问题描述

我们有什么方法可以检查我们的javaFx应用程序是否已经运行。如果是，则显示现有的应用程序实例，否则启动一个新实例。

Is there any way that we can check if our javaFx application is already running. If yes then show the existing instance of application otherwise launch a new instance.

推荐答案

我确信可能有更好的解决方案在那里，但是当我遇到这个问题时，我刚刚制作了一个布尔值，一旦运行了start方法就会改变它，默认为false。

Well I am sure there is probably a better solution out there, but when I encountered the issue I just made a boolean that would be changed once the start method was ran having it false as default.
