The *JavaFX* *Separator* component shows a visual divider between groups of components - e.g. between groups of controls inside a [JavaFX VBox][] or [JavaFX VBox][JavaFX VBox 1]. The JavaFX Separator is represented by the class `javafx.scene.control.Separator`. Here is a screenshot of a JavaFX application containing a VBox with a Label, a Separator and a Label:

### Full JavaFX Separator Example ###

Here is a full JavaFX `Separator` example to give you an idea about how using it looks in code

import javafx.application.Application;
    import javafx.geometry.Orientation;
    import javafx.scene.Scene;
    import javafx.scene.control.Label;
    import javafx.scene.control.Separator;
    import javafx.scene.layout.VBox;
    import javafx.stage.Stage;
    
    public class SeparatorExample extends Application {
    
      public static void main(String[] args) {
        launch(args);
      }
    
      public void start(Stage primaryStage) {
    
        Label label1 = new Label("Component 1");
        Label label2 = new Label("Component 2");
    
        Separator separator = 
            new Separator(Orientation.HORIZONTAL);
    
        VBox vBox = new VBox(label1, separator, label2);
        Scene scene = new Scene(vBox);
    
        primaryStage.setScene(scene);
        primaryStage.setTitle("JavaFX App");
    
        primaryStage.show();
      }
    }

Notice how the `Separator` is passed as second parameter to the `VBox` component, between the first and second `Label`.

### Separator Orientation ###

You can specify whether the JavaFX `Separator` is supposed to be vertical or horizontal. You do so by passing a parameter to the `Separator` constructor. Here are two examples that set the orientation of the `Separator` created to horizontal and vertical:

Separator separator = new Separator(Orientation.HORIZONTAL);
    Separator separator = new Separator(Orientation.VERTICAL);
