Answer 1

first, you need to set src and resource folders for IntelliJ.

see the icon near the java(blue) and resources(yellow 4 lines) folder.

right-click on java folder and select sources root

and right-click on java folder and select resource root

after that create the same package in the java folder and resource folder.

for example: packages -> org.example

├─ src
   ├─ main
       ├─ java
       |  └─ com
       |      └─ example
       |           └─ A.class
       |
       └─ resources  
          └─ com
              └─ example
                    └─ fxml
                         └─ AFXML.fxml

in A.class you can use this.

Java

 FXMLLoader loader = new FXMLLoader(getClass().getResource("fxml/AFXML.fxml"));
 Parent root = loader.load();

Kotlin

 val loader = FXMLLoader(javaClass.getResource("fxml/AFXML.fxml"))
 val root = loader.load()

or

 val loader = FXMLLoader(A::class.java.getResource("fxml/AFXML.fxml"))
 val root = loader.load()
