public class ZonedDateTimeExample {
 
    public static void main(String[] args) {
         getInstances();
    }

    private static void getInstances() {
       // Current date time with zone
        ZonedDateTime dateTime = ZonedDateTime.now();
        System.out.println(dateTime);

       // Get LocalDate
        LocalDate localDate = dateTime.toLocalDate();
        System.out.println(localDate);
    }
}
