What methods can be used to manage and handle exceptions in Kotlin Coroutines?

In Kotlin Coroutines, several main methods are used for managing and handling exceptions:

1. try-catch inside a coroutine — you can wrap coroutine code in a try-catch block for local exception handling.

launch {
    try {
        // code that may throw an exception
    } catch (e: Exception) {
        // handle exception
    }
}

2. CoroutineExceptionHandler — a special handler that can be passed into the coroutine context for global handling of unhandled exceptions in coroutines launched via launch (does not work with async).

val handler = CoroutineExceptionHandler { _, exception ->
    println("Caught $exception")
}

GlobalScope.launch(handler) {
    throw RuntimeException("Error")
}

3. supervisorScope and SupervisorJob — allow isolating errors of child coroutines so that an exception in one does not cancel others.

4. async and await — exceptions that occur in async will be thrown when calling await, and can be handled with try-catch around await.

Thus, the choice of method depends on the context and requirements for error handling in coroutines.
