Answer 1

The issue that JavaFX is no longer part of JDK 11. The following solution works using IntelliJ (haven't tried it with NetBeans):

1. Add JavaFX Global Library as a dependency:

   Settings -> Project Structure -> Module. In module go to the Dependencies tab, and click the add "+" sign -> Library -> Java-> choose JavaFX from the list and click Add Selected, then Apply settings.

2. Right click source file (src) in your JavaFX project, and create a new module-info.java file. Inside the file write the following code :

   module YourProjectName { 
       requires javafx.fxml;
       requires javafx.controls;
       requires javafx.graphics;
       opens sample;
   }
   

   These 2 steps will solve all your issues with JavaFX, I assure you.
