Java String to DateTime
You don't need a DateTime
object. java.util.Date
stores the time too.
int hours = start.getHours(); //returns the hours
int minutes = start.getMinutes(); //returns the minutes
int seconds = start.getSeconds(); //returns the seconds
As R.J says, these methods are deprecated, so you can use the java.util.Calendar
class:
Calendar calendar = Calendar.getInstance();
calendar.setTime(sdf.parse("2013-09-18T20:40:00+0000"));
int hour = calendar.get(Calendar.HOUR); //returns the hour
int minute = calendar.get(Calendar.MINUTE); //returns the minute
int second = calendar.get(Calendar.SECOND); //returns the second
Note: on my end, sdf.parse("2013-09-18T20:40:00+0000")
fires a
java.text.ParseException: Unparseable date: "2013-09-18T20:40:00+0000"
at java.text.DateFormat.parse(DateFormat.java:357)
at MainClass.main(MainClass.java:16)
You can create Joda DateTime object from the Java Date object, since Java does not have a DateTime
class.
DateTime dt = new DateTime(start.getTime());
Though the Date
class of Java holds the time information as well(that's what you need in the first place), I suggest you to use a Calendar
instead of the Date
class of Java.
Calendar myCal = new GregorianCalendar();
myCal.setTime(date);
Have a look at the Calendar docs for more info on how you can use it more effectively.
Things have changed and now even Java (Java 8 to be precise), has a LocalDateTime and ZonedDateTime class. For conversions, you can have a look at this SO answer(posting an excerpt from there).
Given: Date date = [some date]
(1) LocalDateTime << Instant<< Date
Instant instant = Instant.ofEpochMilli(date.getTime());
LocalDateTime ldt = LocalDateTime.ofInstant(instant, ZoneOffset.UTC);
(2) Date << Instant << LocalDateTime
Instant instant = ldt.toInstant(ZoneOffset.UTC);
Date date = Date.from(instant);
You can use DateTimeFormatter
DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
DateTime time = format.parseDateTime("2013-09-18T20:40:00+0000");
