Answer

Handling exceptions in coroutines depends on the scope and builder.

1. try-catch

The most basic way. Works inside `launch` or `async` (when you call await).

```kotlin launch { try { doWork() } catch (e: Exception) { handleError(e) } } ```

2. CoroutineExceptionHandler

A context element to handle uncaught exceptions in `launch`.

• Note: Does NOT catch exceptions in `async`.
• Note: Only works in the root coroutine or a SupervisorJob.

```kotlin val handler = CoroutineExceptionHandler { _, exception -> println("Caught $exception") } scope.launch(handler) { throw RuntimeException("Boom") } ```

3. Async / Await

Exceptions in `async` are deferred until you call `.await()`. You must wrap the `await()` call in try-catch.
