Convert String to Date format with timezone throwing parsing error

I have String s1 as below.

String s1 = "2021-10-12T14:28:46.615+00:00"

I want to convert it to exact same java.util.Date instance - 2021-10-12T14:28:46.615+00:00

Using below is returning "2021-10-12T14:38:15.000-0400"

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.sss");
Date d1 = dateFormat.parse(s1);

And using below is throwing parsing error

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.sssZ");

Date d1 = dateFormat.parse(s1);

Pls advice the dateformat I should be using

Here is one way if you must use the legacy (and deprecated) Date class. But you should focus on using the java.time package.

String s1 = "2021-10-12T14:28:46.615+00:00";


OffsetDateTime odt = OffsetDateTime.parse(s1);
long epochMilli = odt.toInstant().toEpochMilli();
Date date = new Date(epochMilli);
System.out.println(date);

prints

Tue Oct 12 10:28:46 EDT 2021

Note that since the offset is +00:00 the timezone is for UTC/Greenwich and adjusted accordingly. If required, you can use .plusHours() or .minusHours() on the value returned by parse to adjust the offset based on locality.
