# coroutines

[franztesca]

I'm on JVM, I have two coroutines that needs to access a mutable state exclusively. I can choose between using synchronized or a Mutex. Both work. Which one should I use? On one side, synchronized can block the thread of a coroutine but it's much faster, on the other side Mutex never blocks the thread but it's slower. Is there a preferred option, in general? Thanks

You could also use a MutableStateFlow, which uses synchronized under the hood.
