У меня есть простая игра, которая в процессе. На данный момент все, что я хочу сделать, это нажать зеленую кнопку, и пятая и третья части поменялись местами. PaintComponent вызывается после выполнения перестановки в массиве, но JPanel не обновляется, чтобы показать эти изменения. Когда я запускаю свое приложение, я выбираю по 4 штуки для каждой стороны. Таким образом, внутренние зеленые и черные фигуры должны поменяться местами. Пожалуйста, помогите.
