Question

I have a java package,
I want to my program be runned every night at 0 o’clock automaticlly,
how can I do this work?

Answer 1

Generally you have 2 solutions:

1. Create application that runs your code every night, i.e. implement scheduling yourself. Obviously you can (and should) use tools that help you to do scheduling.
2. Use OS-specific tools. For example cron for unix and windows task scheduler for windows.
