Timed alerts in JTable

[Hikari]

I was wondering if anyone could help me out with this. Basically, I have a JTable with a column of times in it. How would I go about having a sort of reminder alert a minute before each allocated time, containing the name and other info from the rest of that row? And then being able to either snooze it for a minute or cancel it?

Another question, is there any way to have the format type of the column as time format?

I posted my code in another thread already, but since I've amended it somewhat, here it is.

Thank you in advance. :D Sorry for any mistakes I may have made.

Thank you, but I feel I still need some pointers, or someone who can guide me to the right direction.

I'll keep trying, but anyone with any suggestions would be well appreciated.
