Question

Book information (overriding member methods) Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a printlnfomethod that overrides the Book class printinfo() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes. Ex. If the input is The Hobbit J. R. R. Tolkien George Allen & Unwin 21 September 1937 The Illustrated Encyclopedia of the Universe James W. Guthrie Watson-Guptill 2001 2nd 1 the output is: Book Information: Book Title: The Hobbit Author: J. R. R. Tolkien Publisher: George Allen & Unwin Publication Date: 21 September 1937 Book Information: Book Title: The Illustrated Encyclopedia of the Universe Author: James W. Guthrie Publisher: Watson-Guptill Publication Date: 2001 Edition: 2nd Number of Volumes: 1 Note: Indentations use 3 spaces 261744 1399928 LAB ACTIVITY 11.17.1: LAB: Book information (overriding member methods) 0/10 File is marked as read only Current file: BookInformation.java 1 import java.util.Scanner; 3 public class BookInformation 2

Answer 1

Answer:

Explanation:

The Book class and BookInformation class was not provided but was found online. After analyzing both of these classes I have created the following code that grabs and overrides the printInfo() method in order to add and print the edition and number of volumes as well

public class Encyclopedia extends Book {

   String edition;

   int numVolumes;

   public String getEdition() {

       return edition;

   }

   public void setEdition(String edition) {

       this.edition = edition;

   }

   public int getNumVolumes() {

       return numVolumes;

   }

   public void setNumVolumes(int numVolumes) {

       this.numVolumes = numVolumes;

   }

   public void printInfo() {

       System.out.println("Book Information: ");

       System.out.println(" Book Title: " + super.title);

       System.out.println(" Author: " + author);

       System.out.println(" Publisher: " + publisher);

       System.out.println(" Publication Date: " + publicationDate);

       System.out.println(" Edition: " + getEdition());

       System.out.println(" Number of Volumes: " + getNumVolumes());

   }

}
