Need to remove dashes ("-") from a String value provided by the user

Dear Fellow Java developers:

I am trying to develop a method that validates a number that is given by a user.  The number is nine characters in length, and allows the user to send it in either of the following formats:

1. xxxxxxxxx
2. xxx-xxx-xxx

The validation method needs to check to see if there are dashes ("-") within the number, and if it finds any, then it should remove all occurrenes, then check to see if the number is 9 characters in length, and then return that number back.  

Please help.

s = s.replaceAll("-", "").trim();
if (s.length() == 9) {
   // valid
