Answer 1

change your mask to

DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSS");

so you have

java.sql.Timestamp timeStampDate = null;
String dateString = "2018-10-17T22:37:10.000+0000";

try {
    DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
    Date date = formatter.parse(dateString);
    timeStampDate = new Timestamp(date.getTime());

} catch (ParseException e) {
    e.printStackTrace();
}

By the way you should not need to cast the Date

Apologies for my slackness, in my haste I did not test the output and as per @andreas comment, the correct mask is actually yyyy-MM-dd'T'HH:mm:ss.SSSZ

Answer 2

java.time

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("uuuu-MM-dd'T'HH:mm:ss.SSSXX");
    String dateString = "2018-10-17T22:37:10.000+0000";
    OffsetDateTime odt = OffsetDateTime.parse(dateString, formatter);

    System.out.println("Parsed datetime: " + odt);

Output from this code is:

Parsed datetime: 2018-10-17T22:37:10Z

For saving into MySQL it’s good to use a datetime object, but the Timestamp class has design problems and is now long outdated. I am sorry that I don’t have the experience with MySQL, but I think the following should work:

    PreparedStatement ps = myDatabaseConnection.prepareStatement(
            "insert into my_table (my_timestamp) values (?)");
    ps.setObject(1, odt);
