How to add Date And Time on the same Input Date?

Question

if add date then time the inputDate modify by default in 01/01/1970 08:00:00 During the commit

for Example:
DispDeb = 02/08/2019 and DispFin 02/08/2019 but time in DispDeb 08:00 and in DispFin 12:00

My Problem

if add date in DispDeb 02/08/2019 and Time in inputText 08:00 change my date in DispDeb and in DispFin and in my commit add into the table DispDeb 01/01/1970 08:00 and DispFin 01/01/1970 12:00 Error javax.DateTimeConverter converter

Im not really sure what you're trying to do from the question but you can simplify converting

DispDeb = 02/08/2019 and  DispDeb 08:00

Like this:

DateTimeFormatter DATE_TIME_FORMATTER = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm")
                .withZone(ZoneId.systemDefault());

String date = "2019/12/19";
String time = "12:00";

String dateTime = date + " " + time;

LocalDateTime localDateTime = LocalDateTime.parse(dateTime, DATE_TIME_FORMATTER);
System.out.println(localDateTime);

Timestamp timestamp = Timestamp.valueOf(localDateTime);
System.out.println(timestamp);

hope that helps
