import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class ButtonExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        Button button = new Button("Click me");
        button.setOnAction(event -> {
            button.setText("stage1");
            button.setVisible(false);
        });

        StackPane root = new StackPane();
        root.getChildren().add(button);

        Scene scene = new Scene(root, 200, 200);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
