how to update one column of my table?

Dear friends,
I want to read my table and write it again with updated data like(Wed Jan 19 16:26:37 PST 2001 and change it to 1/19/2001)so how can I update this column data through my servlet?
Any advice?
Many thanks,
Elahe

or mybe it is clear to ask this way that how can I read date like this format from database:
Wed Feb 19 16:26:37 PST 2001
Wed Jan 02 12:22:40 PST 2002
and write it like:
2/19/2001
1/02/2002
I need to update all data in date column.
I hope it is clear this time...
Many Thanks,
Elahe

You should read it out of the database as a Date, and then format it for the user:

to update the database, get the formatted String date, parse it into a Date object, write the date object to the database:
