JavaFX two buttons label change

JavaFx User Interface Components: Exercise-2 with Solution

Write a JavaFX program with two buttons. When the first button is clicked, the label should display "Button-1 clicked." Similarly, clicking the second button should change the label to "Button-2 clicked".

Sample Solution:

JavaFx Code:


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

public class Main extends Application {

    public static void main(String[] args) {

    public void start(Stage primaryStage) {
        primaryStage.setTitle("Two Buttons App");

        // Create a label with the initial text.
        Label label = new Label("No button clicked.");

        // Create the first button.
        Button button1 = new Button("Button 1");

        // Create the second button.
        Button button2 = new Button("Button 2");

        // Set actions for the buttons to change the label text.
        button1.setOnAction(event -> {
            label.setText("Button-1 clicked.");

        button2.setOnAction(event -> {
            label.setText("Button-2 clicked.");

        // Create a layout (VBox) to arrange the label and buttons.
        VBox root = new VBox(10);
        root.getChildren().addAll(label, button1, button2);

        // Create the scene and set it in the stage.
        Scene scene = new Scene(root, 300, 200);

        // Show the window.


In the exercise above, we create a label with the initial text "No button clicked" and two buttons labeled "Button 1" and "Button 2." When we click the first button, the label displays "Button-1 clicked," and when we click the second button, the label changes to "Button-2 clicked." The label, buttons, and the layout are organized using a "VBox".
