How come Java methods can only return one variable?

Hi,
I am just curious, how come C/C++/Java methods/functions can only return one argument but can accept many parameters.
I know that the workaround is to return an object, but sometimes creating a class is just too much overhead.
Thank you in advance.

Hello,
It's an interesting discussion. To get the full answer to your question, you'd have to consult the library and find books on programming language design and implementation.
I believe the tradition goes all the way back to the first programming languages having subroutines/procedures/functions/methods in them: you can return nothing at all (void i Java) or a single value. The need for returning a single value, I guess, comes from the wish to embed calls in arithmetic expressions:
  res = 2 * someObject.foo(x) - anotherObj.bar(a,b);To my knowledge, few languages allow you to return more values. One that does is BETA (see www.daimi.au.dk/~beta/). Though not indispensable, it's convenient sometimes. I don't know why it's not more widespread.
Yours,
Ole

  • How come My Sites can only be created when logged directly onto the Sharepoint Server?

    Hello Community
       In Synchronization I populate the container with OU's that contain
    Service accounts, user accounts created in the Sharepoint farm and a
    domain local group containing a OU with all of the trusted user accounts.
       AFter populating the container I perform a User Profile Synchronization.
       After the User Profile Synchronization finishes MIISClient shows "success"
    including the OU containing the trusted user accounts.
       Although I cannot Find all of the trusted users individually in Manage User Profile I
    can find them with the peoplepicker when I add them to the web application
    and the My Site Host application.
       The problem is if I logon directly onto the Sharepoint server with an account created
    in the Sharepoint farm I can create a My Site with that account. But if a trusted user
    logs onto their computer and tries to create a My Site they get an error stating
    the page can't be displayed.
        Even if I click "sign on as a different user" on the trusted user computer
    and with a user account that was created in the Sharepoint farm and try to create a
    My Site I get the error stating the page can't be displayed.
        The reason the page can't be displayed on the trusted users computer is because although
    it can access the My Site Host application it cannot access its default.aspx page.
        So the question is how come when creating a My Site the My Site Host default.aspx page
    cannot be accessed from the trusted user computer but when creating a My Site directly on
    the Sharepoint Server the default.aspx page can be accessed and the trusted user and/or the
    user account created in the farm can access the default.aspx page and create a My Site?
        Thank you
        Shabeaut

    What does that mean "trusted user computer"?
    How many servers you have in farm?
    Are you using a single domain or there are multiple domains involved ?

  • How can I make a pdf book with "camera to pdf" option on phone? I can only convert one pic at a time

    How can I make a pdf book (single pdf file with several pages)  with "camera to pdf" option on phone? I can only convert one pic at a time. ( Or )how can I attach all those pictures converted pdf's into one pdf file which obviously results in to a single pdf file with several pages in it ?

    Adobe Reader on the iPhone is a PDF reading app. It's not a creation app.
    You need to get an app like Pages which is intended for page layout. It can place pictures from the phone and export PDF.

  • ITunes tells me "Could not be used because the original file could not be found. Would you like to locate it?"  I can locate it and all my other music, but can only open one song at a time.  How do I set it to open all my music whenever I want it?

    iTunes tells me my song selection: "Could not be used because the original file could not be found. Would you like to locate it?"  I can locate it and all my other music, but can only open one song at a time.  How do I set it to open all my music whenever I want?

    I just spent several hours dealing with this when switching to a new PC. It was extremely frustrating as I knew my files were on my external HD but no matter how many times I copied my old iTunes folder over the files were still missing...because dummy me had forgotten to "unhide folders" on my new PC and my old files were actually stored in a hidden folder created long long ago.
    This is how I did it on Windows 7 with iTunes 10
    1. Look in iTunes Advanced Preferences to see where iTunes is saving files. (Edit, Preferences, Advanced)
         Example: C:/Users/Woildbill/My Music/iTunes/Music
    2. Ensure you are able to see hidden files - Control Panel, Folder Option, View, Show Hidden Files
    3. Use Your Computer's Search Function to Locate the Missing File (Start, Search, type name of song - I started my search in "My Music" folder but be sure to expand to entire Computer if not found right away)
    4. In Search Results, right-click found folder and select properties. This will tell you where the file is actually stored.
    5. Use Windows Explorer (right-click start) to navigate to the location of the file. It is likley your other missing files are in the same location.
    6. In Windows Explorer, copy the newly located files to the iTumes location from Step 1 and everything should work again.
    Hope this helps!

  • I had 2 games of clash of clans on 1 game centre.  Now I can only see one?  How can I find the other one?

    My kids had 2 games of clash of clans on 1 game centre.  Now I can only see one?  How can I find the other one?
    My daughter set up a game centre on her ipad.  My son, on his ipad used the same game centre log in.  He then set up his own game of clash of clans.  After my son set up his Clash of Clans, my daugher set up her own Clash of Clans using the same game centre log in on her ipad.  Both were using the Clash of Clans successfully on their own ipads using the same game centre log in. 
    One day my son signed into someone elses Clash of Clans, since then he is unable to go back to his Clash of Clans and can only see his sisters.
    Please let me know if this can be resolved.
    We wish to delete my daughters Clash of Clans - as she does not use it at all.  We would like to regain access to my sons. 
    My son can visit his Clash of Clans - his clan name is 'The Big Boys'  He has a shield that is blue with a yellow lightning from top right to bottom left.  His name is Fat Poo (I know ridiculous).
    If you can help us or advise us what to do we would make my son very happy
    thanks

    Thanks for taking a stab at it: that didn't prove to be the problem. That option in the settings for tabbed browsing was not checked.
    I may be a bit behind the times: I am used to tabbed browsing showing all the tabs it possibly can, instead of just the last one. Sometimes it won't even show the last tab: I can have 15 tabs open, and not see a single tab. I've been confused by this into closing a window with lots of tabs open, because it looks like a single page-window.
    My main problem with the tab-bar flashing to the end of the row is that it means a great deal more mouse-clicking around to browse.
    I haven't tried installing the latest beta. Maybe that would fix the problem.

  • How to approve the request only for one time for human task in BPM Worklist

    Hi,
    Following are the some important points you should understand about ESS Leave Request Workflow
    1. The Visualization ( how should it appear in UWL and what should happen when you click on a particular workitem) is defined in SWFVISU. Check for TS12300097. Generally, it invokes com.sap.xss.hr.lea.appl/LeaveRequestApprover Java WebDynpro application. Just check whether you are able to get the correct Leave Processing application called when you execute your workitem from UWL?
    2. In general it should have option to process the leave request either approve/reject. When the leave request gets approved/rejected the status of the Leave Request document gets changed ( in workflow it is &REQ.STATUS&
    3. There is a need to schedule a background job for program RPTARQPOST which will pick up all the documents in APPROVED status and creates an absence record for the same.
    4. Apart from schedule job as mentioned above, you also have to schedule a background job for program  RPTARQEMAIL, which is basically used to send e-mails for all the documents which are yet to be approved to correct manager.
    as you say , you can not see Approve/Reject options from UWL, it looks to me that correct javawebdynpro application is not being called for this task. Just check this !!
    Good Luck !!
    Regards

  • I have two apple accounts, but can only access one. I did all the steps to recover the older account's password but nothing worked. I need to access the older account to update apps. Also would there be a way to just combine both accounts?

    I have two apple accounts, but can only access one. I did all the steps to recover the older account's password but nothing worked. I need to access the older account to update apps. Also would there be a way to just combine both accounts?

    Were you able to reset the account's password ? If not then how did you try to get it reset e.g. http://iforgot.apple.com (which would have sent it to the rescue email address if you have one on that account) ? You can also try contacting iTunes Support in your country to get it reset : http://support.apple.com/kb/HT5699
    And no, accounts can't be merged nor content transferred between accounts.
