This is java problem. I have writen the codes i am not sure what i do wrong, please fix it or add to make it works. I am not sure what did i do wrong and why it wont compile this is the direction:

-The Book class models information common to all books.

-The LibraryBook class is a Book, but library books also have a call number, and the call number allows books to be ordered on the shelves. (The ordering is given by a compareTo specified in the Comparable interface. In addition, because many library books can circulate (be checked out and returned), each library book has a circulation status (e.g., on shelf, checked out, permanently in reference collection).

-A ReferenceBook is a type of Library Book that is housed in a specified collection (e.g., a reference area in Tioga, or in the Snoqulamie Building), and reference books do not circulate.

-A CirculatingBook is a type of Library Book located on the shelves until it is checked out, and the book is placed back on the shelves when it is returned.

code of book

This class i miss one which is comparable i am not sure what to do. this is the code

I am not sure how to write field collection but this is my code:

This is the code: i think my implement is wrong.

and lastly this is my code for the driver because the class is wrong i am not sure what to write here.

driver file Library.java. The driver file is incomplete. Library() constructor addBook() method printLibrary() method findBook() method

these is the code just copy paste:

import java.util.ArrayList;

import java.util.Collections;

public class Library {

// Declare a List of LibraryBook

ArrayList bookList;

Library (ArrayList bookList) {

// TO DO: Instantiate bookList

this.bookList = booklist;

}

/** TO DO:

* adds the given book to the library

* @param book

*/

public void addBook (LibraryBook book) {

Book.setTitle(book);

}

/** TO DO:

* prints all books in the library

*/

public void printLibrary () {

System.out.print(Book.tostring());

}

/** TO DO:

* locates a book in the library

* @param book book being search in the library

* @return book object if book is found

* null otherwise

*/

public LibraryBook findBook (LibraryBook book) {

int index = Collections.binarySearch(bookList, book);

/* @return book object if book is found

* null otherwise

*/

}

/**

* sort books in the library by call number

*/

public void sortLibrary () {

Collections.sort(bookList);

else

book.checkout (patron, dueDate);

}

if (book == null)

ALL the code i have made but i make some error that i could not see or i dont know could you guys help me to fix it so i know what i do wrong, These are not homework. But these are preparation for the next class that i have to take. If i dont know what i did wrong I am scared of what will take next class. Thanks

Class Book The Book class models information common to all books. Any book has: Fields: an author .an ISBN or International Standard Book Number that provides a unique number used by publishers and book stores Constructors and methods: a null constructor a constructor using 3 parameters for an author, title, and ISBN number getters and setters toString should provide a string of the field data in a format suitable for printing Within a Book class and its subclasses, these fields might be used directly, but processing by other classes and objects should bedone via getters and setters-encapsulation!
