我有MVC的两面。在模型方面，是我拥有整个战舰计划的主要课程的地方。它实例化视图/控制器方面的东西，包括3个不同的窗口（扩展应用程序的类）：一个PreBoard，它获取两个玩家的名字，然后每个玩家一个（P1Board，P2Board）。在所有这三个单独的类中，它们扩展了Application，并且都有一个start（Stage primaryStage）方法。
自从我在过去48小时内阅读有关javaFX线程的文章以来，我仍然几乎不了解javaFX应用程序线程的起始位置。 javaFX Application线程是否在第一次调用Application.launch（）时启动，即使你有3个单独的类来扩展Application并拥有自己的启动方法？
我最初的意图是有一个窗口让玩家可以输入他们的名字，然后是一个单独的窗口和他们自己的棋盘，我已经失败了，因为我越来越多的例外，整个程序运行的时间越长。
所以问题是，javaFX应用程序线程在哪里开始？
主要类，在模型方面
