How can I close core thread in ThreadPoolExecutor?

If I use unbounded LinkedBlockingQueue in ThreadPoolExecutor and set the core pool size to 5. When more than 5 tasks are submitted, there will be 5 threads created to handle the request. After finish, these threads will not be closed. How can I make the threads in core pool be closed when finishing their job? I couldn't use maximum pool for that I do need an unbounded queue.

If you really want that functionality, set the core pool size to 0, the maximum pool size to 5 or greater, and the keepAliveTime to 0L. This will remove excess threads as soon as their tasks have completed.
It's very wasteful though if you plan on executing the tasks repeatedly to create new threads everytime you submit a task. One of the benefits of using a thread executor is not having to construct and start a Thread object everytime you run a task.
Brushfire,

  • How can I close 'current' window and not all windows?

    How can I close the current window (only) and not all or none?
    This function works well with MS Explorer.
    Not a problem, just a desired function.

    Hi JLCluster,
    If you just click the small x in the tab you are currently viewing, it will close only that tab. I think you are clicking the x in upper right hand corner of the screen which closes all open tabs as you described.
    Hopefully this helps!

    Do a malware check with some malware scan programs. You need to scan with all programs because each program detects different malware. Make sure that you update each program to get the latest version of the database before doing a scan.

  • How can you close all pages in safari?

    On my iPad it is possible to close all windows in Safari.
    Is there a similar feature in Safari? Every time I clear the history, the last page remains open.
    How can I close that window as well without having to first create a new blank one?
    Regards

    Yes, ok, but then I still have to open a new page to continue browsing.
    on the iPad i can close all pages and safari for iOS defaults to favorites.

  • What should I do if the iphoto keeps on saying that "Plz wait for import to complete" when i click the close button but it is not importing photos? How can I close the iPhoto? I try to switch my mac off but it doesn't work. Thanks.

    You should be able to select Force Quit from the menu beneath the Apple icon in Finder
    and choose to Quit iPhoto from there, without messing up the Mac OS X in the process.
    OS X - Support
    Not sure if rebuilding the iPhoto library would help this issue. However if you had to
    turn off the computer without the correct method (unplug, etc; instead of menu choice)
    the system may have accrued damages and should be checked, maybe repaired by
    use of the Disk Utility in the system. Or restart the computer in Safe Boot mode, then
    run 'repair disk permissions' while it is running in that reduced mode; then restart after.

    There likely are other means to rectify troublesome applications, including reinstall.
    Be sure to backup your music, image, video, and other work on an external drive
    or suitable device as a precaution against loss should there be a hard drive failure.

  • How can I close DatagramSocket?

    I have DatagramSocket in my WP 8 project. I can open it and receive data but there is no Close() method even though MSDN says it exists. How can I close the socket?
    If I go to the definition of DatagramSocket I see this text at the top of the page:
    #region Assembly Windows.winmd, v255.255.255.255
    // C:\Program Files (x86)\Windows Phone Kits\8.0\\Windows Metadata\Windows.winmd
    #endregion
    The version number seems a bit weird. Am I using wrong assembly?

    If you are programming with C#, you can call datagramSocket.Dispose(), that is the C# projection of
    Close().

    >
    There is a mechanism built into subVIs and subVI calls to open when
    called and close when finished. This still works fine for many tasks
    and is quick and easy. To use this, you can use the File>>VI Properties
    on your subVI, go to Window Appearance, Customize, and it is in the left
    column near the bottom.
    You can also set this on a subVI call by right clicking, choosing SubVI
    node setup and set the same Open when called and Close on exit settings.
    The difference between them is that the first will affect every usage of
    the VI, whereas the
    second can be set to pop open sometimes and other
    times not.
    Of course there is another way, introduced when the VI server was added.
    There is a VI property for the VI class, Front Panel Window Open.
    Setting it to True and FALSE will open and close. There is also now a
    method for opening and closing with a few additional options.
    The VI Server allows for more control and flexebility, but the first two
    options are still perfectly valid for simple things. If using them,
    closing your subVI is as simple as exiting your outer loop of your
    subVI. This returns and closes the window all at once giving control
    and and data parameters back to the caller. If using the VI Server, you
    can either close the window just before returning or leave it to the
    caller. Just be sure they are in agreement.

    You are right in the fact of the programmer must make a exit mechanism. However, this is not a bug, this feature is related to the management of this windows type (modal). Bye

  • How can I close a category in the form central form without closing it as error?

    How can I close a category in the form central form without closing it as error?

    I'm still not sure I follow - let me see if this is right.  You want to have users signing up for something using a FormsCentral form and then when something is full you'd like that section to show as "Closed" or full so nobody else can sign up for that particular event/day/time?  If that is the goal FormsCentral does not have any logic to close certain portions of the form.
    Thanks,
