In the below example code:

fun main() = runBlocking {
    val job = launch {
        repeat(1000) { i ->
            println("job: I'm sleeping $i ...")
            delay(500L)
        }
    }
    delay(1300L) // delay a bit
    println("main: I'm tired of waiting!")
    job.cancel() // cancels the job
    job.join() // waits for job's completion 
    println("main: Now I can quit.")
}

How does Kotlin stop execution of launch code block?

A CancellationException is thrown.

Thanks Louis 🙂

Is there a way to know that launch is canceled from inside?

[louiscad]

You can check isActive while catching CancellationException, but do you really need to do so?

[kalpeshp0310]

No, I was just trying to understand how exception flows and how coroutine cancels job.
