Hi, is there a method which converts a string to a long integer?

String s = "88888888888888888888888888888888888888888";
long l = Long.parseLong(s);

It looked good until..

Exception in thread "main" java.lang.NumberFormatException: For input string: "
4905"

There's a character space before the number. Does java have a quick fix, or do I have to use RegExp?

What about .trim() method of String class?

That will remove leading and trailing spaces.

Cheers,
Dian

If the String could be null, make sure you check for null before performing trim() !

sedj is right on...good practice to surround your trim() and parseXXX() methods with try/catch to handle both null AND invalid entries (in your case, non-numeric). Then you can exchange that ugly java generated exception with a more user-friendly message and/or corrective logic.
