Write a program that displays five texts vertically,
as shown in Figure 14.44a. Set a random color and opacity for each text
and set the font of each text to Times Roman, bold, italic, and 22 pixels.

import javafx.application.Application;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.GridPane;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.stage.Stage;

public class Exercise_04 extends Application {

    public void start(Stage primaryStage) {

        GridPane pane = new GridPane();
        Label[] labels = new Label[5];
        for (int i = 0; i < labels.length; i++) {
            labels[i] = new Label("Java");
            labels[i].setFont(Font.font("Times New Roman", FontWeight.BOLD, FontPosture.ITALIC, 22));

            pane.add(labels[i], i, 0);

        Scene scene = new Scene(pane, 250, 100);
        primaryStage.setTitle("Java text");

    private Color getRandomColor() {
        return new Color(Math.random(), Math.random(), Math.random(), Math.random());
    public static void main(String[] args) {
