Joda-time from LocalDateTime string to LocalDate

I'm using JodaTime to get the date and time of creation of an account. The format being 

2017-04-05T12:38:35.585

When I get this I store it in my database as a string so I've looked around for ways to format this from a string to LocalDate but haven't been succesful in anything I've found online. My next step is a horrible solution in my opinion to loop through the string until I find the T and remove everything after it. So I'm left with 

2017-04-05.

But Ideally if possible have the date as 

05/04/2017

I'm using joda-time 2.7.

LocalDateTime class has a constructor that takes a String and parses it. Then you just call toString() method with the pattern you want:

String input = "2017-04-05T12:38:35.585";
LocalDateTime d = new LocalDateTime(input);
System.out.println(d.toString("dd/MM/yyyy"));

Output:

05/04/2017

Note: you can also use ISODateTimeFormat to parse and a DateTimeFormatter instead of toString() to get the output:

LocalDateTime d = ISODateTimeFormat.localDateOptionalTimeParser().parseLocalDateTime(input);
DateTimeFormatter fmt = DateTimeFormat.forPattern("dd/MM/yyyy");
System.out.println(fmt.print(d));

The output will be the same.

Use the ISODateTimeFormat to get a LocalDateTime and from this get the LocalDate. Be careful to use the right Locale

String input="2017-04-05T12:38:35.585";

LocalDateTime ldt = ISODateTimeFormat.localDateOptionalTimeParser()
                    .withLocale(Locale.ENGLISH)
                    .parseLocalDateTime(input);

System.out.println(ldt.toLocalDate());//prints 2017-04-05
