Problem Description:

We continue the theme of a book catalog. In the previous homework you were asked to write Book, CatalogItem and Catalog classes, and to test the Catalog class in the Driver class. In your tests, you had to hard-code various book values to be used in the catalog.

In this homework, we’ll add a mechanism to load book values into your Catalog dynamically: via a csv file and by entering book values through the terminal.

A copy of the Catalog, CatalogItem and Book classes from the previous homework is posted below. Feel free to use them as a starting point for this assignment.

Catalog.java:

import java.util.ArrayList;
public class Catalog
{
 private ArrayList

CatalogItem.java:

public class CatalogItem
{
 private Book book;
 private String uniqueId;
 private boolean available;
 public CatalogItem(Book book, String id, boolean availability)
 {
 this.book = book;
 this.uniqueId = id;
 this.available = availability;
 }
 public Book getBook()
 {
 return this.book;
 }
 public String getId()
 {
 return this.uniqueId;
 }
 public boolean isAvailable()
 {
 return this.available;
 }
 public void setAvailable()
 {
 this.available = true;
 }
 public void setUnavailable()
 {
 this.available = false;
 }
}

Book.java:

public class Book
{
 private String title;
 private String firstName;
 private String lastName;
 public Book(String title, String firstName, String lastName)
 {
 this.title = title;
 this.firstName = firstName;
 this.lastName = lastName;
 }
 public String getTitle()
 {
 return this.title;
 }
 public String getAuthorFirstName()
 {
 return this.firstName;
 }
 public String getAuthorLastName()
 {
 return this.lastName;
 }
 public String toString()
 {
 return new String(this.title+", "+this.firstName+", "+this.lastName);
 }
}

We want to provide the user with two different ways to load books:

  • through a csv file
  • by interactively entering book values in the terminal
