Setting default values for Method Parameters (Like in C++)

Hello. In Java can I define a method like...
public boolean AddCommand(int commandType, ObjectClass object = null) {
    // Some code here.
    return true;
}So that I can call it with
ObjectClass object = new ObjectClass();
result = AddCommand(2, object);or with
result = AddCommand(2);I know I can do it with C/C++ which is the language I have experience with.

I would think this would be a better example of default methods and constructors using this:
public class MyClass{
    int myInt = 0;
    MyOtherClass m = null;
    MyClass(){  //no argument constructor
      this(defaultWhatever, defaultMyOtherClass);//call real constructor
    MyClass(int myInt){  //one argument
      this(myInt, defaultMyOtherClass);//call real constructor
    MyClass(int myInt, MyOtherClass m){  //actual constructor
     this.myInt = myInt;
     this.MyOtherClass = m;
    public void myDefaultMethod()
        this.myRealMethod(defaultValue);
    public void myRealMethod(int val)
        System.out.println(val);//do work with val
}I try to avoid default methods and such anyways. It's not hard to pass in regularly used values, better than hiding the implementation.

  • Extending flash: how do I set default values for filenames

    Hi,
    I am trying to set default values for filenames
    <choosefile> and <popupslider>s that will show up when
    my XMLpanel first loads in my jsfl extension file. It seems that I
    can only set default values for textbox items.
    How do I do this for filenames and popups?
    As a workaround, I also tried using a flash object dialog box
    to look like a <choosefile>, or any jsfl command, but then
    how do I return those values back to the XMLpanel that calls them.
    and pass the data back to my jsfl script.
    lemme know if you know a way,

    Create two constants for the Allocate Mode input (right click > create > constant). Place one in the true case of the case structure, and place the other one in the false case. Wire them to the same tunnel (border of the case structure), then wire the tunnel to the Allocate Mode terminal of the AO Config. I don't have Traditional DAQ installed, but that should do it.

  • Set default value for parameter fields

    Good day!
    Situation:
    1. I have 2 parameter fields in reports (dateFrom and dateTo)
    2. Before running report in ASP.NET I change value this fields (dateTo = today, dateFrom = today - 3 days)
    3.I use for this source:
    foreach (ParameterField crParam in CrystalReportSource1.ReportDocument.ParameterFields)
                            CrystalDecisions.Web.Parameter crParametr = new CrystalDecisions.Web.Parameter();
                            string ParametrName = crParam.Name;
                            crParametr.Name = ParametrName;
                              crParametr.DefaultValue = ActionReportParameter.GetParametrValue(ReportName, ParametrName);
                             CrystalReportSource1.Report.Parameters.Add(crParametr);
    4. And repurt run without request value parameter fields.
    5. BUT!!! now I need request value parameter fields before report start running - I want set default values for filelds and offer user change its before report start run.
    How do this?
    Thanks

    I believe you need to create your own parameter promt screen. Capture what the user entered and pass that to the report(?).

  • Is there any way we can set default value for a Date Attribute to current date in Master Data Services

    Is there any way we can set default value for a Date Attribute to current date in Master Data Services.
    I as well wants to know that is there any posibility to show Calendar control while input data into respective date attributes.
    Thanks.

    Hi Anagha,
    So far i havent found any way to set todays date by default from MMI, but i guess this flow should work as workaroud
    1. Add buisness rule which can set a default value when Date = NULL/Blank
    2.get the entity table ,use -select EntityTable from mdm.tblEntity where Name = '<enter entity name>'
    3.Go to that table and add a after update trigger like
    if uda_<entityid>_<attributeid(Date attribute)> = default value
    update uda_<entityid>_<attributeid(Date attribute)> =getdate() where id = <LastUpdatedRow>
    I will check on this too from my side.
    By the way AFAIK i dont think so calendar control integration is possible .

  • Setting default values for item in opportunity mgmt(crmd_bus2000111)

    Hi All,
    I need to set default values for the field Fiscal Quarter in item level using BADI CRM_CUSTOMER_I_BADI .This Field is created using EEW. The default value is like if the date is nov-2007 the value for this fiscal period is FQ4-2007 .
    Any clue would be great help..

    Why don't you try setting the default value in the List next to the Matrix - item 107
    Item 107 is a matrix (a transposed one), I have no idea what list you mean...  I am using item 107, not 112. Item 112 is used only to detect a click on the "Add Record" button, which is the last row of the matrix 112.
    I don't see the gender column in the grid and I'm also unsure of the id you have for it "12" - are you sure it's correct ( i usually use Item("columnName") )?
    Sorry for the confusion. "12" is the name of the standard column "Password" which we have renamed to store the gender.

    Hi,
    According to your description, you want to set default value for TaxonomyWebTaggingControl.
    I have a test in my environment. It could be achieved by setting the Text Property of TaxonomyWebTaggingControl.
    Here is the code snippet:
    TaxonomySession session = new TaxonomySession(SPContext.Current.Site);
    SPSite site = SPContext.Current.Web.Site;
    TermStore termStore = session.TermStores["Managed Metadata Service"];
    Group group = termStore.Groups["GroupA"];
    TermSet termSet = group.TermSets["A"];
    Term term = termSet.Terms["A1"];
    TaxonomyWebTaggingControl1.SspId.Add(termStore.Id);
    TaxonomyWebTaggingControl1.SSPList = termStore.Id.ToString();
    TaxonomyWebTaggingControl1.TermSetId.Add(termSet.Id);
    TaxonomyWebTaggingControl1.TermSetList = termSet.Id.ToString();
    TaxonomyWebTaggingControl1.AllowFillIn = true;
    TaxonomyWebTaggingControl1.IsAddTerms = true;
    TaxonomyWebTaggingControl1.IsMulti = false;
    TaxonomyWebTaggingControl1.Text = string.Format("{0}|{1}", term.Name, term.Id.ToString());
    Here is a detailed article for your reference:

  • How to hide PNP selection windows and set default values for PNP.

    Hi expert,
         I am using HR logical database PNP, but I don't want to display selection windoes for running program on PNP, whereas I want to set default value for some selection items in the program. could you please tell me how to get those two targets?
    Many Thanks,

    Hi
    You have mentioned 2 things.
    1. Don't want selection windows for running program for PNP - this can be achieved using the HR Report category - You can get more details on HR Report Category on
    HR Report Category
    2.  I want to set default value for some selection items - This you need to achieve in initialization event of your program.
    How you can get this can be explained by INITIALIZATION (SAP Library - ABAP Programming (BC-ABA))

  • Can you set default values for person/group picker fields? To current user?

    Two-part question/issue . . .
    Part 1:
    In InfoPath 2013 in use with SharePoint 2013, how do you set a Default Value for Person/Group Picker fields? Other field types like Text Boxes have a Default Value section in the Data tab of Properties.  There doesn't appear to be any equivalent for
    the Person/Group Picker field type in Properties.  I'd like to set a default person for a few fields in a form I've created.  Is this possible?
    Part 2:
    The default user I want to set for one of those Person/Group fields is the "current user."  I want a user to log into our SharePoint 2013 intranet, load a new form for edit/creation, and have one of the Person/Group fields in that form to
    automatically populate this particular user.  Is this possible?

    Hi Stephen,
    You can auto populate your InfoPath farm with current user Name and all other property that you have in your User profile, you have couple of options.
    First you can make a secondary connection in your InfoPath form with user profile and can use the UserProfileService.asmx and call the GetUserProfileByName method. Here is the steps you can follow.
    http://blogs.technet.com/b/anneste/archive/2011/11/02/how-to-create-an-infopath-form-to-auto-populate-data-in-sharepoint-2010.aspx
    Secondly you can use JQuery and SPServices ,
    $().SPServices.SPGetCurrentUser function to populate the values with script to achieve the same in this case you no need to use InfoPath form just create simple text type column in SharePoint
    list and auto populate it with getting the current user Name from User Profile here is the scripts
    <script language="javascript" type="text/javascript" src="../../jQuery%20Libraries/jquery-1.4.2.min.js"></script>
    <script language="javascript" type="text/javascript" src="../../jQuery%20Libraries/jquery.SPServices-0.5.4.min.js"></script>
    <script language="javascript" type="text/javascript">
    $(document).ready(function() {
      var userCurrentName = $().SPServices.SPGetCurrentUser({
        fieldName: "CurrentUser"
      $("input[Title='CurrentUser']").val(userCurrentName);
      var userPhone = $().SPServices.SPGetCurrentUser({
        fieldName: "WorkPhone"
      $("input[Title='Phone']").val(userPhone);
    </script>

  • Set default value for product type

    I want to set default value in product type drop  down box
    in component PRD01QR.
    view  SearchHelp.
    I tried with setter and getter , but not working
    they are using query string.

    Hi,
    You can achieve this by redefining the method GET_VH_PRODUCT_TYPE() in IMPL class of searchHelp view. Just copy paste the implementation of this method from super class and now control the internal table as per your requirement like
    comment out the line       APPEND INITIAL LINE TO lt_ddlb. (line no: 47)
    as it will add an empty line at the starting of internal of product type values which you dont want. In you case there should be some default value for product type field, so arrange the inetrnal table values according to you requirement and what ever value you want to default for product type that should be the first value in the drop down without empty line and add an empty line at the end of the internal table.
    No need to call super->GET_VH_PRODUCT_TYPE() in your implementation as you have written all the required code in your implemenation itself.
    Hope this would help you!
    Regards,
    Ajay

  • How to set default value for vc2_255_arr in plsql parameter directive?

    Hi,
    I would like to set a default values for a plsql parameter which is of vc2_255_arr type. How to do that?
    Below is the example from PL/SQL Server Page.
    +" To set a default value, so that the parameter becomes optional, include a default="expression" attribute in the directive. The values for this attribute are substituted directly into a PL/SQL statement, so any strings must be single-quoted, and you can use special values such as null, as in the following example:+
    +<%@ plsql parameter="p_last_name" default="null" %> "+
    My plsql parameter is p_arr which is of "TYPE vc2_255_arr IS TABLE OF VARCHAR2(255) INDEX BY BINARY_INTEGER"
    *<%@ plsql parameter="p_arr" type="PMP_LIB.VC2_255_ARR" %>*
    Thanks in advance!
    kwong

    My plsql parameter is p_arr which is of "TYPE vc2_255_arr IS TABLE OF VARCHAR2(255) INDEX BY BINARY_INTEGER"You need to declare it in a package specification and initialize in the package body:
    SQL> create or replace package pmp_lib
    as
       type vc2_255_arr is table of varchar2 (255)
                              index by binary_integer;
       vc2_255_arr_default   vc2_255_arr;
    end pmp_lib;
    Package created.
    SQL> create or replace package body pmp_lib
    as
    begin
       vc2_255_arr_default (1) := 'abc';
       vc2_255_arr_default (2) := 'def';
    end pmp_lib;
    Package body created.
    SQL> declare
       arr   pmp_lib.vc2_255_arr := pmp_lib.vc2_255_arr_default;
    begin
       for i in 1 .. arr.count
       loop
          dbms_output.put_line (arr (i));
       end loop;
    end;
    abc
    def
    PL/SQL procedure successfully completed.so in your case it would probably be sth like (assuming pmp_lib is a package):
    <%@ plsql parameter="p_arr" type="PMP_LIB.VC2_255_ARR" default = "PMP_LIB.vc2_255_arr_default" %>
