Timer vs. ScheduledExecutorService scheduling

Question

One of the recommended uses of the ScheduledExecutorService is as a direct replacement for the Timer class, as discussed in numerous StackOverflow topics already:

• Java Timer vs ExecutorService?
• Difference between TimerTask and Executors.newScheduledThreadPool(1)
• What is the difference between schedule and scheduleAtFixedRate?
• Android Timer schedule vs scheduleAtFixedRate

However, the naming conventions of the methods supported by ScheduledExecutorService and Timer, are not identical. For example, whereas they both have a scheduleAtFixedRate() method, the Timer method

• schedule​(TimerTask task, long delay, long period)

does not have a namesake counterpart.

Is the ScheduledExecutorService method

• scheduleWithFixedDelay​(Runnable command, long initialDelay, long delay, TimeUnit unit)

the one to use instead?

Answer 1

https://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ScheduledExecutorService.html#scheduleAtFixedRate(java.lang.Runnable,%20long,%20long,%20java.util.concurrent.TimeUnit)

Creates and executes a periodic action that becomes enabled first after the given initial delay, and subsequently with the given delay between the termination of one execution and the commencement of the next.

https://docs.oracle.com/javase/7/docs/api/java/util/Timer.html#schedule(java.util.TimerTask,%20long,%20long)

Schedules the specified task for repeated fixed-delay execution, beginning after the specified delay. Subsequent executions take place at approximately regular intervals separated by the specified period.

I would say - Yes ;-)
