Привет всем Я пытаюсь запрограммировать клиентскую версию Tic Tac Toe, и у меня возникают проблемы. Я действительно потерялся и потратил 8 часов, пытаясь понять, что случилось. В настоящее время я пытаюсь добавить сообщение в JTextArea в свой пользовательский интерфейс. Но он не хочет ничего добавлять в текстовую область. Любая помощь будет принята с благодарностью.Не удается добавить JTextArea
