Я новичок относительно программирования на Java, но то, что я пытаюсь сделать, это получить некоторые данные с веб-сайта через HtmlUnit с помощью java, и мне это удалось успешно, но мне нужно представить эти данные в JTable, и это то, где я потерялся. У меня есть один класс входа, который является моим классом gui и Nova, где происходит фактическое извлечение данных.Данные ArrayList должны быть представлены в JTable
