How To Make A Login Page In Javafx

How To Articles

Creating a login page in JavaFX is a great way to enhance the user experience of your application. In this article, I will guide you through the process step by step and provide personal insights along the way. So, let’s dive into the world of JavaFX and learn how to create a login page!

Setting up the Project

First, let’s set up our JavaFX project. Open your favorite IDE and create a new JavaFX project. Make sure you have the necessary dependencies and libraries added to your project classpath.

If you are using IntelliJ IDEA, you can do this by going to File > New > Project and selecting “JavaFX” as the project type. For Eclipse, you can use the e(fx)clipse plugin to create a JavaFX project. Once your project is set up, we can move on to creating the login page.

Designing the Login Page

Designing the login page involves creating a JavaFX UI layout that includes input fields for the username and password, as well as buttons for logging in and signing up. You can use FXML or Java code to create your UI layout.

In this article, I will demonstrate how to create the UI layout using FXML. First, create a new FXML file called “login.fxml” and add the following code:

<?xml version="1.0" encoding="UTF-8"?>
<BorderPane xmlns="" xmlns:fx="" fx:controller="com.example.LoginController">
<VBox spacing="10" alignment="center">
<Label text="Login" styleClass="title" />
<TextField fx:id="usernameField" promptText="Username" />
<PasswordField fx:id="passwordField" promptText="Password" />
<Button text="Login" onAction="#login" />
<Button text="Sign Up" onAction="#signup" />

The above code defines a simple login page layout with a centered VBox containing a title label, username and password input fields, and login and sign up buttons. We have also defined the controller class as “LoginController” using the fx:controller attribute.

Implementing the Controller

Now, let’s create the LoginController class that will provide the functionality for our login page. In the controller, we will handle user input, validate the login credentials, and navigate to the main application page upon successful login.

Create a new Java class called “LoginController” and add the following code:

import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;

public class LoginController {
private TextField usernameField;

private PasswordField passwordField;

private void login() {
String username = usernameField.getText();
String password = passwordField.getText();

// TODO: Validate login credentials and navigate to main application page

private void signup() {
// TODO: Implement sign up functionality

The above code defines the LoginController class with two instance variables representing the username and password input fields. We have also defined two methods, “login” and “signup”, which will be invoked when the respective buttons are clicked.

Adding Functionality

Now that we have set up the UI layout and controller, it’s time to add the actual functionality to our login page. In the “login” method, you can perform the necessary validation of the login credentials and navigate to the main application page if the credentials are correct.

Similarly, in the “signup” method, you can implement the functionality for user registration. This may involve storing the user’s information in a database or performing any other necessary tasks related to user sign up.

Remember to update the TODO comments in the controller code with your own implementation. You can also add additional features and personal touches to the login page, such as adding a “Forgot Password” link or customizing the UI design.


Creating a login page in JavaFX can greatly enhance the security and usability of your application. By following the steps outlined in this article, you should now have a good understanding of how to design and implement a login page in JavaFX. Remember to personalize your login page and add your own unique features to make it stand out!
