Kotlin Coroutines and Flow
Asynchronous programming with Coroutines: launch, async, suspend functions, Dispatchers, Flow, StateFlow, SharedFlow
1What is a coroutine in Kotlin?
What is a coroutine in Kotlin?
Risposta
A coroutine is a lightweight thread that allows writing asynchronous code sequentially. It can be suspended without blocking the thread, allowing other tasks to execute. More efficient than traditional threads.
2What is the difference between launch and async?
What is the difference between launch and async?
Risposta
launch starts a coroutine that doesn't return a result (returns a Job). async starts a coroutine that returns a result via a Deferred (await()). Use async when you need the result.
3What is the suspend keyword used for?
What is the suspend keyword used for?
Risposta
suspend marks a function that can be suspended and resumed later without blocking the thread. These functions can only be called from other suspend functions or coroutines. They enable asynchronous operations.
What is a Dispatcher in coroutines?
When to use Dispatchers.IO?
