// There should be an method in LibraryBooks class for getting
// Book object reference in it, in other words getter for Book.
// In LibraryBook.java
public Book getBook() {
   return book;

// through the collection of LibraryBooks and get book reference
public Book[] getAllBooks() {
   // create new book array
   allBooks = new Book[bookCollection.length];

   // iterate through all the LibraryBook objects in collection
   // and get the actual Book object
   for (int i = 0; i < bookCollection.length; ++i) {
       allBooks[i] = bookCollection[i].getBook();
   }

   // return allBooks array
   return allBooks;
}
