What methods of task execution in Coroutines do you know?

In Kotlin Coroutines, tasks can be performed in several ways:

• launch — starts a new coroutine that runs concurrently and does not return a result. Used for background tasks where no result is needed.

• async — starts a coroutine that returns a result as a Deferred, allowing you to get the result via await(). Suitable for parallel computations with a result.

• runBlocking — blocks the current thread until the coroutine completes, often used in main functions or tests.

• withContext — switches the execution context (for example, to Dispatchers.IO for input/output operations) and executes a block of code, returning a result.

Example:

import kotlinx.coroutines.*

fun main() = runBlocking {
    launch {
        delay(1000)
        println("Task in launch")
    }

    val result = async {
        delay(500)
        42
    }

    println("Result of async: ${result.await()}")
}
