title: Make JavaFX application thread wait for another Thread to finish
body: <p>I am calling a method inside my UI thread. Inside this method a new thread is created. I need the UI thread to wait until this new thread is finished because I need the results of this thread to continue the method in the UI thread. But I don´t want to have UI frozen while its waiting. Is there some way to make the UI thread wait without busy waiting?.</p>
