How do you put the date in the right format at the last downloaded file?

[simrah]

At the end of the code, I return to the column of the table the date of the last entered file, but the format of the date is "The Aug 26 16:45:55 SAMT 2021." I want to make another conclusion to "dd.mm.yyyy," how is that possible? Here's the code:

@Override
public Component generateCell(T entity) {
    String dataLastAttachment = "";
    List<CardAttachment> attachments = entity.getAttachments();
if (CollectionUtils.isNotEmpty(attachments)) {
    CardAttachment attachment = attachments.get(attachments.size() - 1);
    dataLastAttachment = attachment.getCreateTs().toString();
}

return new Table.PlainTextCell(dataLastAttachment);

The date/times that return from the method createTsusing the appropriate format.

This can be done either SimpleDateFormatif createTs returning a copy of the class java.util.Date:

import java.text.*;
// ...

@Override

public Component generateCell(T entity) {

String dataLastAttachment = "";

List<CardAttachment> attachments = entity.getAttachments();
if (CollectionUtils.isNotEmpty(attachments)) {

    CardAttachment attachment = attachments.get(attachments.size() - 1);

    DateFormat sdf = new SimpleDateFormat("dd.MM.yyyy");

    dataLastAttachment = sdf.format(attachment.getCreateTs());
}

return new Table.PlainTextCell(dataLastAttachment);

}

If method createTs() returning the copy Instant / ZonedDateTime / LocalDateTime from Java Date/Time API, formatting should be used DateTimeFormatter with similar patternum (in the case of Instant You've got to have a clock belt.

import java.time.;

import java.time.format.;

// ...
if (CollectionUtils.isNotEmpty(attachments)) {
    // предполагается что список отсортирован по дате
    CardAttachment attachment = attachments.get(attachments.size() - 1);

    DateTimeFormatter formatter = DateTimeFormatter
        .ofPattern("dd.MM.uuuu")
        .withZone(ZoneId.systemDefault());

    dataLastAttachment = formatter.format(attachment.getCreateTs());
}
