    Default Double.valueof wont work for formated string

    Hi all

    I got a noob question as I am a begginer in java and new to the forum! I bet its a simple matter but it seems to trouble me

    so I got this String say "123,456.78" which I am trying to store inside a Double but I am getting a numberformatexception. the programm will understand the "123456.78" string but not the one with the thousand seperator!
    I guess one option would be to get rid of the "," but I would like this to be clever and depend on my local/regeional setings, so regardelss of the decimal/thousand symbols the program to be able to understand that the above string can be a Double.

    any advise/guideline?

    thanks!
