Coroutine examples

This section covers the most common examples of coroutines usage. Here, we will look at how to handle exceptions, close resources, work with channels, and so on. It's important to know how to use coroutines in practice.

This section covers the following topics:

• Exception handling
• Recourse releasing
• Parallel executing
• Lazy executing
• Channels

Exception handling

Coroutines allow us to write asynchronous code in a sequential manner. This includes exception handling, and we can use the usual try {...} catch {...} block to catch exceptions.

The following example shows how to use it in practice:

fun main(args: Array<String>) = runBlocking<Unit> {
    launch {
        val result = try {
        ...
