Once you have the tasks created with their associated MDC values, you can submit them to the thread pool for execution. Make sure to use an appropriate thread pool implementation, such asExecutorService, to manage the threads. importjava.util.concurrent.ExecutorService;importjava.util.concurrent.Exec...

To use this method, simply pass theExecutorServicereference to this method. ExecutorServiceexecutorService=Executors.newFixedThreadPool(1);executorService.submit(newWorkerTask("1"));executorService.submit(newWorkerTask("2"));executorService.submit(newWorkerTask("3"));shutdownAndAwaitTermination(executorServic...
Currently, Java doesn’t provide a standard API to schedule virtual threads as we do with other concurrent APIs like the ScheduledExecutorService’s schedule() method. So, to effectively make our virtual threads run scheduled tasks, we need to write our own scheduler. 3.1. Scheduling Virtual Thr...
We can also use thegetmethod of aFutureinstead of using aTimer: Here, we used theExecutorServiceto submit the worker thread that returns an instance ofFuture, whosegetmethod will block the main thread until the specified time. It’ll raise aTimeoutExceptionafter the specified timeout. In the...
Learn to use JavaThreadPoolExecutorin combination withBlockingQueue. 1. CreatingThreadPoolExecutor AThreadPoolExecutoris a type ofExecutorServicethat executes each submitted task using one of the threads from a thread pool. This class provides many flexible ways to create a pool of threads in differe...
Another solution or more of a workaround is to use theExecutorServiceframework to limit the number of threads in a thread pool that can be handled at a given time. Example: importjava.util.concurrent.ExecutorService;importjava.util.concurrent.Executors;importjava.util.concurrent.TimeUnit;importjav...
