Java supports multithreading out of the box. This means that by running bytecode concurrently in separate worker threads, the JVM is capable of improving application performance. Although multithreading is a powerful feature, it comes at a price. In multithreaded environments, we need to write imple...
where tasks are scheduled in one thread and executed in another, with each maintaining its own stack trace. The IDE now prints a merged stack trace in the console instead of only the worker’s stack trace, making it easier to trace the flow of execution. This enhancement is enabled by def...
currentWorker.submitToLocalQueue()—adds the task to the local queue of the Worker thread and waits for execution. Worker Worker is the thread of Kotlin coroutine. The implementation of Worker inherits Thread, which is essentially an encapsulation of Java threads. We conclude that the Worker is...
