Date, time and timestamp

[Yudi Lukman]

Hi, I'm new to Java programming and I want to use date and time type for my database. I use MS Access as my database. Is there anyone have a complete program using date, time, or timestamp ? I can't understand if it's only a part of the program. Afterall, I'm really new. Thanks.

Hi Yudi,
You may get some clues from the following code. Please note that in the code "JDBCMsAccessConnection" represents a class that establishes connection to the database.
Good luck,
Smitha
