I've just fix the problem! I've changed the code in this way:

-------------------------------------------------------
@Override
public boolean equals(Object o) {
if (o==this)
return true;
if (o instanceof Book) {
if (this.isbn.compareTo(((Book) o).getIsbn()) == 0)
                                 return true;
                       else return false;
             }
             return false;
          }
-------------------------------------------------------

The problem was the comparison between string! Now I use the compareTo() method and everything correctly works.

Thank you for your time Piotr!
