How create dynamic array?

i have some code....
public static Object[] parseObjectArray( String type, int size ) {
if ( !TypeUtil.isSupportedType( type ) ) {
throw new IllegalArgumentException( "Not supported type:" + type );
try {
     if ( "String".equalsIgnoreCase( type ) ) {
          return new String[size];
     else if ( "Integer".equalsIgnoreCase( type ) ) {
          return new Integer[size];
     else if ( "Long".equalsIgnoreCase( type ) ) {
          return new Long[size];
     else if ( "Float".equalsIgnoreCase( type ) ) {
          return new Float[size];
     else if ( "Double".equalsIgnoreCase( type ) ) {
          return new Double[size];
     else if ( "Byte".equalsIgnoreCase( type ) ) {
          return new Byte[size];
     else if ( "Short".equalsIgnoreCase( type ) ) {
          return new Short[size];
     else if ("BigDecimal".equalsIgnoreCase(type)) {
          return new java.math.BigDecimal[size];
     else if ( "BigInteger".equalsIgnoreCase( type ) ) {
          return new java.math.BigInteger[size];
     else if ( "Boolean".equalsIgnoreCase( type ) ) {
          return new Boolean[size];
     else if ( "Character".equalsIgnoreCase( type ) ) {
          return new Character[size];
catch ( Exception ex ) {
     throw new IllegalArgumentException( "Not compatible value tyep" );
return null;
The problem is it work only J2SE or over.
it don't work on CDC beacause java.math.BigDecimal
That class is not included in CDC
But, my application is intended to work J2SE and CDC
So, i think "use the reflection" but there are no solution that I found.
Class c = Class.forName("[Ljava.math.BigDecimal;");
Object o = c.newInstance();
first line(Class.forName...) work well, but next line raise an Exception
java.lang.InstantiationException: [Ljava.math.BigDecimal;
also, it can not set size to array that is created
anyone know solution, please reply or mail to me!! please!

well I know of a better way to do this in j2se which is using java.util.ArrayList. I dont know if this works in CDC. Hope this helps

Creating dynamic array

Can anybody tell me how to create a dynamic array in Java??I dont want to fix size of array,it should take any number of values at runtime.Please tell me the syntax of using dynamic arrays.

Hi,
For creating an array of similar data elements, use
ArrayList., but for storing elements which are in the
form of object then use Vector...
Best of Luck..
R SWrong... the main different between ArrayList and Vector is that Vector was sychronized and ArrayList are not.

Reflection question: Creating dynamic array classes

I'm trying to create a String[].class dynamically by passing into a method the value "String[]" and then returning the Class, but I can't get my head around creating an array version.
e.g.
public Class classFromName(String className)
return Class.forName(className);
but it fails on arrays passed in. Fine for "String", but not "String[]" or "String[][]".
Is this possible?
Thanks
Mark Fisher ([email protected])

I couldn't get just "String" to work.
But remember that you usually write just "String" in source code because there's an implicit import java.lang.* statement at the beginning of your Java source code. That means that "java.lang.String" is the full name of the class. Imports apply onto to source code and are not "remembered" after the compilation process is finished.
If you want an array of Strings, the JVM name for that class is "[Ljava.lang.String;". I think there's also a way of getting the class object for array types in the reflection classes... I'll let you look for that in the API docs.

How create dynamic URL for every row shown in the report?

Hi,
Iam new to this Application. I created one interactive report to find the number of bugs logged for every product and its sub component for past one year. The report will look like below structure in the application.
Product Subcomponent Total
P1 S1 10
P2 S2 4
P2 S21 15
Now i want to pick the value of Prouct and sub component for every row dynamiaclly and want to generate the URL with the conditions and make it as hyperlink for the Total Column.
Iam able to make hyperlink for the Total column using the edit options for the total attribute, but it is opening the same page for all the rows in the total column. I want to generate dynamic URL by picking the value prodcut and sub componenet dynamically from the report for every row and want to make it as hayperlink for every row individually.
Please tell me how to do this?
Please revert back if you are not clear. Appericiate for your quick help.

Hello <unknown user>,
So you already set the Column Link attributes for your Total column. Should all links go to the same page, but with different parameters (ProductID, SubcompID)? Or to another page? And how can you determine that page?
Assuming you'll go to a sort of detail page or form:
Target = [Page in this app]
Page = <your target page no>
Item1 = <ProductID field in target page>
Value = #PRODUCTID#
Item2 = <SubcompID field in target page>
Value = #SUNCOMPID#
(you can use the ' flashlight' for getting the correct values)

Problem in creating dynamic array field.

Hi there,
Following are the steps we followed to dynamically build the array field.
1) Single column array field created with a single widget in the design time.
2) Few more columns were added using 'Addcolumn' method.
3) Data in the array object mapped to the array field is populated.
4) All the dynamic field state was set to FS_UPDATE.
5) Used Updatefieldfromdata method in all levels ( window, compound field, field widget).
Problem faced
1) Data is not visible in the dynamic fields created. But the data is visible in the field created during design time.
Appreciate, if given any solution for this.
Regards,
Anand.

if you don't see your text, you're not embedding the font.
when you use actionscript to embed a font, you need to have the font in your library with a linkage id, create a textformat instance and assign its font property and finally assign the textformat to your textfield. for example
_root.createTextField("txt",_root.getNextHighestDepth(),50,50,50,50);
_root.txt.embedFonts=true;
_root.txt.text="hello";
_root.txt._rotation=20;
var tfor:TextFormat=new TextFormat();
tfor.font="yourfontslinkageid"; // <- linkage id of font in your library
_root.txt.setTextFormat(tfor);

How to mention numbers in array while creating dynamic sql

Hi,
I am creating a dynamic sql and in that I am selecting some rows from the table and storing it into the array.
I am firing this sql statement within trigger.
But i got the error:
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
I took the same sql statement (the one which was created dynamically) in the procedure and tried to run it but it gave me the same error.
=========================================================
Begin
type NewValueArray is table of varchar2(4000);
nVal_Array NewValueArray;
Begin
Select
DISCOVERYHOSTNAME,

nVal_Array(3)
from ALT_42_Consolidated
where rowid = 'AAEWNEABXAAAAkxAAA';
EXCEPTION
WHEN others THEN

End;
=========================================================
I tried using to_number but still the same error.
Can some body please inform me where I am goofing.
Thanks!

I got a different error, but you need to initialise your nval_array and make sure it can hold three values. The following should work:
declare
type NewValueArray is table of varchar2(4000);
nVal_Array NewValueArray := NewValueArray();
Begin
nval_array.extend(3);
Select col1, col2, col3
into nVal_Array(1), nVal_Array(2), nVal_Array(3)
from tab1
where rowid = 'AAAGJZAAGAAAAAWAAV';
EXCEPTION
WHEN others THEN
Raise;
End;

How do you create an array of clusters dynamically

I have created a cluster of 3 elements (string, I32, I32) dynamically then I want to create a 1D array of clusters dynamcally as well, but I am having trouble creating the array of clusters . If anybody has any suggestions please help. I will really appreciate it, Thank You

You are not building your array correctly. What you are doing is taking a single element array of data you just read and replacing it with an empty data set.
Look at the following ways of doing this. The one in the middle is only available in later versions of LV, but is supposed to handle memory more effeciently. But, both the top and middle basically do the same; I preallocate memory for the rows and columns, then replaces the element of the array with the current row and columns data. The output of the loop with have a 2-D array of all the data.
The bottom example does create an empty array before the loop runs and uses the indexing feature of the for loop to build the array for you. All gve you the same result as far as data in your array is concerned.

How to create dynamic Invoice report based on Tax calculations

Hi Ppl,
I have an invoice report requirement. There are multiple line items in invoice and each line item will have a tax % and discount associated with it. Discount has to be applied at line item level. Tax will be applicable on resultant amount which respect to tax share on total amount. Below is example
Part# Tax     Qty     UnitPrice Amount     Discount     Net Value
1     12.5%     40     10          400          100          300
2     12.5%     50     20          1000          200          800
3     4%     10     30          300          50          250
                         SubTotal                    1350
                         VAT 12.5% on 1100(300+800)     137.50
                         VAT 4% on 250               10
                         Total Amount               1497.5
I have created a static rtf which does all calculations correctly. I have hardcoded 12.5 and 4 % tax values for calculations. But issue is that taxes are changeable in future so I want to create dynamic template which takes care for tax calculations. I thought of to create an array to store distinct tax values from XML data and then to perform calculation but don’t know how to do that.
Can some body help me out as this is very critical and urgent?
Note: Tax calculation can be done at line item level itself but there are some scenarios where additional discounts are there so tax calculation can not be done at line item level.
Below is the sample XML data

How to create dynamic variable in Java?

Hi,
I want to create dynamic varible , using ArrayList or Vector. The number of array i dont knwo, so how to create dynamic ArrayList or Vector.
for example:
ArrayList1,ArrayList2,ArrayList3.....n
or
Vector1,Vector2,Vector3 .....n, the n value i will get at run time, so how to create the dynamic ArrayList or Vector or i can use any other Object in java,
Pls provide your input.
Sridhar

1. I have a HashMap with dataok ... fair enough.
2. depending on its size, i need to create variable
to store them.uhm ... why? If you have a variable number of elements in the map then you'd need to generate a variable number of variables (a number, that is not know at compile time, as it seems). Now if you could somehow create those variables, how would you access them? You'd have to generate the code handling them as well ...
Tell us what kind of data you've got and what you want to do with it. There's certainly a better solution to your problem.

How to create dynamic strcture and accepting runtime value in work area

Hi,
I am using RFC_READ_TABLE for joining more than table and written select query but into clause work area value is passed but it is short dump is displaying with too few many fields in into clause .work area WA need some casting type conversion which accepts the some run time value and should have some structure for it.how to create dynamic structure?

hi
good
go through this and use in your report accordingly.
If you are trying to read some information from SAP and you can't find the right BAPI then RFC_READ_TABLE can do the job for you.
RFC_READ_TABLE is powerful RFC it gives you the access to all tables and views in SAP. I basically used RFC_READ_TABLE for Material Master Search application on the Intranet.
Now you may say there are lots of BAPI for this functionality. You are right but I had to work around the BAPI to get Prices (Moving Average Price) and it just did not work very well. Because of the nature of the application I had to use RFC_READ_TABLE because then I can use powerful SQL expression for searching. RFC_READ_TABLE give you the ability to code the where clause which is quite enough.
I have included part of the code use in asp page to read ENT1027 for Mgroup and M description & number but without object creation. The other part of the code reads MBEW for price & quantity.

Creating dynamic sized arrays and filling them automatically on speedy 33

hi all,
I am trying to create dynamic sized arrays on Speedy-33. Specifically, depending on the user input, I want to be able to create
arrays with 128 or 256 elements and fill them automatically. However,
array constant element is fixed for Speedy 33; thus I have to manually set the
size of the array with the mouse and enter the values in to the array by
myself. I want to make this tedious process automatic. Would this be possible? thanks so much for comments!

Casiopea,
There is a really great article on using arrays with LabVIEW DSC which can be found here:
How Can I Be Successful With Arrays In the LabVIEW DSP Module?
One of the biggest things that should be noted about DSP is that there is no dynamic memory allocation. Your array size must be fixed, and thus, your array needs to be initialized by using a constant.
An easy way to initialize an array constant that has many elements that are all the same is to simply create a numeric constant that has the value that you want. Then, create a new blank array constant and drag the numeric into it. In the index input for the array constant, type in the index of the last element that you want to be initialized. Then type in the value in the element that is displayed and all of the elements before it will be initialized to the default value of the numeric constant that you dropped into the array constant. I hope this helps. I would really recommend reading through that article, as it has a lot of great information about using arrays with DSC.

Creating a dynamic array in Actionscript

I am wondering how I would create a dynamic array in Acionscript, i.e. one that utilizes fields for mapping data like this:
public var SMITH:Array = [
           {date:"29-Aug-05", close:45.87, profit:52},
           {date:"23-Aug-05", close:45.74, profit:32},
           {date:"21-Aug-05", close:45.77, profit:22},
           {date:"25-Aug-05", close:46.06, profit:51},
but where you would just be reading in data without knowing what your data looks like. In other words, I'd like to take something like a database table with X number of columns and have Actionsctipt map each row to an item in my array. Something like this:
for each row in table
add {col1:value, col2:value, col3:value, ... colX:value} to Array
So I won't know "date" or "close" or whatever at runtime, I'll just have X number of items for each element in the array. How would this be done?
The reason I need this mapping feature is because I then want to map the table-like array as the data provider to charts, datagrids, etc.
Thanks.

How to build an ActionForm that have "dynamic" array as its property?

Hi...
In my current project i need to create an ActionForm that has a property (array, list, or something else) that can take any number of element (dynamically).
The JSP is generated by other pageFlow (contains a dynamic rows of input), so the ActionForm must be able to take any number of input rows.
Any suggestion how to make such ActionForm?
I tried to create an actionform like in Struts (indexed property) but seemed not to work:
public List objectInputs;
public Object getObjectInput(int key)
if (objectInputs== null)
objectInputs= new ArrayList();
return objectInputs.get(key);
public void setObjectInput(int key, Object objectInput)
if (objectInputs== null)
objectInputs= new ArrayList();
this.objectInputs.set(key,objectInput);
Thx in advance :)

How do you create an array without using a shell on the FP?

I want to be able to read the status of front panel controls (value, control box selection, etc.) and save it to a file, as a "configuration" file -- then be able to load it and have all the controls set to the same states as were saved in the file. I was thinking an array would be a way to do this, as I have done that in VB. (Saving it as a text file, then reading lines back into the array when the file is read and point the control(s) values/states to the corresponding array element.
So how do I create an array of X dimensions without using a shell on the front panel? Or can someone suggest a better way to accomplish what I am after? (Datalogging doesn't allow for saving the status by a filename, so I
do not want to go that route.)

Thanks so much m3nth! This definitely looks like what I was wanting... just not really knowing how to get there.
I'm not sure I follow all the icons. Is that an array (top left with 0 constant) in the top example? And if so, that gets back to part of my original question of how to create an array without using a shell on the FP. Do I follow your diagram correctly?
If I seem a tad green... well I am.
I hope you understand the LabVIEW environment and icons are still very new to me.
Also, I had a response from an NI app. engineer about this problem. He sent me a couple of VI's that he threw together approaching this by using Keys. (I still think you are pointing to the best solution.) I assume he wouldn't mind m
e posting his reply and the VI's for the sake of a good, thorough, Roundtable discussion. So here are his comments with VI's attached:
"I was implementing this exact functionality this morning for an application I'm working on. I only have five controls I want to save, but they are all of different data types. I simply wrote a key for each control, and read back that key on initialization. I simply passed in property node values to the save VI at the end, and passed the values out to property nodes at
the beginning. I've attached my initialize and save VI's for you to view. If you have so many controls that this would not be feasible, you may want to look into clustering the controls and saving the cluster as a datalog file.

How do I create an array with variables also splits words in a txtfile?

Hello guys,
I made a script that reads a text file.
function readMyFile()
var myFile=File(app.activeDocument.filePath + "/LareLog.txt");
if (myFile.exists)
        myFile.open("r");
        var Temps = myFile.read();
        alert (Temps);                          // message the content
        var nyRad=("\n");                    // break the line
        textArr=Temps.split(nyRad);
        alert(textArr);                          // message the content with all info on new lines ("\n");
        myFile.close();
my textfile contains:
~/Desktop/3.indd ,Thu Mar 20, 2014, 11:26:34 , GMT+0100
I wonder how do I sort the content in array
in this order, also creates variables for each string.
var= string 1[~/Desktop/3.indd]
var2=string 2[11:26:34]
var3=string 3[11:26:34]
var4=string 4[2014]
var5=string 5 [GMT+0100]
Thank you in advance people.

Hmmh?
Jump_Over said it before: „… are stored as separate array's elements …“ in your [textArr]
So you can create now variables on this way:
var string_1 = textArr[0]; // and so on
alert(string_1);
See Java Scripting reference for more examples how to use Arrays.
