parsing using SimpleDateFormatter

I have a date formatted like this 2018-07-13T16:06:46+00:00. I would like to convert it to long.

I tried the following code and it gives me parse exception. 

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
Date dt = formatter.parse("2018-07-13T16:06:46+00:00");

Can someone please help?

Thanks.

I would like to convert it to long

It seems you have a problem with the format of your date, If you are using java.time API it can be more easier, you can just use the default format of OffsetDateTime like this :

String stringDate = "2018-07-13T16:06:46+00:00";
OffsetDateTime ofset = OffsetDateTime.parse(stringDate);
Instant instant = ofset.toInstant();
long millisecond = instant.toEpochMilli();
System.out.println(millisecond);//1531498006000

or you can make it in one shot :

//parse the date and convert it to long (It seems you want to get millisecond)
long millisecond = OffsetDateTime.parse("2018-07-13T16:06:46+00:00")
                                 .toInstant()
                                 .toEpochMilli();

This being a standard data format in java 8 you could try:

ZonedDateTime parsedDateTime = ZonedDateTime.parse("2018-07-13T16:06:46+00:00", DateTimeFormatter.ISO_OFFSET_DATE_TIME);
System.out.println(parsedDateTime.toEpochSecond());

Can verify what @Sun has posted, as I came to the same conclusion. The following code works on my system: 

import java.util.Date;  
import java.text.ParseException;  
import java.text.SimpleDateFormat;  

public class DateFormatter {  

    public static void main(String[] args) {
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssXXX");
        try {
            Date dt = formatter.parse("2018-07-13T16:06:46+00:00");
            System.out.println(dt);
        } catch (ParseException e) {
            System.out.println(e);
            e.printStackTrace();
        }
    }
}
