Convert from java.util.Date to java.sql.Date

I am writing a programm for creating schedules for a bunch of users.
Now I have a controller called AddTermineController which should allow the end-user to create a schedule for another user and also a database connection class for schedules.
When trying to save the schedule I am getting this error:

java.util.Date cannot be cast to java.sql.Date

This is out of the database class where I have created the statements:

public void addTermin(Termin terminXL) throws ParseException {
    try {
        PreparedStatement stat = con.prepareStatement(ADD_TERMIN);
        stat.setInt(1, terminXL.getUserID().getValue());
        stat.setString(2, terminXL.getUserNameT().getValue());
        stat.setString(3, terminXL.getKommentar().getValue());
        stat.setString(4, terminXL.getKategorie().getValue());
        //TODO von und bis in einen Datum umwandeln um es in die Datenbank einzuspeichern
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("YYYY-MM-DD");
        Date datumVon = (Date) simpleDateFormat.parse(terminXL.getVon().getValue());
        Date datumBis = (Date) simpleDateFormat.parse(terminXL.getBis().getValue());
        stat.setDate(5, datumVon);
        stat.setDate(6, datumBis);
        stat.setString(6, terminXL.getBis().getValue());
        stat.setString(7, terminXL.getReferat().getValue());
        stat.executeUpdate();
        log.info("Neuer Termin angelegt");
    } catch (SQLException e) {
        e.printStackTrace();
    }
}

This is the error code I am given:
