Number format exception when parsing string to long

Question

I am trying to parse string to long as follows:

Long _id_long= Long.valueOf(_id);

The error message:

java.lang.NumberFormatException: For input string: "DT31988159" at java.lang.NumberFormatException.forInputString(Unknown Source) at java.lang.Long.parseLong(Unknown Source)

That string isn't a valid long. It has characters that aren't numbers. — forgivenson, Nov 17 '14 at 17:41
@Asaf: so, it means that it's impossible to parse "DT31988159" to long? — Klausos Klausos, Nov 17 '14 at 17:48
Yes, you have to remove all the non numeric characters. For example: _id = _id.replaceAll("DT",""); — Asaf, Nov 17 '14 at 17:51

Have you read the JavaDoc of Long.valueOf(String)? You will find NumberFormatException.

Thrown to indicate that the application has attempted to convert a string to one of the numeric types, but that the string does not have the appropriate format.

Just remove the prefix.
