JavaFX FileChooser: how to set file filters?

Question

I want to set file filters in a JavaFX FileChooser but I could not find a way to do it.

My code:

  FileChooser fc = new FileChooser();   fc.setTitle("My File Chooser");   File f = fc.showOpenDialog(primaryStage);   System.out.println(f);

You could do:

FileChooser.ExtensionFilter extFilter = new FileChooser.ExtensionFilter("TXT files (*.txt)", "*.txt"); chooser.getExtensionFilters().add(extFilter); 

Here is a simple example:

public class ExtensionFilterExample extends Application {      public static void main(String[] args) {         launch(args);     }      @Override     public void start(final Stage primaryStage) {         primaryStage.setTitle("Extension Filter Example");          final Label fileLabel = new Label();          Button btn = new Button("Open FileChooser");         btn.setOnAction(new EventHandler<ActionEvent>() {              @Override             public void handle(ActionEvent event) {                 FileChooser fileChooser = new FileChooser();                  // Set extension filter                 FileChooser.ExtensionFilter extFilter =                          new FileChooser.ExtensionFilter("TEXT files (*.txt)", "*.txt");                 fileChooser.getExtensionFilters().add(extFilter);                  // Show open file dialog                 File file = fileChooser.showOpenDialog(primaryStage);                 if (file != null) {                     fileLabel.setText(file.getPath());                 }             }         });          VBox vBox = new VBox(30);         vBox.getChildren().addAll(fileLabel, btn);         vBox.setAlignment(Pos.BASELINE_CENTER);          StackPane root = new StackPane();         root.getChildren().add(vBox);         primaryStage.setScene(new Scene(root, 300, 250));         primaryStage.show();     } }

Update for JavaFX plus multiple extensions filter:

FileChooser fc = new FileChooser();  FileChooser.ExtensionFilter fileExtensions =    new FileChooser.ExtensionFilter(     "Web pages", "*.tpl", "*.html", "*.htm");  fc.getExtensionFilters().add(fileExtensions);
