Join Ketkee Aryamane for an in-depth discussion in this video ScheduledExecutorService overview, part of Java EE: Concurrency and Multithreading.
- [Instructor] We have seen the Executor,…and we've seen the ExecutorService,…now let's take a look at…the ScheduledExecutorService interface.…It's a sub-interface of the ExecutorService,…and as the name suggests,…it is used to schedule certain jobs, right?…So we just got a special method called a schedule,…which will help you run jobs after a given delay.…So you can actually start a job…after some initial delay and then the job can run for you.…Something like that, okay?…There are two other flavors of methods:…scheduleWithFixedDelay and scheduleAtFixedRate.…
So those are the methods that you may want to employ…if you want to execute your jobs in the application…at periodic intervals or with certain definite delay, okay?…So let's go to the next slide and see…what is the use case that we are going to implement…as a part of this API's demo that we are going to do.…Now when you talk about schedule jobs in your application,…it is generally a very common use case that we have:…clean up and maintenance activities for the application.…
