81. Coroutine exception handling: SupervisorJob and exception propagation

Image
🌊 Coroutine Exception Handling: SupervisorJob and Exception Propagation in Kotlin Welcome, Kotlin developers! Understanding exception handling in coroutines is crucial for building robust and resilient concurrent applications. Today, we'll dive deep into the intricate world of coroutine error management, exploring SupervisorJob and advanced exception propagation techniques. 🔍 Understanding Coroutine Exception Mechanics In Kotlin coroutines, exception handling differs significantly from traditional synchronous programming. When an exception occurs in a child coroutine, it can potentially cancel the entire parent coroutine and its siblings, which can lead to unexpected application behavior. // Standard Coroutine Exception Propagation suspend fun standardExceptionPropagation() { val job = CoroutineScope(Dispatchers.Default).launch { launch { throw RuntimeException("Child coroutine failed") } launch { ...

80. Structured concurrency in Kotlin: Parent-child relationship

Image
🌿 Structured Concurrency in Kotlin: Understanding Parent-Child Relationship Kotlin's structured concurrency provides a robust mechanism for managing coroutines and their complex relationships. This article explores the intricate parent-child relationship in coroutine hierarchies, offering insights into effective concurrent programming. 🔬 Fundamentals of Structured Concurrency Structured concurrency ensures that child coroutines are managed within the lifecycle of their parent coroutine. This approach prevents resource leaks and provides predictable control over concurrent operations. import kotlinx.coroutines.* suspend fun main() { val parentCoroutine = CoroutineScope(Dispatchers.Default) val job = parentCoroutine.launch { // Parent coroutine launch { // Child coroutine 1 delay(100) println("Child 1 completed") } launch { // Child coroutin...

79. StateFlow and SharedFlow in Kotlin: Hot stream implementations

Image
🌊 StateFlow and SharedFlow: Advanced Kotlin Coroutine Streams Welcome, Kotlin developers! Today we'll dive deep into two powerful hot stream implementations in Kotlin Coroutines: StateFlow and SharedFlow. These mechanisms provide robust solutions for handling complex asynchronous data flows and state management in modern reactive programming. 📘 Understanding Hot Streams Unlike cold flows that generate values on-demand, hot streams emit values independently of collectors. This means multiple subscribers can receive the same stream of data simultaneously. 🔥 StateFlow: Single State Management val counterState = MutableStateFlow(0) // Updating state counterState.value = 10 // Collecting state changes lifecycleScope.launch { counterState.collect { value -> println("Current state: $value") } } • Always has an initial value • Represents single, current state • Automatically removes dupl...
