yes button can we can change text of a button and then that button can repeat action of the first button you can use the bellow code to do that.

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.stage.Stage;

public class Main extends Application {
  public static void main(String[] args) {
    Application.launch(args);
  }

  @Override

    primaryStage.setTitle("Hello World!");

    lbl.setLayoutX(70);
    lbl.setLayoutY(150);

    btn.setLayoutX(100);
    btn.setLayoutY(100);
    btn.setText("Hello, World!");

    btn.setOnAction(new EventHandler<ActionEvent>() {

      @Override
      public void handle(ActionEvent event) {
        lbl.setText("Hello, World.");
      }
    });

    Group root = new Group();
