Have you tried using Timestamp.valueOf(String)
? It looks like it should do almost exactly what you want – you just need to change the separator between your date and time to a space, and the ones between hours and minutes, and minutes and hours, to colons:
import java.sql.*;
public class Test {
public static void main(String[] args) {
String text = "2011-10-02 18:48:05.123456";
Timestamp ts = Timestamp.valueOf(text);
System.out.println(ts.getNanos());
}
}
Assuming you’ve already validated the string length, this will convert to the right format:
static String convertSeparators(String input) {
char[] chars = input.toCharArray();
chars[10] = ' ';
chars[13] = ':';
chars[16] = ':';
return new String(chars);
}
Alternatively, parse down to milliseconds by taking a substring and using Joda Time or SimpleDateFormat
(I vastly prefer Joda Time, but your mileage may vary). Then take the remainder of the string as another string and parse it with Integer.parseInt
. You can then combine the values pretty easily:
Date date = parseDateFromFirstPart();
int micros = parseJustLastThreeDigits();
Timestamp ts = new Timestamp(date.getTime());
ts.setNanos(ts.getNanos() + micros * 1000);
