Я хочу добавить несколько JPanels в один JPanel. Затем я хочу взять это JPanel и отобразить его на вкладке JTabbedPane. Я попытался сделать это несколько раз, но затмение не позволит мне запустить программу. Он не показывает никаких ошибок, но по какой-либо причине программа всегда запускается в режиме отладки. Это что-то не так с кодом? (Код немного длинный извините)Добавление JPanel в другой JPanel
