For each loop with multidimensional arrays?

Hi.I have a problem with for each and multidimensional combination.
public class TestCards
static int[][] dizi={{1,2},{3,4}};
static int t ;
public static void main(String[]args)
     for (int[] i : dizi)
     System.out.println(i);
The result of the codes above is like this
[I@9304b1
[I@190d11
In other words the result is now integer.It has some strange chars which i dont know
Pls help me !

You're printing an array. Arrays don't override toString.
- You could iterate over both dimensions and print each value yourself.
- You could iterate over one dimension and call java.util.Arrays.toString to print a row at a time.*
- You could call java.util.Arrays.deepToString to print the entire thing in one shot.
*The second option is closest to what you're doing now.

  • For-each loop with colon in group name

    When making my first simple RTF report with XML Publisher, I am encountering problems with an XML tag name that contains a colon. When I set the tag name as the group for a loop - <?for-each:Blah1:Blah2?>, where Blah1:Blah2 is the tag name in my XML file, I get an error - java.lang.reflect.InvocationTargetException ... caused by oracle.xdo.parser.v2.XPathException: Namespace prefix 'Blah1' used but not declared. Any help would be appreciated.

    Hi JW
    The colon denotes that you XML is using a namespace and you need to declare in in your template. Just check out the user guide for namespaces. Its pretty straigntforward. I also touched on it in the latest blog entry here, http://blogs.oracle.com/xmlpublisher

  • For Each Loop Load Dynamic Excel Files

    Hi All,
    SSIS 2005
    I want to load excel file .xls one at a time files that have different names without having to select the file in the connection manager, every time. So a user can easily place the excel file in the folder and right the sql job and it loads the file data.
    The data flow tasks all work when I manually select the excel file, but I am unable to get this to work dynamically.
    I have setup a for each loop with multiples data flow tasks and sql tasks to load my data from file.
    Variables:
    @filename d:\new file\*.xls
    For Each Loop:
    ForEachFile Enumerator
    Folder: d:\new file\
    Files: *.xls
    Retrieve File Name: Fully Qualified
    Variable Mappings:
    User::filename (index 0)
    Connection Managers:
    Excel Connection Manager: Expressions, ConnectionString @[User::filename]
    Error Message: Error at new buyer(package name) the connection string format is not valid. it must consist of one or more components of the form X=Y, seperated by semicolons.
    Can anyone assist thanks.

    You still need the file name variable.
    ExcelFilePath is the fully qualified file name of your Excel file. ie. it contains both the path and file name.
    e.g. D:\inbox\myExcelFile.xls
    All the steps you mentioned are correct, except you need to set the property of ExcelFilePath of the Excel connection to the variable that you map to in the ForEach Loop:
    Connection Managers:
    Excel Connection Manager: Expressions, ExcelFilePath @[User::filename]
    Hope this helps.

  • Using IF in a for each loop which is grouped by two fields

    Hi ,
    My requirement is to filter the Payment records ,based on the parameter input date and also group by based on two of the Fields and calculate the sum of the payment Amounts.
    I have created a for each loop with the group by first on one field and then the other field.
    My question is where should I put my IF condition based on parameter dates ?
    If condition would be if Created = Date Parameter .CAn anybody help where I should insert the IF condition in the below code.
    Ex:
    <?for-each-group:Payments;./Created?>
    Display Date : Created
    <?for-each-group:current-group();./CreatedByName?>
    Table      :      CreatedByName     count of Payments           Sum of Amount
    <?end for-each-group?>
    <?end for-each-group?>
    thanks.

    Hi ,
    I got the result by putting the filter in [ ]
    Ex:
    <?for-each-group:Payments[PaymentStatus != 'New';./CreatedDate?>
    here I am filtering the records based on [Payment Status != New] and then group by Created Date .
    Similarly I can new another condition as well in the same statement
    <?for-each-group:Payments[PaymentStatus != 'New'][PaymentMethod != 'Cash'];./CreatedDate?>

  • Custom List with for-each loop

    How do I get a list I am making to be able to be used with a for-each loop?

    As far as I know there is no "for-each" loop in Java, there is however a "for" loop. Is that what you're referring to?
    To use a for loop, let's say you have an array like the following, you could iterate through it like this:
    String[] str = new String[]{"a", "b", "c", "d", "e"};
    for (int i = 0; i < str.length; i++)
             System.out.println(str);
    hope this help you get started ;-)                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               

  • For each loop to print a 3D array

    I want to display the elements of my 3d uniform array but after each element I get a "null" also. Any idea why? I've tested with a 2d array and I don't have any problem. Any help is really appreciated.
    public class Testari {
         public static void main(String[] args) {
              String[][][] my3DArray = new String[3][2][2]; 
                 my3DArray[0][0][0] = "a"; //3d uniform array
                 my3DArray[0][1][0] = "b";
                 my3DArray[1][0][0] = "c";
                 my3DArray[1][1][0] = "d";
                 my3DArray[2][0][0] = "e";
                 my3DArray[2][1][0] = "f";
                 for(String[][] x : my3DArray) {//for each loop
                      for(String[] y : x){
                           for(String z : y){
                                System.out.println(z + "  ");  
    }

    What's 3 x 2 x 2?
    How many elements did you explicitly set?
    How many elements does that leave with their default value of null?

  • SQL Agent Permssions With SSIS for each loop not looping through files

    Hi I am Having trouble getting a ssis package to iterate through a file directory using a proxy account set up in Sql Server.
    So I have a package that loops over csv files. If I run the package manually or set the sql agent job to run as Sysadmin the pakage runs fine all files are processed.
    However if I use the proxy account. the package completes but no files are processed. there are no failures, there is no error handling set up in the control flow. the for each loop container simply does not recognise any files when run under a proxy.
    Note: the proxy is set up with credentials to access the folder. the credential is also set up with the server admin server role... still nothing
    i'm not sure is this is a ssis or permissions problem?
    Any comments will be appreciated

    Can you check this and see if you've configured all the steps correctly
    http://www.mssqltips.com/sqlservertip/2163/running-a-ssis-package-from-sql-server-agent-using-a-proxy-account/
    Also enable logging in package and see if you're getting any error messages obtained in output table/file based on the logging option you chose.

  • How to use for each loop in XSLT when my source is a multilayout file and db

    How do I use a for each loop in XSLT when my source is multilayout file and db .
    My multilayout file is basically contain 2 kind of data one for employee and another for dependent.
    Now my requirement is I want to read each line of data whether it is it is employee or dependent do a join with db and write it in my target file.
    eg :  File content
    1 RichaKumari 311289 TCS INDIA
    2 KiarnKumar 456782 BRO RichaKumari 311289 INDIA
    2 Ravi            456882 BRO RichaKumari 311289 INDIA
    eg : db Content
    311289 RichaKumari TCS INDIA Bangalore [email protected]
    Now in Final File I need something like this :
    1 RichaKumari 311289 TCS INDIA
    2 KiarnKumar RichaKumari 311289 TCS INDIA
    2 Ravi            RichaKumari 311289 TCS INDIA
    here 1 and 2 are the identifier which will decide which layout to follow .

    Hi,
    I think you'll need two nested for-each's... Something like...
    <xsl:for-each select="$root/row[layout = 1]">
    <xsl:variable name="employee" select="."/>
    ... write employee ...
    <xsl:for-each select="$root/row[layout = 2 and dependentid = $employee/id]">
    ... write dependent ...
    </xsl:for-each>
    </xsl:for-each>
    Cheers,

  • Loading accdb file using for each loop in to single target table

    I have 3 accdb file as below in single folder, in control flow I have created a for each loop to loop through all the below file.  In dataflow task I have created oledb source using connection manager to point to first file a1.accdb. I am trying
    to load all the file into single below mentioned target table, here It is only loading first file it is not looping through other two file.
    This I have tried to load .txt files and csv files it is working perfectly but similarly when I try to load access db file table it is not working, can any one of you help me?
    1. a1.accdb contains only one table  a1tab ( col1 col2 col3 )  
    2. a2.accdb  contains only one table  a2tab  ( col1 col2 col3 )
    3. a3.accdb  contains only one table  a3tab   ( col1 col2 col3 )
    I have a target table with similar structure as source
    Target table <TargetTable> Col1 Col2 Col3
    aak

    Thanks Arthur, please find below response
    How do you handle the different table names?  Cant we handle it in a similar manner, how we handle the .csv/.txt files with different name and similar structure for sources(multiple files) and target (single table)
    Is it good to drop the idea of for each loop and create a separate task for each accdb file? to be loaded to same target table( performance wise etc.. any justification would be helpful)
    You must handle the connection string dynamically?
    Can you help me with the logic for handling connection string dynamically
    aak

    How should I do then? I don't want to go through all the list each time an object is removed, I want it to restart where it stopped.

    Not the best solution but something like thisshould work:

  • For Each Loop: Enumerator Configuration In the For each loop Editor Help needed

    Hi All,
    I have a package that runs and updates a table with everytime someone adds a flat file in the source folder. One of the requirement is to upload files with the following
    ACA Flat files will have a naming convention of “ACA_ccyy_<julian date>”  : How can I add this?
    Under Files this is how I have setup the qualifies "ACA_*.*"
    Is there anyway to pass the entire naming convention in the file section? If so how can I ?
    Please help?
    FM

    As you have ACA_*.* set in Files Filter, it will return all the files from the folder which start with ACA_.
    You can have one dummy Sequence Container inside FE Loop Container. Connect it to your starting task and do right click on Precedence Constraint and write the expression the way you want by using SSIS functions. If the expression is evaluated to True only
    then it will go to the next task.
    In this way you can skip Non-ACA files.
    Please refer:
