LocalTime from Date

Question

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         


        

Answer 1

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);
    }
}
