How can I anchor text at the center?

ShowText.java

package je3.thread;

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.text.Text;
import javafx.stage.Stage;

/**
 * Text seemed to be anchored at the bottom left corner.
 * See screenshot here: http://i60.tinypic.com/2mnnmrn.jpg

public class ShowText extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        Pane pane = new Pane();
        pane.setPadding(new Insets(0, 0, 0, 0));
        Text text1 = new Text(20, 20, "Programming fun");
//        text1.setFont(Font.font("Courier", BOLD, FontPosture.ITALIC, 15));
        Text text2 = new Text(30, 30, "Programming fun");
        Text text3 = new Text(40, 40, "Programming fun");
//        text3.setFill(Color.RED);
//        text3.setUnderline(true);
        pane.getChildren().addAll(text1, text2,text3);
        Scene scene = new Scene(pane);
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}
