be returned, then delete it from booksIssued array for the member,

decrement numBooksIssued by one fo
