I'm trying to convert a Date
instance to a LocalTime
instance.
// Create the Date
Date date = format.parse("2011-02-18 05:00:00.0");
// Convert to Calendar
Calendar cal = Calendar.getInstance();
cal.setTime(date);
// Convert Calendar to LocalTime
Instant instant = Instant.ofEpochMilli(cal.getTimeInMillis());
LocalTime convert = LocalDateTime.ofInstant(instant, ZoneId.systemDefault()).toLocalTime();
I don't get a compiler error but the LocalTime
instance values are wrong.
I think it does not work because Date
stores time in fasttime
instead of cdate
.
I'm using JDK version 1.8.
Your input is effectively a LocalDateTime
. It would be much simpler to simply parse that to a LocalDateTime
and then get the LocalTime
from that. No time zones to worry about, no somewhat-legacy classes (avoid Date
and Calendar
where possible...)
import java.time.*;
import java.time.format.*;
import java.util.*;
public class Test {
public static void main(String[] args) {
DateTimeFormatter formatter =
DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.S", Locale.US);
String text = "2011-02-18 05:00:00.0";
LocalDateTime localDateTime = LocalDateTime.parse(text, formatter);
LocalTime localTime = localDateTime.toLocalTime();
System.out.println(localTime);
}
}
