append variables to a text file

[ddatta8]

Hi,

I have a text file having the following format:
def234 bobby
abc123 jumbo
cde234 katie

I want to append to this text file the data contained by two variables studID and password. How do I do that?
I have tried using

Any help would be appreciated.
Thanks.

use fileWriter (with append property)
with BufferedWriter
use append method to append info
finally call flush method

remember to close writer steam
