JAVA QUESTION

You are to develop the class Book that has:

1. The following instance variables:

private String title;

private String author;

private int pages;

private String category;

private boolean read;

private double cost;

2. The following getter (accessor) methods (Use the following headings - you are to complete the body of the method as described in my comment)

//Returns the title of the instance of the class Book that called the method

public String getTitle()

//Returns the author of the instance of the class Book that called the method

public String getAuthor()

//Returns the number of pages of the instance of the class Book that

//called the method

public int getPages()

//Returns the category of the instance of the class Book that called the

//method

public String getCategory()

//Returns the value of read of the instance of the class Book that called

//the method

public boolean getRead()

//Returns the cost of the instance of the class Book that called the method

public double getCost()

3. The following setter (mutator) methods (Use the following headings - you are to complete the body of the method as described in my comment)

//Sets the title of the instance of the class Book that called the method //to the value passed to the method

public void setTitle(String titlePassed)

//Sets the author of the instance of the class Book that called the method

//to the value passed to the method

public void setAuthor(String authorPassed)

//Sets the number of pages of the instance of the class Book that called the

//method to the value passed to the method. If the value passed to the

//method is 0 or less ask the user to reenter the amount, trapping //the user (through a while loop) until the user enters a value > 0. // HINT: you will have to declare an instance of the class Scanner within //the method

public void setPages(int pagesPassed)

//Sets the cost of the instance of the class Book that called the

//method to the value passed to the method. If the value passed to the //method is < 0 asks the user to reenter the amount, trapping //the user (through a while loop) until the user enters a value >= 0. // HINT: you will have to declare an instance of the class Scanner within //the method

public void setCost(double costPassed)

//Sets the variable read of the instance of the class Book that called the

// method to the value passed to the method

public void setRead(boolean readPassed)

//Sets the variable category of the instance of the class Book that called

//the method to the value passed to the method. If the value passed is not //Biography, "Children's","Cooking", "Fantasy", "Fiction", or "Technical" //set the value of variable category to Invalid

public void setCategory(String categoryPassed)

Test program using this code:

import java.util.Scanner;

public class BookTest

{

public static void main(String[] args)

{

Scanner keyboard = new Scanner(System.in);

Book b1 = new Book();

Book b2 = new Book();

String userInputTitle, userInputAuthor, userInputCategory;

int userInputPages;

double userInputCost;

boolean userInputRead;

System.out.println("Please enter the title of the first book:");

userInputTitle = keyboard.nextLine();

b1.setTitle(userInputTitle);

System.out.println("Please enter the author of the first book:");

userInputAuthor = keyboard.nextLine();

b1.setAuthor(userInputAuthor);

System.out.println("Please enter the category of the first book:");

userInputCategory = keyboard.nextLine();

b1.setCategory(userInputCategory);

System.out.println("Please enter the number of pages in the first

book:");

userInputPages = keyboard.nextInt();

b1.setPages(userInputPages);

System.out.println("Please enter the cost of the first book:");

userInputCost = keyboard.nextDouble();

b1.setCost(userInputCost);

System.out.println("Please enter if the first book has been read, true or

false:");

userInputRead = keyboard.nextBoolean();

b1.setRead(userInputRead);

System.out.println("The first book informaton is:");

System.out.println(b1.getTitle());

System.out.println(b1.getAuthor());

System.out.println(b1.getCategory());

System.out.println(b1.getPages());

System.out.println(b1.getCost());

System.out.println(b1.getRead());

keyboard.nextLine();//flush the line

System.out.println("Please enter the title of the second book:");

userInputTitle = keyboard.nextLine();

b2.setTitle(userInputTitle);

System.out.println("Please enter the author of the second book:");

userInputAuthor = keyboard.nextLine();

b2.setAuthor(userInputAuthor);

System.out.println("Please enter the category of the second book:");

userInputCategory = keyboard.nextLine();

b2.setCategory(userInputCategory);

System.out.println("Please enter the number of pages in the second

book:");

userInputPages = keyboard.nextInt();

b2.setPages(userInputPages);

System.out.println("Please enter the cost of the second book:");

userInputCost = keyboard.nextDouble();

b2.setCost(userInputCost);

System.out.println("Please enter if the second book has been read, true

or false:");

userInputRead = keyboard.nextBoolean();

b2.setRead(userInputRead);

System.out.println("The second book informaton is:");

System.out.println(b2.getTitle());

System.out.println(b2.getAuthor());

System.out.println(b2.getCategory());

System.out.println(b2.getPages());

System.out.println(b2.getCost());

System.out.println(b2.getRead());
