Чат с GUI - Java

Узнай цену своей работы

Формулировка задачи:

Доброго времени суток. У меня такая проблема. У меня есть готовый код для сетевого чата на Java, сделанный по видео уроку. Проблема в том, что в данном уроке код был сделан так, чтобы можно было его презентовать на одном компьютере (2 пользователя на одном компьютере). Мне же для курсовой работы требуется продемонстрировать работу данной программы на 2 компьютерах. Заранее огромное спасибо. Вот сам код. Main.java 
package LANChatv2;

    /**
     * @param args the command line arguments

        // TODO code application logic here
    }
