Java - String Token

Hi!
I have a text file with the following values.

username:password,security question,security answer

Using string token, i do manage to read in username and password via bufferreader.
But my problems comes when reading security question as it is delimited by a "," instead of a ":"

Is there a way during my buffer reader, read in both : and ,?

Else, how am i going to read my security question and answer.

Any solutions would be great.
Cheers!
