Localdate.format, format is not applied

I have a DatePicker in my FXML and I need the Date to insert it into my SQL-Database. I want to format my Date but it doesn\'t work.

    LocalDate localDate          


        

Answer 1

I had to use a String converter for my Datepicker.

    public String changeformat(DatePicker date) {

    date.setConverter(new StringConverter() {
        String pattern = "MM.yyyy";
        DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern(pattern);

        {
            date.setPromptText(pattern.toLowerCase());
        }

        @Override
        public String toString(LocalDate date) {
            if (date != null) {
                return dateFormatter.format(date);
            } else {
                return "";
            }
        }

        @Override
        public LocalDate fromString(String string) {
            if (string != null && !string.isEmpty()) {
                return LocalDate.parse(string, dateFormatter);
            } else {
                return null;
            }
        }
    });
    return null;
}

It worked perfectly fine. I had to use a parameter since I'm currently using 5 Datepickers.
