Теперь проблема, с которой я сталкиваюсь, заключается в том, что мне не нужен раздел «Возврат деталей» из счета. Я просто хочу добавить раздел с заголовком компании, а не раздел с информацией и клиентом, а затем продать только детали и общее количество.

Я пишу свой код, в который я внес изменения в соответствии с моими требованиями, но я не могу сократить раздел сведений о возврате и раздел подписи. ниже мой код:

          String company = ""
            + "V.K Autos Larkana\n"
            + "Near Rehmaniya Masjid Larkana\n"

и я хочу уменьшить ее ширину, текущая ширина платы равна 48, но когда я изменяю ее значение на 40, она также показывает мне ошибку :( пожалуйста, любой может помочь мне через это.
