Sleep in Kotlin

This article explores different ways to sleep in Kotlin.

1. Using `Thread.sleep()` function

To set the current thread to sleep, we can use the Thread.sleep() function. It takes in the total number of milliseconds to sleep, and can be used as follows:

fun main() {

println("Stopping…")

try {

// sleep for one second

Thread.sleep(1000)

} catch (e: InterruptedException) {

e.printStackTrace()

}

println("Resuming…")

}

Output:

Stopping…
Resuming…

2. Using `TimeUnit`

Alternatively, we can use the sleep() function of TimeUnit which automatically converts the specified time unit into the form required by the Thread.sleep() function. To sleep in seconds, use TimeUnit.SECONDS.

import java.util.concurrent.TimeUnit

fun main() {

println("Stopping…")

try {

// sleep for one second

TimeUnit.SECONDS.sleep(1)

} catch (e: InterruptedException) {

e.printStackTrace()

}

println("Resuming…")

}

Output:

Stopping…
Resuming…

Similarly, to sleep in milliseconds, use TimeUnit.MILLISECONDS. The TimeUnit offers a total of 7 Time units i.e, NANOSECONDS, MICROSECONDS, MILLISECONDS, SECONDS, MINUTES, HOURS, and DAYS.

import java.util.concurrent.TimeUnit

fun main() {

println("Stopping…")

try {

// sleep for 500 milliseconds

TimeUnit.MILLISECONDS.sleep(500)

} catch (e: InterruptedException) {

e.printStackTrace()

}

println("Resuming…")

}

Output:

Stopping…
Resuming…
