public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    //  prompt for the user's name
    System.out.print("Enter your name: ");

    // get their input as a String
    String username = scanner.next();

    System.out.println(username);

    SpringApplication.run(Application.class, args);
}
