How to run a task on specific days of the week at a certain time in java?

Question

I would like my users to be able to choose which days of the week they want to schedule a certain task to run in Java. As I understand, the ScheduledExecutorService is only able to run a single execution, or execute at fixed rates. I am able to run a task every day at a specific time, but haven't figured out how to do that for specific days.
Is there a way to run my task on specific days of the week (eg mon, wed, fri)?

Also, I know that there are 3rd party libraries out there that would do well for what I'm asking, such as Quartz, but I'm wondering if there is a way to do this using only Java APIs.
