Learning Concurrency in Kotlin

Combining contexts

For example, let's say that you want to have a coroutine running in a specific thread, and at the same time you want to set an exception handler for it. To do this, you can combine both by using the plus operator:

main(args: Array<String>) = runBlocking {    val dispatcher = newSingleThreadContext("myDispatcher")    val handler = CoroutineExceptionHandler({ _, throwable ->        println("Error captured")        println("Message: ${throwable.message}")    })    launch(dispatcher + handler) {        println("Running in ${Thread.currentThread().name}")        TODO("Not implemented!")    }.join()}

In this case, we are combining a single thread dispatcher with an exception handler, and the coroutine will behave accordingly:

You can, of course, create a variable to ...
