Is there a method similar to getSelectedFile in JavaFX that returns a File? I have tried this code now trying to perfect the commented out //fileToSend[0]

@FXML
private void chooseButtonAction(ActionEvent event) throws IOException {

    FileChooser JFileChooser = new FileChooser();
    JFileChooser.setTitle("Choose a file to send");
    
    Stage stage = (Stage) anchorPane.getScene().getWindow();
    File file = JFileChooser.showOpenDialog(stage);

    if (file != null) {
        //fileToSend[0] = JFileChooser.getSelectedFile();
        fileName.setText("File Name "   file.getName());
    }

}
