In aboveJava TutorialThe consumers (not the producer) should lock the buffer when reading the packet (but not when acquiring the semaphore) to prevent race conditions. In the example below the producer also locks the list since everything is on the sameJVM....
In the realm of multithreaded or asynchronous programming, managing shared resources safely poses a common challenge. What happens when multiple threads or coroutines vie to update the same value simultaneously? Enter Mutex (Mutual Exclusion), Kotlin coroutines’ solution to this conundrum. ...
