JAVA It is required to develop an application called Library System to maintain information aboutbooks and members in a library.(1) Write a class called Book having the following data members:title (String), author1 (String), author2(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 forissuedTo - initialize issuedTo to null), set and get methods for all attributes, equals andtoString.NOTE: The ISBN is a unique 13 digit number assigned by the publisher. It is like barcode. Asthere can be multiple copies of a book in a library, the libraries assign a unique number, calledaccession number, to every book in the library to keep track of the books in the library.Assume that accession number starts from 1001.(2) Write a class called LibMember having the following data members:firstName (String), lastName (String), gender (char), cprNum (long), teleNum (String),bookslssued (array of type Book, size = 10) and numBookslssued (int).Include following public methods in the class:Default constructor (without any parameters), constructor with 5 parameters (except forbookslssued and numBookslssued – initialize nubBiikslssued to 0), set and get methods forall attributes, equals and toString.(3) Write a class called LibrarySystem having the following data members:%3DbooksList:list of books - LinkedList object, each element is of type Book,membersList:list of members – LinkedList object, each element is of type LibMember,booksListSize: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 linkedlists and initialize booksListSize and membersListSize to 0.(ii) addBook:is passed as parameter. If the object already exists in the list, then do not add the objectand return false, else return true after successfully adding the Book.(iii) deleteBook:passed as parameter. If the Book is issued to a member or the object is not found in thebooksList, then the Book cannot be deleted and the method returns false, else theinserts a new Bookobject at the end of the booksList. Object of type Bookdeletes a Book object from booksList. Accession number of the Book ismethod returns true, after successfully deleting the object.(iv) addMember: inserts a new LibMember object at the end of the membersList. Object oftype LibMember is passed as parameter. If the object already exists in the list, then do1not add the object and return false, else return true after successfully adding themember.(v) deleteMember: deletes a LibMember object from membersList. CPR number of theLibMember is passed as parameter. If any Book is issued to the member or the object isnot found in the membersList, then the member cannot be deleted and the methodreturns false, else the method returns true, after successfully deleting the object.(vi) searchBook: searches the booksList by accessionNum, passed as parameter. If the objectis found, it returns its location in the booksList, else returns -1.(vii) searchMember: searches the membersList by cprNum, passed as parameter. If theobject 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 CPRnumber of the member as the second parameter. The Book can be issued to a memberonly if:(a) The Book exists in the booksList,(c) The Book is not issued to any member,(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 bookslssued(b)The member exists in the membersList,array for the member, increment numBookslssuedby 1 for the member and also makeissuedTo 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 bereturned only if:(a) The Book exists in the Books list,If the Book can be returned, then delete it from bookslssued array for the member,decrement numBookslssued by one for the member and also make issuedTo instancevariable of the Book object to null and return true. If the Book cannot be returned, then(b) The Book is issued to a member.return false.(xiv) printBookslssued: accepts CPR number of a member as a pameter and prints details ofall the books issued to the member.(xv) isBooklssued: accepts accession number of the Book as parameter.Book object exists in the bookList and is issued to a member, else returns false.returns true if the(4) Write a class called LibraryMain having only main method to test all the functionalities ofclass LibrarySystem.Write main as a menu driven program using switch statement.NOTE: For booksList and membersList, use LinkedList built-in class of java. It is a doubly linkedlist with Listlterator.Write detailed comments for each class and method. Write commentsusing Javadoc.2
