Repeatable task in Kotlin

Question

I am writing desktop app using Kotlin and I want to repeat execution of function for every X seconds.

I found solutions with using android library, there is other option? Maybe something like TaskRunner in Java?

SOLUTION

I used Timer().schedule(startAfter, delay){...} easy and simple ;)

No, it's a scheduled executor service. Schedule the task with repetition. — Marko Topolnik, Oct 16 '18 at 10:58

You can use the timer function from kotlin-stdlib

Example of usage:

fun main(args: Array<String>)  {
    val timer = timer(period = 1000) { // period in milliseconds
        println("this task is repeating 10 times")
    }
    Thread.sleep(10000)
    timer.cancel()
    timer.purge()
}

I think the example is wrong. It sleeps 10s and then quits without printing – Tim Oct 16 '18 at 11:31
I have test it before posting the answer and It works – Lionel Briand Oct 16 '18 at 11:33

This is just a wrapper around Java 1.3 `Timer`, superseded by Java 5 `ScheduledExecutorService`. It's OK for basic usage, but each timer starts its own thread. – Marko Topolnik Oct 16 '18 at 11:34

I'm agree to not overuse this method. But OP do not precise how many functions are schedules at various rates. – Lionel Briand Oct 16 '18 at 11:45
Thanks! But I found better solution, please check ;) (main post edited) – ACz Oct 17 '18 at 09:29
