Instead, after garbage collection, the objects are queued for finalization, which occurs later. In the Sun implementation, finalizers are executed by adaemon thread. If the finalizer thread cannot keep up with the finalization queue, then the Java heap could fill up and an OOM could be thrown...
Java ThreadPoolExecutor & BlockingQueue example to run a demo task with fixed size thread pool. Also, learn to use RejectedExecutionHandler.
When the task is submitted in aForkJoinPool, the process will be divided into smaller processes and pushed to a shared queue. Once thefork()method is invoked, tasks are invoked in parallel until the base condition is true. Once processing is forked, thejoin()method ensures that threads wait...
