/**
* Tester for Book class
*/
public class BookRunner
{
public static void main(String[] args)
{
ArrayList<Book> inventory = new ArrayList<Book>();
inventory.add(new Book(\"Hamlet\", \"play\"));
inventory.add(new Book(\"Beekeeper\'s Apprentice\", \"mystery\"));
inventory.add(new Book(\"Big Java\", \"non-fiction\"));
inventory.add(new Book(\"Beekeeper\'s Apprentice\", \"mystery\"));
inventory.add(new Book(\"Bad Business\", \"mystery\"));
inventory.add(new Book(\"Violet the Pilot\",\"juvenile fiction\" ));

Collections.sort(inventory);
for (Book b: inventory)
{
System.out.printf(\"%-18s%s%n\",b.getGenre(), b.getTitle());
}

}
}

Book.java

public class Book implements Comparable<Book>{
