Convert date using joda time and ignore time

Question

Using the below code I'm attempting to convert a time: "2014-10-31T23:59:59" to just "yyyy-MM-dd" format, so in this case "2014-10-31" .

Here is the code :

import org.joda.time.DateTime;
import org.joda.time.format.DateTimeFormat;
import org.joda.time.format.DateTimeFormatter;

public class TestConvert {

    public static void main(String args[]){
        DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd");
        DateTime dt = formatter.parseDateTime("2014-10-31T23:59:59");
        System.out.println("formatted date is "+dt.toString());
    }

}

exception :

Exception in thread "main" java.lang.IllegalArgumentException: Invalid format: "2014-10-31T23:59:59" is malformed at "T23:59:59"
    at org.joda.time.format.DateTimeFormatter.parseDateTime(DateTimeFormatter.java:899)
    at (TestConvert.java:11)

How to ignore the time and just create a date?

Answer 1

You need a different formatter to parse the date in its original format:

public static void main(String args[]){
    DateTimeFormatter parser = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss");
    DateTime dt = parser.parseDateTime("2014-10-31T23:59:59");

    DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd");
    System.out.println("formatted date is " + formatter.print(dt));
}

Answer 2

Try this:

DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss");
DateTime dt = formatter.parseDateTime("2014-10-31T23:59:59");
System.out.println("formatted date is "+dt.toLocalDate());
