joda time unexpected format

I'm trying to use Joda-Time library to convert a String date and time to Date but the result I get is not the expected.
From the server I get:
08/11/2017 12:30
10/11/2017 12:30
Joda converts it to:
2017-01-08T12:30:00.000+02:00
2017-01-10T12:30:00.000+02:00
DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/mm/yyyy HH:mm:ss");
// add two :00 at the end for the seconds
startDate = startDate +":00";
DateTime start = formatter.parseDateTime(startDate);
System.out.println(start.toString());
endDate= endDate + ":00";
DateTime end = formatter.parseDateTime(endDate);

That's because you're using mm for the month, but the correct pattern is uppercase MM. Check the documentation for more details.
One more thing. If your input doesn't have the seconds (:00), you don't need to append it in the end of the input strings. You can simply create a pattern without it:
// "MM" for month, and don't use "ss" for seconds if input doesn't have it
DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy HH:mm");
// parse input (without ":00" for the seconds)
DateTime start = formatter.parseDateTime("08/11/2017 12:30");
System.out.println(start.toString());
The output will be:
2017-11-08T12:30:00.000-02:00
Notice that the offset (-02:00) is different from yours. That's because DateTime uses the default timezone if you don't specify one.

LocalDate - How to remove character 'T' in LocalDate

How to remove T in my localDate?
I need to remove the 'T' to match data in my database.
This is my code
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss", Locale.US);
String strLocalDate = patientDiagnosisByDoctor.getDiagnosisDateTime().toLocalDateTime().toString();
LocalDateTime localDate = LocalDateTime.parse(strLocalDate, formatter);
System.out.println(localDate);
I got this output:
2015-10-23T03:34:40
What is the best way to remove the 'T' character? Any idea guys?

Use a DateTimeFormatter to format the value of LocalDateTime the way you want it...
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss", Locale.US);
String strLocalDate = "2015-10-23T03:34:40";
LocalDateTime localDate = LocalDateTime.parse(strLocalDate, formatter);
System.out.println(localDate);
System.out.println(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss").format(localDate));
System.out.println(DateTimeFormatter.ofPattern("HH:mm:ss yyyy-MM-dd ").format(localDate));
Which prints...
2015-10-23T03:34:40
2015-10-23 03:34:40
03:34:40 2015-10-23
Remember, date/time objects are just a container for amount of time which has passed since a fixed point in time (like the Unix epoch), they don't have a internal/configurable format of their own, they tend to use the current locale's format.
Instead, when you want to present the date/time value, you should first use a DateTimeFormatter to format the date/time value to what ever format you want and display that
I need to remove the 'T' to match data in my database.
Opps, missed that part.
In this case, you should be converting your Date/Time values to use java.sql.Timestamp and using a PreparedStatement to insert/update them

String localTime = "2018-09-13 00:00:00";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss", Locale.ENGLISH);
LocalDateTime date = LocalDateTime.parse(localTime, formatter);
String replace = date.toString().replace("T", " ");
System.out.println(replace);
2018-09-13 00:00

Simple option using the Joda-Time library.
new LocalDateTime(DateTimeZone.forID("Europe/London")).toString().replace("T", " ");

Convert ms into a string date with Java 8

I have a timestamp as ms and format this with a SimpleDateFormater like this:
SimpleDateFormat sdfDate = new SimpleDateFormat("MM/d/yyyy h:mm a");
return sdfDate.format(new Date(timeStamp));
Now I'd like to change this to use the new Java 8 abilities. Seems like I really can't find a way to get this working with the new Java 8 Classes. Anyone got a hint?

If all you have is a millisecond value (assuming from the Unix Epoch) you can get an LocalDateTime using something like:
LocalDateTime ldt = LocalDateTime.ofInstant(Instant.ofEpochMilli(timeInMillis), ZoneId.systemDefault());
System.out.println(ldt);
Which can print something like:
2015-09-29T16:57:40.077
You can then format it using something like this:
System.out.println(ldt.format(DateTimeFormatter.ofPattern("MM/dd/yyyy h:mm a")));
Which can print something like (based on the original time from the previous example):
09/29/2015 4:57 PM

I hope you can try this in Java 8 to get Date from timestamp:
timeStamp.toLocalDateTime().toLocalDate();
For formatting you can use LocalDateTime as:
String str = "1997-03-18 11:30";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
LocalDateTime dateTime = LocalDateTime.parse(str, formatter);

Java SimpleDateFormat parse Timezone like America/Los_Angeles

I want to parse the following string in Java and convert it to a date:
DTSTART;TZID=America/Los_Angeles:20140423T120000
I tried this:
SimpleDateFormat sdf = new SimpleDateFormat("'DTSTART;TZID='Z':'yyyyMMdd'T'hhmmss");
Date start = sdf.parse("DTSTART;TZID=America/Los_Angeles:20140423T120000");
And this:
SimpleDateFormat sdf = new SimpleDateFormat("'DTSTART;TZID='z':'yyyyMMdd'T'hhmmss");
Date start = sdf.parse("DTSTART;TZID=America/Los_Angeles:20140423T120000");
But it still doesn't work. I think the problem is in America/Los_Angeles.
Can you help me please?
Thank you

Try this one using TimeZone.
Note: You have to split your date string before doing this operation.
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd'T'hhmmss");
TimeZone tz = TimeZone.getTimeZone("America/Los_Angeles");
sdf.setTimeZone(tz);
Date start = sdf.parse("20140423T120000");
In SimpleDateFormat pattern Z represent RFC 822 4-digit time zone
For more info have a look at SimpleDateFormat#timezone.

If you look for a solution how to parse the whole given string in one and only one step then Java 8 offers this option (the pattern symbol V is not supported in SimpleDateFormat):
// V = timezone-id, HH instead of hh for 24-hour-clock, u for proleptic ISO-year
DateTimeFormatter dtf =
DateTimeFormatter.ofPattern("'DTSTART;TZID='VV:uuuuMMdd'T'HHmmss");
ZonedDateTime zdt =
ZonedDateTime.parse("DTSTART;TZID=America/Los_Angeles:20140423T120000", dtf);
Instant instant = zdt.toInstant();
// if you really need the old class java.util.Date
Date jdkDate = Date.from(instant);

JodaTime String yyyy-mm-ddThh:mmss.Z to DateTime

hi i am using Joda time to convert my string dates to DateTime objects.
I currently have the following string:
2014-02-16T00:17:20.000Z
how do i convert this to a DateTime object?
I have tried:
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ssZZZ");
DateTime dt = formatter.parseDateTime("2014-02-16T00:17:20.000Z");
But i am getting the following error:
java.lang.IllegalArgumentException: Invalid format: "2014-02-16T00:17:20.000Z" is malformed at ".000Z"
Any help is greatly appreciated

For future visitors, simpler solution:
String date = "2014-02-16T00:17:20.000Z";
DateTime dateTime = new DateTime(date);

This format happens to be the ISO date time format, that DateTime uses by default. You just need
DateTime d = DateTime.parse(s);
or
DateTime d = DateTime.parse(s, ISODateTimeFormat.dateTimeParser());

Might be issue is you guys using Z(zone) in caps
i have tested below code works well
SimpleDateFormat formatter= new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSz", Locale.ENGLISH);
Date date =formatter.parse("2016-09-06T08:35:02.530GMT");
DateTime d = new DateTime(date.getTime());
