can you specify "an error occurs" – pL4Gu33 Mar 14 '21 at 20:26
Please read https://stackoverflow.com/help/asking first; eg. it would help when you'd not only complain but provide an actual **error message**; when it reads `NullPointerException`, my guess was right. – Martin Zeitler Mar 14 '21 at 20:44
