This Modern Login System is a Java Swing-based graphical user interface (GUI) application that provides a simple and user-friendly login system. Users can easily log in with their predefined usernames and passwords. This project aims to offer a modern and sleek login experience for users while maintaining simplicity and ease of use.

The ModernLoginSystem consists of several Java classes:

• Main.java: The main class to start the application. It initializes the login page.
• IDandPasswords.java: Stores predefined usernames and passwords in a HashMap.
• LoginPage.java: Creates the login page with text fields for username and password, along with login and reset buttons. It validates user input and displays appropriate messages.
• WelcomePage.java: Displays a welcome message upon successful login and provides a clickable link to redirect users to a custom domain.

To add new ID and passwords, users can directly modify the IDandPasswords.java file. Simply add new entries to the logininfo HashMap with the desired username-password pairs.

public IDandPasswords() {
    logininfo.put("username1", "password1");
    logininfo.put("username2", "password2");
    // Add more username-password pairs as needed
}

• User-Friendly Interface: The application provides a modern and sleek login interface with text fields and buttons for easy interaction.
• Validation: It validates user input for both username and password fields and displays appropriate messages for invalid input.
• Reset Functionality: Users can reset the input fields with the click of a button for convenience.
• Welcome Message: Upon successful login, users are greeted with a welcome message and provided with a clickable link to navigate to a custom domain.
