String datetime convert to LocalDateTime object

Nimantha :

I want to convert to this string to LocalDateTime object. How can I do that?

"Thu Aug 29 17:46:11 GMT+05:30 2019"

I already try something, but it didn't work.

    final String time = "Thu Aug 29 17:46:11 GMT+05:30 2019";
    final String format = "ddd MMM DD HH:mm:ss 'GMT'Z YYYY";

    DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern(format);
    LocalDateTime localDateTime = LocalDateTime.parse(time, dateTimeFormatter);

Exception in thread "main" java.lang.IllegalArgumentException: Invalid format: "Thu Aug 29 17:46:11" at org.joda.time.format.DateTimeFormatter.parseLocalDateTime(DateTimeFormatter.java:900) at org.joda.time.LocalDateTime.parse(LocalDateTime.java:168)

Ole V.V. :

Note that Joda-Time is considered to be a largely “finished” project. No major enhancements are planned. If using Java SE 8, please migrate to java.time (JSR-310).

This is quoted from the Joda-Time home page. I should say that it endorses the answer by Basil Bourque. In any case if you insist on sticking to Joda-Time for now, the answer is:

    final String time = "Thu Aug 29 17:46:11 GMT+05:30 2019";
    final String format = "EEE MMM dd HH:mm:ss 'GMT'ZZ YYYY";

    DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern(format)
            .withLocale(Locale.ENGLISH)
            .withOffsetParsed();
    DateTime dateTime = DateTime.parse(time, dateTimeFormatter);
    System.out.println(dateTime);

Output:

2019-08-29T17:46:11.000+05:30

In the format pattern string
- You need EEE for day of week. d is for day of month.
- You need lowercase dd for day of month; uppercase DD is for day of year
- I have put in ZZ because according to the docs this is for offset with a colon; Z works in practice too
Since Thu and Aug are in English, you need an English speaking locale. Since I believe your string comes from Date.toString() originally, which always produces English, I found Locale.ROOT appropriate.
I found it better to parse into a DateTIme. To preserve the offset from the string we need to specify that through withOffsetParsed() (you can always convert to LocalDateTime later if desired).
