public static void launchApplication(final Class<? extends Application> appClass, final String[] args)

This method is called by the Application.launch method. It must not be called more than once or an exception will be thrown. Note that it is always called on a thread other than the FX application thread, since that thread is only created at startup.

Parameters
appClass:Class<? extends Application>

application class

args:String[]

command line arguments

public static void launchApplication(final Class<? extends Application> appClass, final Class<? extends Preloader> preloaderClass, final String[] args)

This method is called by the standalone launcher. It must not be called more than once or an exception will be thrown. Note that it is always called on a thread other than the FX application thread, since that thread is only created at startup.

Parameters
appClass:Class<? extends Application>

application class

preloaderClass:Class<? extends Preloader>

preloader class, may be null

args:String[]

command line arguments

launchApplicationback to summary
public static void launchApplication(final String launchName, final String launchMode, final String[] args)

This method is called by the Java launcher. This allows us to be launched directly from the command line via "java -jar fxapp.jar", "java -cp path some.fx.App", or "java -m module/some.fx.App". The launchMode argument must be one of "LM_CLASS", "LM_JAR", or "LM_MODULE" or execution will abort with an error.

Parameters
launchName:String

The path to a jar file, the application class name to launch, or the module and optional class name to launch

launchMode:String

The method of launching the application, one of LM_JAR, LM_CLASS, or LM_MODULE

args:String[]

Application arguments from the command line
