public class BookReservation {
  private Date creationDate;
  private ReservationStatus status;
  private String bookItemBarcode;
  private String memberId;

  public static BookReservation fetchReservationDetails(String barcode); // why this method is static 
}

This class looks different from the one which is represanted in the class diagram. The method is taking barcode as parameter does it search this barcode in catalog?

Hi @Lavakush_Mani_Tiwari, each book and member card will have a unique barcode. The system will read barcodes from books and members’ library cards.
