Create a window for javafx and start another program

In javafx, a JVM process can only have one Application class. This Application class can only call the launch () method once to start it.

What if we start a new window?

In javafx, the Stage class inherits a Window, so we only need to construct a Stage and display it.

Stage secondWindow = new Stage (); Scene scene = new Scene (root, 300,275); secondWIndow. setTitle ("secondWindow"); secondWindow. setScene (scene); secondWindow. show ();

If you need to start another javafx program, you can do this:

Platform. runLater (new Runnable () {public void run () {new anotherApp (). start (new Stage ());}
