Hi all,
I should write a program for launching another program.
The launcher should launch the main program at a specific time and date, and stop it in another specific time and date.This operation should be repeated every day or weak or month. Time and date and periods are set by user.
I don't have any clue on how to write such a program in Java.
Is this possible with java? Could some one help me and say how to do this? or if someone has a similar code?

Thanks
