Quartz cron expression - set start and end times?

Question

Java

Good day ... I
need the ability in Java to run tasks that would be scheduled at a certain interval, I tried the quartz library for this, using Cron Expressions, but they are not suitable for all cases ... For example, you need to run a task every day from 18.20 to 22.50 every 5 minutes…
Please advise either a library that could do this, or some methods that can be used to create Cron Expression for such cases… Thanks in advance…

Answer 1

In the job itself, check that 18:20 <= new Date() <= 22:50
After that, create a task with an interval: 0 0/5 18,19,20,21,22 * *?
This means to run every 5 minutes. from [18 to 23) hours.

Answer 2

Thank you, the idea is interesting ... Apparently, you will have to make a wrapper for the task and use SimpleTrigger in it ...
