primaryStage.setTitle("Hello World!");

final Label labelFile = new Label();

Button btn = new Button();
btn.setText("Open FileChooser'");
btn.setOnAction(new EventHandler<ActionEvent>() {

@Override
public void handle(ActionEvent event) {
FileChooser fileChooser = new FileChooser();

//Open directory from existing directory
if(file != null){
File existDirectory = file.getParentFile();
fileChooser.setInitialDirectory(existDirectory);
}

//Set extension filter
FileChooser.ExtensionFilter extFilter = new FileChooser.ExtensionFilter("AVI files (*.avi)", "*.avi");
fileChooser.getExtensionFilters().add(extFilter);

//Show open file dialog
file = fileChooser.showOpenDialog(null);

labelFile.setText(file.getPath());
}
});

VBox vBox = new VBox();
vBox.getChildren().addAll(labelFile, btn);

StackPane root = new StackPane();
root.getChildren().add(vBox);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
