Setting a custom pool of threads by using the asCoroutineDispatcher function on Java’s ExecutorService.
import kotlinx.coroutines.*
import java.util.concurrent.Executors
suspend fun suspendTask1() {
println("Start task1 | Thread ${Thread.currentThread()}")
yield()
println("End task1 | Thread ${Thread.currentThread()}")
}
suspend fun suspendTask2() {
println("Start task2 | Thread ${Thread.currentThread()}")
yield()
println("End task2 | Thread ${Thread.currentThread()}")
}
fun main() {
Executors.newSingleThreadExecutor().asCoroutineDispatcher().use { context ->
println("Start main")
runBlocking {
launch(context) { suspendTask1() }
launch { suspendTask2() }
println("Called task1 and task2 from ${Thread.currentThread()}")
}
println("End main")
}
}
