Initializing a protected field in a subclass doesn't work

Why doesn't this work? And if it shouldn't, how do I get around it?
public abstract class Ship
     protected double rotationSpeed;
     protected aMethod()
          System.out.println(rotationSpeed);
public abstract class Cruiser
     protected double rotationSpeed = 3;
}I thought that when the method 'aMethod' it would print out '3' but it doesn't. I'm not sure why, I also tried this:
public abstract class Cruiser
     public Cruiser()
          rotationSpeed = 3;
But it didn't change it. How do I alter protected fields like this?

Awesome, thanks, using super worked.You're welcome.
Note that you don't need to use the 'super' keyword:
class Cruiser extends Ship {
    public Cruiser() {
        rotationSpeed = 3; // this works too
}but I find it clearer to use it.
I didn't think it really mattered if I posted the code running it. I didn't really have one. The names of those fields and classes aren't real.
...IMO, it's best to post an SSCCE of the problem/question.

  • Painter doesn't work with Trading Partner's Business Area COSP-PARGB

    Hello,
    i valorized field PARGB through FI substitution (Tcode GGB1) and it works fine.
    PARGB is valorized in BSEG, COEP and COSP for CO totals records for reporting.
    In GR22 i activated PARGB in Characteristics screen for Library 6O1 (internal orders).
    I created a report copying standard report 6O01-001 and i put in General Data Selection field PARGB.
    The selection screen doesn't work!
    The field appears and F1 functionality calls COSP-PARGB and it's correct.
    I tried to use fix values rather than variables (standard or custom), but the extraction doesn't work.
    The system doesn't filter by Trading partner's Business Area.
    Please, does anybody know something in matter?
    Thanks,

  • The query doesn't work

    Hi kind people!
    I have udf  TEST on the picture. The query on the picture I have connected to the field Test and conected to field description too. But with the field Description the query doesn't work. U_Producer is the name of another field. Why does not it work?

    Hi Gordon!
    From the right I have UDF for choosing the spare parts of auto.  I want to add a spare part, for example to item master data (OITM). I enter every field step by step 1 - 4 by choosing frome use tables linked in every field. I choose fielf 1 (Brand) for example TOYOTA and in the use table of 2(Model) field i see only values that belong to TOYOTA that to say corolla, carina, vista and so on.  But to find any component  exactly i put on the loupe in the field 5 and see a table where all types of auto parts in the world but they are filtered with parametrs in 1-4 fields. I chhose needed component and get in the 5 field any code of a choosed part. Then i d liked to link the table of filed 5 to field Description too and to filter component with code in field 5 in order to get item description from the use table. I used the one method of filtering in all fields Here i see that i can to filter values using use fields but I don't use it in standart field description, although the usual selection of elements of any use table works. As a result a see that the problem that doesn't work the selection and filtration in the field description but it works in in UDF.

  • Outlook advanced search & Exchange 2013 - "Sent to...." field doesn't work correctly in online mode?

    Hello,<o:p></o:p>
    We've come across what seems to be a problem with advanced find in Outlook in online mode, when used with Exchange 2013. 
    Using the "Messages" tab of "Advanced Find", anything typed into the "Sent to...." field produces no search results.  If the field is populated by clicking
    "Sent to..." and selecting a name from a contact list or GAL, results are returned. 
    eg. 
    Sent items contains messages to "Charlie" who has the email address
    [email protected] and sender is
    "Dave" who has the email address
    [email protected] 
    Entering "charlie" or
    [email protected], (or any previously acceptable partial term such as "charl" or "@contoso.com") into the "Sent to"" field produces no results.  If the user exists in a contact
    list and is selected from it, the search works fine.  The same is true searching the inbox, using the local user's id of "Dave" or
    [email protected]
    We've confirmed this issue occurs at four client's sites, plus our own internal Exchange 2013 CU3 system.  Four of the sites have been transitioned from Exchange 2010, the fifth was a completely new installation.  The problem occurs with Outlook
    2007, 2010 and 2013. 
    This works fine in cached mode (not a solution as our clients are predominantly Citrix/RDS).  Exchange search doesn't report any issues and the index states are all "healthy",
    we've also tried rebuilding the indexes with no improvement.
    Any ideas would be appreciated, or even if someone else can confirm they see the same thing.
    Thanks.

    Hi Winnie,
    Thanks for your reply, and I'm sorry I've not responded earlier.  While this problem is one that's annoying several of our clients, and while I have been doing further testing and investigation, it's had to take a back seat to other more pressing issues
    until now.
    OWA search works fine, as does using "From:" in instant search, and the "From" query on the Advanced tab in Advanced Find.  The search services have been restarted, indexing state and copy status etc are all healthy, the indexes
    have been rebuilt/reseeded, and I've gone through the diagnostics again.  Nothing is logged in event viewer, and the only error that comes up when checking failed index docs for a user are for unsupported format handlers (.png etc).
    The issue seems purely to be with the "Sent to..." field on the Messages tab, it's as if it gets completely ignored.  The search returns instantly with "There are no items to show in this view".  Just to make sure I wasn't losing
    my marbles, I've compared searches on Exchange 2007 and 2010, and on those I can enter as little as a single letter or email domain and receive the expected results.  On 2013 I get nothing whatsoever whatever I enter, unless I pick an address from a contact
    list.
    At this point, I thought that since Office 365 is Exchange 2013 based it'd be worth testing that, and sure enough I got exactly the same issue.  I setup an Office 365/Outlook 2010 profile on a machine that is currently in an existing Exchange 2010
    environment where search works correctly, searching Office 365 doesn't work on that either.
    EDIT - Ignore this bit, a fresh install of Windows 7 and Office 2010 doesn't work with Office 365 either.  I am exploring another avenue.  I setup a fresh Windows 7 VM, installed Office 2010 and connected that to Office 365, search worked fine,
    so I'm now looking into what the difference with that VM and the servers and workstations out "in the wild" could be.  For example, the test VM isn't on a domain, it's not fully patched, it has no additional software installed etc.  Outside
    of Microsoft applications and operating systems and having similar configurations, I haven't isolated a common link across all of our client sites that are affected, there's no single 3rd party application or anti-virus solution in place at all of them for
    example. 
    I'll update with any findings, but if you or anyone else has any idea in the meantime I'd be grateful for your input.
    Regards.

  • Addition doesn't work until both inputs are initialized?

    I'm using a Logitech web camera to take pictures. I want to operate in either of two modes:
    1) Overwrite - each picture taken replaces the previous one
    2) Accumulate - each picture taken is added to the previous one (pixel by pixel)
    The attached .doc shows a simplified version of the VI
    It's working fine except for one thing ... I can't start out in "accumulate" mode. I have to take one picture in "overwrite" mode before "accumulate" mode will begin to work. If I try to begin in "accumulate" mode, the display just sits there blank regardless of how many pictures I take, until I take one in "overwrite" mode.
    Does this must mean that the addition function doesn't work until both inputs are initialized? If I initialized the shift register to an array of zeros would that fix it? I tried it and it didn't seem to help, but maybe I need to make sure the initialization array is the same size as the picture array?
    Thanks

    Look up the rules for addition and you will find that when you add two arrays, you can only add elements that exist(in both arrays). Otherwise, there is nothing to add. If your shift register is uninitialized, then that's your problem.
    Two solutions:
    1... If you know the size ahead of time, then initialize an array of that size with zeroes, and wire that to the outside of your shift reg.
    2... You could detect I = 0, and replace the array with your new data on the 0th iteration, regardless of the mode switch. In other words do not perform an ADD if there's nothing there yet.
    Either one of these is preferable to using the data from an uninitialized Shift reg. The data might not exist, or it might be leftover from your last run an hour ago.

  • How to get protected fields

    Hello,
    I don't know how to get protected fields that a class inherits from its superclass through reflexion ... the getDeclaredFields method seems not working ...
    here is my test program:
    import java.io.File;
    import java.lang.reflect.Field;
    public class Test {
         public static void main(String[] args) {
              Field [] fieldList = SubClass.class.getDeclaredFields();
              for (Field field: fieldList) {
                   field.setAccessible(true);
                   System.out.println (field.getName());
         static class SuperClass {
              protected File file;
              public SuperClass () {
                   file = new File ("a.txt");
         static class SubClass {
              private File myfile;
              public SubClass () {
                   myfile = new File ("b.txt");
    The output is
    myfile
    This means, the getDeclaredField method of the SubClass returns only fields declared by this class, not protected fields declared by its superclass.
    Anyone has an idea to fix the problem, please help me. Thank you a lot
    }

    That's not a problem, the documentation specifically says that getDeclaredFields() only returns fields from this class. If you want fields from the superclass, why not just getSuperclass().getDeclaredFields()?

  • How to hide a field based on the value of a field in a different subform - null check doesn't work!

    I'm using Javascript to set the actions. I need to hide a text field if the value of a field in another sub-form is null.
    - tried checking the value of the other field for null - doesn't work
    - tried setting a variable str2 where I know the value of the other field is available then checking that variable when I initialize the text field - doesn't work
    What am I missing?

    Hi.
    Try this in the originating sub form referring to the text field (X). 
    if (this.rawValue = 1)
              X.presence = "visible";
    else if (this.rawValue = null)
              X.presence = "hidden";

  • MultiProvider report not functioning - overwriting protected field

    Hello,
    I have a multiprovider that combines data from the Sales Overview cube (0SD_C03) with a custom plan cube (data from COPA and SIS).  In writing queries off of the (active) multiprovider, short dumps occur except when only running against one infoprovider.  In other words, if the query is restricted to only show Sales data (0SD_C03), it works fine.  If the query is restricted to only show Plan data (custom plan cube), then it works fine.  However, the intersection of the two does not work - which is the entire functionality of the multiprovider (a join). 
    I've cut the query back to the very basics:  Fiscal Year and one Key Figure (that is present in both source infocubes).   Without specifying or splitting out the InfoProviders, it should combine the data (total the two), but instead creates a short dump.  Using a structure to split Actuals from Plan also results the short dump.  The only way to get the report to actually execute and return is to restrict it to just one InfoProvider.  I tried copying the MultiProvider and starting over, but that did not improve the situation.  The failure occurs after the variable screen has been filled in.  (Also tried w/out variables.)
    Using LISTCUBE, the data is found in a single execution (no filter applied to 0INFOPROV) and splits out to the two infoproviders w/ approp. fiscal year and Key Figure totals.  So there seems to be something at the reporting layer malfunctioning.
    Here's the ST22 short dump:

    forgot my adminpassword, i have tried the reboot with initial disk didn't work, i am able to get into my computer with name and password, but this same name and password doesn't work as an administrators password when i want to download or change things.
    do you have any suggestions? Im about to give up, i can't even access wireless have to use a dsl
    pretty sad

    ... this same name and password doesn't work as an administrators password when i want to download or change things.
    It's probably that your Keychain password is not the same as your login password. If you configured your computer to log you in automatically, you may not have used your login password in so long you forgot it.
    There is no way to retrieve the "login" Keychain password, but you can reset the Keychain from the Preferences menu: select it in the Keychain Access menu and select "Reset My Default Keychain". This will create a new, empty Keychain but the old one will be saved should you ever remember its password.
    The result of this is that you will have to supply passwords for everything that requires it, since without your Keychain they will no longer automatically fill themselves. However, once you supply them and store them in your new Keychain, they will be remembered.

  • Checking the initiality of the fields while creating  entries for a table

    While creating entries using table maintenance generator(TMG) i need to check the initiality of the fields.Are there any such events?
    I know i can go and change in the screen by making it mandatory or by writing a module in the PAI of the screen of table maintenance generator. Both of cases i have to change the TMG which is generated by SAP system. I want to know is there a way to achieve this with out changing the TMG possible events?

    hi rahul,
    as far as i know, you have to do your initial valifdation in TMG and you have to change your TMG. However, if you have checked the initial flag while defining the field, you will not have initial value for that particular field.... (if the field is key field, by default it is not initial)
    hope this helps....
    thanks and regards,

  • Tabbing through form fields in app doesn't work in Firefox.

    Is there a setting in Firefox that permits tabbing through form fields so that one doesn't have to use the mouse? This works fine in IE. for the same app without any configuration, but not in Firefox.

    Are you really still running Firefox 3.6? Since it hasn't received any security updates for nine months, you may be putting yourself at risk.
    In my experience, tabbing through forms works just fine. Have you tested in Firefox's Safe Mode to see whether the problem is caused by a custom setting or add-on.
    First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.org/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
    Next, restart Firefox in [http://support.mozilla.org/kb/Safe+Mode Safe Mode] by holding the Shift key when you double-click the program icon.
    In the Safe Mode dialog, do not check any boxes, just click "Continue in Safe Mode."
    If tabbing works correctly, this points to an add-on or custom setting as the most likely cause of the problem.

  • Password protect fields in interactive pdf

    Hi all,
    I have completed an interactive pdf online form and I want to make one of the sections (several fields) password protected. So two questions:
    How do you password protect fields?
    Do you have to apply password protection to each individual field or can you highlight a section (several fields) and password protect the whole section?
    Would really appreciate some help.
    Thanks so much. . .
