我正在使用此方法使用JavaFx应用程序创建一个Barchart startApplication（String chartPath，......）来自 Barchart.java ，我将在其中启动javafx应用程序
在那个方法中我也在做其他一些事情但是如果我想再次使用这个方法就像程序 TestBarchart.java 我不能使用因为应用程序已经已经启动的例外即将到来。
我想使用Platform.runLater，但我不确定如何使用它。我知道这可能是重复的。但是Platform.runLater会在事件触发时运行但在我的情况下没有触发器我只想运行该方法。
请让我知道如何才能让它发挥作用。
提前致谢
