HELLLLLP!! How do you create the following Login Screen in JavaFX?:

Login Screen

• Stimulus/Response Sequences

The employee opens the application for the first time.

The employee is prompted for username and password to log into the system.

The employee enters their existing account credentials.

The employee presses the Login button.

The system responds telling if the credentials are valid or not.

• Requirements

1: Render login screen.

2: Validate employee username / password against the database.

3: Check with the database to determine if an account with the entered username already exists.

4: Log the employee into the system. Display a message telling the first name, last name, and ID of the employee who just logged in.

5: An appropriate error message must be displayed if the database is inaccessible.
