Answer 1

in your file .java use this

Application.setUserAgentStylesheet(getClass().getResource("application.css")
                .toExternalForm());

Answer 2

Have you initialized the scene object prior to setting style sheet?

scene = new Scene(myRootLayout, 600, 600); // for example

Answer 3

Assuming the file structure is something like this:
-root
--src
---resources
----double_slider.css
---package
----JavaFXFile.java

This is what worked for me:

scene.getStylesheets().add((new File("src/resources/double_slider.css")).toURI().toString());

Answer 4

In a maven project you must define path for resources in the file.pom in the javafx-plugin section: something like this:

<configuration>
    <mainClass>com.personale.ciaomondo.App</mainClass>
          <resources>          
            <resource>
              <directory>src/main/resources</directory>
            </resource>
          </resources>
</configuration>

Answer 5

Folder Structure

In the MedicalLibraryFx.java

scene.getStylesheets().add(getClass().getResource("/css/style.css").toString()); 

---

Folder structure when css is in the same directory as controller

scene.getStylesheets().add(getClass().getResource("style.css").toString());

Answer 6

put your yourname.css file directly under src directory.

scene.getStylesheets().add("yourname.css")
