These functions are normally used in file and network operations as they require callbacks executed on operation completion; also that this function always returns a value. With the...
3. Using ThreadPoolExecutor with BlockingQueue To demonstrate the usage of ThreadPoolExecutor with BlockingQueue, we have created one task DemoTask. This task does nothing. It simply waits for 500ms and then completes. DemoTask.javapublic class DemoTask implements Runnable { private String name ...

. The suspension occurs in the native code (Native), and the virtual machine does not know it at all. Unlike methods such as Java's sleep() or wait() that are explicitly called, the virtual machine can know the true state of the thread, but for the native code. Suspended, the ...

In other words, if we set a small timeout value, awaitTermination() prematurely unblocks like Thread.sleep() does. Indeed, the test is successful when we run it. 6. Using a ThreadPoolExecutor Another option is to create an ExecutorService object that accepts a defined number of jobs and ...
