It throws nosuchelementexception

[scenic magnet]

This is my code
The error falls around this part of the code:
public void Crearusuario() {
String user = "";
String password = "";
Scanner scanner = new Scanner(System.in);
System.out.print("Escribe un nombre de usuario: ");
user = scanner.nextLine();
System.out.print("Escribe una clave: ");
password = scanner.nextLine();

    String hashedpassword = Integer.toString(password.hashCode());
    userdata.put(user, hashedpassword);
    datab.put(user, datos);
    // scanner.close();
}

The output is
Escribe un nombre de usuario: Exception in thread "main" java.util.NoSuchElementException: No line found
at java.base/java.util.Scanner.nextLine(Scanner.java:1651)
at Terminal.Crearusuario(Terminal.java:40)
at Terminal.main(Terminal.java:133)

Are you requesting user input from multiple methods?

Are you calling the method multiple times?

Once you call close(), you cannot use System.in again unless you restart the program

Create only one Scanner object and create it outside of any methods...

And you should be able to avoid this error.
