Can you guys tell me any specific coding standard has
to be followed here(i guess i need not hard code the
pwd's)More than just the passwords. Why are the driver class and URL hard-coded?
I wouldn't use this class. It's not very useful as written. It's a poor abstraction for one. There's lots of other useful things that you could include, like methods for closing and rolling back a connection, closing a statement and result set. You don't log any exceptions or messages. You preclude the use of a connection pool managed by an Java EE app server.
