Why set the interrupt bit in a Callable

眉间皱痕 提交于 2019-12-20 05:59:05
问题 So, this resource (http://www.ibm.com/developerworks/java/library/j-jtp05236/index.html) suggest to set the interrupt bit in a Thread when that Thread does not deal with the interrupt itself, " so that code higher up on the call stack can learn of the interruption and respond to it if it wants to ." Let's say I'm using an ExecutorService to run something in a different Thread. I construct a Callable and pass this Callable into ExecutorService.submit(), which returns a Future. If the Callable

问题 I need to make a library in which I will have synchronous and asynchronous feature. executeSynchronous() - waits until I have a result, returns the result. executeAsynchronous() - returns a Future immediately which can be processed after other things are done, if needed. Core Logic of my Library The customer will use our library and they will call it by passing DataKey builder object. We will then construct a URL by using that DataKey object and make a HTTP client call to that URL by

Occasional InterruptedException when quitting a Swing application

落花浮王杯 提交于 2019-12-17 17:55:11
问题 I recently updated my computer to a more powerful one, with a quad-core hyperthreading processor (i7), thus plenty of real concurrency available. Now I'm occasionally getting the following error when quitting ( System.exit(0) ) an application (with a Swing GUI) that I'm developing: Exception while removing reference: java.lang.InterruptedException java.lang.InterruptedException at java.lang.Object.wait(Native Method) at java.lang.ref.ReferenceQueue.remove(ReferenceQueue.java:118) at java.lang

java.lang.InterruptedException using swingworker

♀尐吖头ヾ 提交于 2019-12-13 19:45:12
问题 I am using Swingworker to request value from url address to dynamically change a version of displayed information. At certain cases this worker is cancelled. The problem is that I get java.lang.InterruptedException sometimes (but not every time I cancel worker). I am not sure what to do with it, moreover I have no idea where it is thrown, I cannot debug it because I get it when I do lots of version changes in short time (I use slider and this happens when I am dragging it for some time) .

Under what conditions will BlockingQueue.take throw interrupted exception?

谁都会走 提交于 2019-12-12 08:01:27
问题 Let us suppose that I have a thread that consumes items produced by another thread. Its run method is as follows, with inQueue being a BlockingQueue boolean shutdown = false; while (!shutdown) { try { WorkItem w = inQueue.take(); w.consume(); } catch (InterruptedException e) { shutdown = true; } } Furthermore, a different thread will signal that there are no more work items by interrupting this running thread. Will take() throw an interrupted exception if it does not need to block to retrieve

What is the point of restoring the interrupted status in JCIP listing 7.7?

故事扮演 提交于 2019-12-11 15:57:48
问题 In this code public class NoncancelableTask { public Task getNextTask(BlockingQueue<Task> queue) { boolean interrupted = false; try { while (true) { try { return queue.take(); } catch (InterruptedException e) { interrupted = true; // fall through and retry } } } finally { if (interrupted) Thread.currentThread().interrupt(); } } interface Task { } } I understand that setting the interrupted status lets the caller of this method retain the status of interruption to do something with it

What will happen if you call interrupt() on a sleeping thread?

痴心易碎 提交于 2019-12-11 10:53:05
问题 I have a thread, and on run() I call sleep() . What will happen if I interrupt this thread? MyThread extends Thread{ public void run(){ try{ sleep(1000000); } catch(InterruptedException e) {//} } } I want to clarify the following: If the thread is not yet started, calling interrupt() would do nothing, right? If the thread is started, and is now sleeping, calling interrupt() while sleeping will throw an InterruptedException ; and thus, goes to catch() and then ends the thread, right? 回答1: 1)

Thread.isInterrupted doesn't work, Thread.interrupted does

问题 The following program demonstrates the problem (latest JVM & whatnot): public static void main(String[] args) throws InterruptedException { // if this is true, both interrupted and isInterrupted work final boolean withPrint = false; // decide whether to use isInterrupted or interrupted. // if this is true, the program never terminates. final boolean useIsInterrupted = true; ExecutorService executor = Executors.newSingleThreadExecutor(); final CountDownLatch latch = new CountDownLatch(1);

Does Thread.sleep throw if the thread was already interrupted?

问题 Given a thread which was interrupted while it was not blocked (i.e. no InterruptedException was thrown), does that thread throw an InterruptedException when it later attempts to sleep? The documentation does not state this clearly: InterruptedException - if any thread has interrupted the current thread. The interrupted status of the current thread is cleared when this exception is thrown. 回答1: Yes, it does. The documentation perhaps isn't crystal clear on that point, but this is easy to both

When to use Interrupt Gate or Trap Gate?

Deadly 提交于 2019-12-06 14:47:57
问题 As the Intel Manual illustrated, both Interrupt Gate and Trap Gate can be used to access a handler routine. And some exceptions even share vector numbers with interrupts. I am wondering when such a shared vector is detected by the CPU, how could CPU know whether it stands for an exception or an interrupt? I am kind of confused about the logic among the following things: the decision of the gate types in the IDT the judgement of whether the vector stands for an exception or an interrupt Which
