Question

in java

Assignment 2 is the first in a multipart series of assignments. The overall topic of the assignments will be the design and implementation of a system for keeping track of the holdings of a library This first assignment focuses on the development of a custom class to represent a book that belongs to the library. The class should be named "Book" and be based on the corresponding real-world concept of a book, and be able to represent the characteristics of a book that would be useful in a system designed to manage library holdings. In particular, your custom class should represent and track the following book characteristics: title (a String), author (a String), number of pages (an integer), and status (boolean). The status attribute should represent whether a book is currently checked out (a status value of "true") or not checked out (a status value of "false") In your custom class, include a constructor that can be used to initialize book objects as they are created. It should accept 3 parameters: a book title, a book author, and the number of pages in the book. Each of the values specified for the parameters should be used in the constructor to initialize the corresponding field of a new book object. The initial value of the status field for the book should be set to “false" to indicate it is currently not checked out.

Answer 1

Program

public class Book

{

                String title;

                String author;    //creating’s objects of the doss

                int numberOfPages;

                boolean status;

                public void Book (String title,String author,int numberOtPages){

                                this.title=title;

                                this.author=author;        //constructor to intiatize

                                this.,AmberOWages=nunberOfPages;

                }

                public void setTitle(String title){

                                this.title=title;

                }

                public void getTitle(){

                                return title;

                }

                public void setAuthor(String author){

                                this.author=author;        //differnt methods

                }

                public void getAuthor(){

                                return author;

                }

                public void setPages(int pages){

                                this.NumberOfPages=numberOfPages;

                }

                public void getPages(){

                                return numberOtPages;

                }

                public void setStatus(boolean status){

                                this.status=status;

                }

                public void setStatus(boolean status){

                                this.status=status;

                }

                public void getStatus(){

                                return status;

                }

public String toString(){

                System.out.println(" ' "A-title+","vauthor+","*ForberOfPages,","+status+" ' " ;

                }

                }

class MyBooks{

                public static void main(String []args){

                                Book Bookl = new Book("java programmng","Ronald pierce",475);

                                Book Boob_ = new Book("javaprecisely","peter sestoft",199);

                                Book Book3 = new Book("python programming for beginners","Bill ullman", 8);

                System.out.println("The original values of book objects are");

                Book1.toString();

                Book2.toString();

                Book3.toString();

                Book2.setPages(124);

                Book1.setTitle("Introduction to java programming");

                Book3.setAuthor("richard ullman");

                System.out.println("The original values of book objects are");

                Book1.toString();

                Book2.toString();

                Book3.toString();

                }

                }
