Unparseable date: "2018-08-02T14:24:40.040353"

Question

I am trying to parse a DateTime from C# to Java. Here is what comes as string from the java call "2018-08-02T14:24:40.040353". When I try to parse it, I get the following error Unparseable date: "2018-08-02T14:24:40.040353"

Here is the method for parsing the date

public static String dateFormater(String dateFromJSON, String 
    expectedFormat, String oldFormat) {
    SimpleDateFormat dateFormat = new SimpleDateFormat(oldFormat);
    Date date = null;
    String convertedDate = null;
    try {
        date = dateFormat.parse(dateFromJSON);
        SimpleDateFormat simpleDateFormat = new 
        SimpleDateFormat(expectedFormat);
        convertedDate = simpleDateFormat.format(date);
    } catch (Exception e) {
        e.printStackTrace();
    }

    return convertedDate;
}

What are the parameters you're using in the function call? oldFormat should look something like "yyyy-MM-dd'T'HH:mm:ssZ" — Eric Yang, Aug 07 '18 at 12:36

You are missing the most important information - the precise value of `oldFormat` — Gyro Gearless, Aug 07 '18 at 12:53
FYI: You are using terrible old date-time classes that were supplanted years ago by the *java.time* classes. — Basil Bourque, Aug 07 '18 at 15:37

Your date look like a ISO_LOCAL_DATE_TIME, If you are using Java8 you can use java.time API and use the default format of LocalDateTime like this :

String dateString = "2018-08-02T14:24:40.040353";
LocalDateTime ldt = LocalDateTime.parse(dateString);

ldt.toString():

2018-08-02T14:24:40.040353

Even if you are using Java 6, you can use a backport of JSR-310. +1 – Peter Lawrey Aug 07 '18 at 12:58

Yes @PeterLawrey I use this library in my old projects, it is really helpful – YCF_L Aug 07 '18 at 13:03
Does it have any alternative because i am using it in android and the Call requires API level 26 – Kristiyan Gergov Aug 08 '18 at 05:20
