import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.Label;

public class FXMLDocumentController implements Initializable {@FXML private Label lblMensagem; private Button btnClick;
@FXML private void butaoClique(ActionEvent event) { lblMensagem.setText(“Olá Mundo!”); }
<a class="mention" href="/u/override">@Override</a> public void initialize(URL url, ResourceBundle rb) { // TODO }
}`
