Using arrays in LV NXTToolkit

I've written a post regarding problems with array usage with (version 1.0)
LabView compiler (i.e. what is currently used in NXTToolkit and NXT-G).
Read it here:

Thanks for your info, clear and crispy and indeed completely counter intuitive for everybody who is used to LabVIEW programming

Help using arrays in java

HI all,
I am working on a program that will print out my initials 'A' and 'T' using arrays. I am asked to initialize the first intial to '*' and the second intial to '@'. I wrote the code but the output is wrong. Can someone help me by letting me know what I am doing wrong in my arrray?I just get back my array of 30X30. I also wrote a driver but when I run the program, I really appreciate it so much.
public class Initial
 private char whichinitial ;
 private int MAX =30;//Maximum amount for 2-d Matrix
 char[][] letterMatrix = new char[MAX][MAX];//2-d Array 30 x30
 private boolean first = true;
 public Initial()
 { //FIlls Array full of '*'s
 whichinitial = '*';
 for(int i=0;i< MAX;i++)
 for(int j=0;i< MAX;i++)
 letterMatrix[i][j] = whichinitial;
 public void setLetter(char letter)
 {//Setter for Letter
 whichinitial = letter;
 public char getLetter()
 {//Getter for Letter
 return whichinitial;
 public void firstLetter()
 { //Creates an A shape
 for(int i=0;i< MAX;i++)
 for(int j=0;j< MAX;j++)
 if((i>0)|| ((i<6) || ((j>0) && (j<29))))
 letterMatrix[j] =whichinitial;
 public void secondLetter()
 {//Creates an T shape
 first = false;
 for(int i=0;i <MAX;i++)
 for(int j=0;j <MAX;j++)
 if((i>1) ||(j < 29)||(j>5)||(i>10))
 letterMatrix[i][j] = whichinitial;
 public void display()
 {//Displays the Initials
 if(first)
 System.out.println("\n \n \n My First Initial," + whichinitial + ", follows:");
 else
 System.out.println("\n \n \n My Last Initial," + whichinitial + ", follows:");
 for(int i=0;i <MAX;i++)
 System.out.println();
 for(int j=0;j <MAX;j++)
 if(letterMatrix[i][j] == '*')
 System.out.print(" ");
 else
 System.out.print(letterMatrix[i][j]);

I am trying to write a program using a matrix. The size of the maxtrix should be 30X30. The first initial shoulld be initialized to '*' and the secind initial should be initialized to '@'. Both initials should be 30 characters high and 30 characters wide and the initials should also represent the uppercase letter of your initials. I know that the first initial's matrix needs to be filled up vertically and the second initial needs to be filled horizontally but the output is wrong....PLease Help!

Using arrays in a jsf page

Hi guys,
I'm developing an ADF application in JDev 11.1.1.6.0. I have problem about using arrays in jsp page. I have an iterator that brings me data from UCM. I just want to take every documents seperately and use in a Jquery division by division.
Can i have chance to use an array tag in that page? Or how can i make it possible my work in a different way?
Thank you so much,
Erdo

Hi Frank,
I've already use an iterator. I just want to take datas and after close the af:iterator tag. Then i will use those datas in a different block.
My code :
<af:iterator var="node" value="#{nodes}" id="i1">
<af:outputText value="#{node.propertyMap['CSGMNEWS_REGDEF:Desc'].asTextHtml}"
id="ot1"/>
</af:iterator>
I want to take all informations from node.PropertyMap[] and then i will set the values of outputText with those informations. I hope I'm clear.
Regards,
Erdo

Using arrays in apex

hi i want to know if some can guide me how to use array in apex.
i have a tabuler report with 4 columns.
i need to write a validation in the tabuler report for that i need to used array.
can I directly access the colums as i have shown below? or do i need to decleare this arrays some were in apex?
e.g
FOR i IN 1 .. ow_app.g_f01.COUNT
loop.........................
LOGIC
end loop;
from what i understand i can access each column as ow_app.g_f01,ow_app.g_f02,ow_app.g_f03,ow_app.g_f04 does this make sense?
thanks a lot.

Hi user591315 (please tell us your name - we're a friendly group!),
In answer to this and your previous related post, there is an excellent example of what you're looking to accomplish provided by Denes Kubicek available at http://apex.oracle.com/pls/otn/f?p=31517:41

Using Arrays in a program

First, I would like to thank everyone in this forum for all the help they have given me over the past few weeks. With that said, I am currently trying to alter the following code to accept and use arrays to end to produce three seperate results. The program now as three hard coded variables which are
Amount = 200000.00;
Term = 30;
InterestRate = .0575;
I need to have the program work the same, but produce results for three different Terms and Three different periods. Below is the code the I am working on, I have added two arrays containing the required information. I am having a hard time coming up with a for statment to move the program through the two arrays. Any pushes in the right direction would be great. I left the hard code variable in place, I know that I do need to remove them and alter the equations. I just thought it would be easier for everyone to understand if I left the code in working form.

Using arrays in forms

Hi All!
Anybody know how to use Arrays in Forms 6?

   mytab TYP_NUM_ARRAY ;
Begin
   For i IN 1..10 Loop
      mytab(i) := i ;

Using arrays in JAVA

Hi Guys,
I always had a few problems using arrays and now I need to use them and I am stuck.
on my program i need to create an array of int with the numbers 1 to 1000 in it for this I have done:
int[ ] array;
on the class constructor
array = new int[1000];
to fill the array:
for (int i = 0; i < array.length; i++)
 array[i] = i;
The problem is that I always get an ArrayIndexOutOfBoundsException error.
I know how to solve it which is to create an array with 1001 elements but is there a more elegant way of creating the array or this is the way to do it?
To put my question in another way if any of you Guys was creating this program which way would you do it.
Best regards
 Luis

Sloppy of me. This is a bit better:
package cruft;
import java.util.Arrays;
* A class for a one-based array of ints.
public class OneBasedIntArray
 private int [] values;
 public static void main(String[] args)
 int [] values = new int[args.length];
 for (int i = 0; i < args.length; i++)
 values[i] = Integer.parseInt(args);
OneBasedIntArray intArray = new OneBasedIntArray(values);
System.out.println(intArray);
public OneBasedIntArray(int[] values)
this.values = new int[values.length];
System.arraycopy(values, 0, this.values, 0, values.length);
public int getValue(int index)
if (index <= 0)
throw new IllegalArgumentException("this array is one-based");
return values[index-1];
public void setValue(int index, int value)
if (index <= 0)
throw new IllegalArgumentException("this array is one-based");
this.values[index-1] = value;
public boolean equals(Object o)
if (this == o)
return true;
if (o == null || getClass() != o.getClass())
return false;
OneBasedIntArray intArray = (OneBasedIntArray) o;
if (!Arrays.equals(values, intArray.values))
return false;
return true;
public int hashCode()
return (values != null ? Arrays.hashCode(values) : 0);
public String toString()
StringBuilder builder = new StringBuilder();
builder.append("OneBasedIntArray{");
for (int i = 0; i < values.length; i++)
builder.append("(").append(i+1).append(",").append(values[i]).append(")");
builder.append('}');
return builder.toString();

Using Arrays in SELECT BULK queries

Dear All,
Can we use arrays in the SELECT Bulk operations.
Example:
SELECT empno BULK COLLECT INTO v_empno FROM EMP WHERE deptno = v_deptno(m);
Is there any way we can simulate this example.
Appreciate your response on this one.
Thanks,
Madhu K.

Yes you can. See the example.

Error using Arrays.toString()

Hi there,
I am getting the following error using Arrays.toString on a String Array. 'toString() in java.lang.Object cannot be applied to (java.lang.String[]).
The line in question is at the bottom of the below code. It starts 'rtitem.appendText.....

No, that doesn't make any sense. Arrays.toString can take any array as an arg: [http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#toString(java.lang.Object[])]
import java.util.*;
public class A {
public static void main(String[] args) {
 String str = Arrays.toString(args);
 System.out.println(str);
:; java -cp . A abc 123 xxx
[abc, 123, xxx]

Can i use array.count in line?

All,
I have one small oracle program that take a ',' separated string as an input
and assigns the individual string to a nested table.
I am wondering if I can directly use array.count in my sql below
instead of assigning the count of the array 1st and then
using it.
l_cause_codes_array := util_pkg.tokenize_string(p_cause_codes_csv, ',');
l_count := l_cause_codes_array.count;
My current sql:
delete from po_complaint_cause p
where p.po_number = p_po_number
and p.comp_code = p_comp_code
and l_count > 1;
I would like to do something like:
delete from po_complaint_cause p
where p.po_number = p_po_number
and p.comp_code = p_comp_code
and l_l_cause_codes_array.count> 1;
I just want to reduce one context switch if possible.
Thanks.

Hi,
did it give an error? Did you try? But it is possible.
But why not the next code:
l_cause_codes_array := util_pkg.tokenize_string(p_cause_codes_csv, ',');
if l_cause_codes_array.count >1
then
    delete from po_complaint_cause p
    where p.po_number = p_po_number
    and p.comp_code = p_comp_code
end if;Do only the delete if it is bigger than 1, that is I think the fastest switch.

How to use array of Point Class

I use Point class as array. I already create that. However I can't access to setLocation.
Ex.
Point myPoint[] = new Point[10];
myPoint[0].setLocation(10, 2);
It has a error.
Please Explain me.

That doesn't do what you think it does, unless you want your array to contain 10 references to the same Point object.The OP has received a good answer, I believe. So it's worth risking diverting this thread into the weeds by pointing out that if Java had closures then BalusC's code could be modified to work.

How to use Array in Formcalc?

Please share syntax for using Array in Formcalc.

Hi,
FormCalc is a simple scripting language and does not support objects like arrays.
The only function that come close to an array in JavaScript is Choose(),
This first parameter selects the nth value of the following comma separated strings.
Choose(3, "String1", "String2", "String3", "String4")
returns String3

For information on the ARRAY command, check out <a target=_blank class=ftalternatingbarlinklarge href="http://dev.hyperion.com/techdocs/essbase/essbase_712/Docs/techref/techref.htm">this hyperlink</a>. Click on Calculation Commands, then choose ARRAY. Can you give me some information explaining why you want to use ARRAY?

Using array binding to perform multiple rowupdates in one pass

For the first time I am attempting to use array binding in VB.NET to update multiple rows via a single execution of a stored procedure. My subroutine is:
Friend Sub UpdateSolutionStatusUsingArrays(ByVal intNumBeingUpdated As Integer, ByVal arrScenarioID() As Integer, ByVal arrSolutionID() As Integer, ByVal arrInOrOut() As Integer, ByVal arrTimePeriod() As Integer)
Try
'Set up the Command object
Dim cmdUpdateSolutionStatus As OracleCommand
cmdUpdateSolutionStatus = New OracleCommand
cmdUpdateSolutionStatus.CommandType = CommandType.StoredProcedure
cmdUpdateSolutionStatus.CommandText = "ProcUpdateSolutionStatus"
cmdUpdateSolutionStatus.Connection = cnnORACLE
cmdUpdateSolutionStatus.ArrayBindCount = intNumBeingUpdated - 1
cmdUpdateSolutionStatus.CommandTimeout = CInt(tblOptions.Rows(intDatabaseIndex).Item("ConnectionTimeout"))
'Add ScenarioID array as parameter
Dim p_ScenarioID As New OracleParameter("ScenarioID", OracleDbType.Int32)
p_ScenarioID.Direction = ParameterDirection.Input
p_ScenarioID.Value = arrScenarioID
cmdUpdateSolutionStatus.Parameters.Add(p_ScenarioID)
'Add SolutionID array as parameter
Dim p_SolutionID As New OracleParameter("SolutionID", OracleDbType.Int32)
p_SolutionID.Direction = ParameterDirection.Input
p_SolutionID.Value = arrSolutionID
cmdUpdateSolutionStatus.Parameters.Add(p_SolutionID)
'Add InOrOut array as parameter
Dim p_InOrOut As New OracleParameter("InOrOut", OracleDbType.Int32)
p_InOrOut.Direction = ParameterDirection.Input
p_InOrOut.Value = arrInOrOut
cmdUpdateSolutionStatus.Parameters.Add(p_InOrOut)
'Add TimePeriod array as parameter
Dim p_TimePeriod As New OracleParameter("TimePeriod", OracleDbType.Int32)
p_TimePeriod.Direction = ParameterDirection.Input
p_TimePeriod.Value = arrTimePeriod
cmdUpdateSolutionStatus.Parameters.Add(p_TimePeriod)
'Open connection
cnnORACLE.Open()
'Run stored procedure
cmdUpdateSolutionStatus.ExecuteNonQuery()
'Tidy up
cmdUpdateSolutionStatus = Nothing
cnnORACLE.Close()
Catch ex As Exception
WriteLog("Subroutine UpdateSolutionStatusUsingArrays:" & ex.Message.ToString)
strState = "Error"
'Update Run Status to show error has occurred
cnnORACLE.Close()
UpdateRunStatusORACLE(7)
End Try
End Sub
When the routine tries to run cmdUpdateSolutionStatus.ExecuteNonQuery() I get the error message:
Unable to cast object of type 'System.Int32[]' to type 'System.IConvertible'.
I have tried all sorts of variants of the code but with no success. The arrays are being set up correctly. Anyoneone know what I'm missing?

Try declaring the arrays as OracleNumber datatype instead of Integer. I've had this issue before, and I believe this is what I did to solve the problem.

Using Arrays.asList: Is Array[x] == List.get(x)

I have an Object[] Array and I wish to remove index 'x' from that Object[] Array. If I use Arrays.asList() passing in the existing Object[] Array I will get new List Object containing the objects from the Object[] Array. Is it guaranteed that index 'x' from the Object[] Array is the same Object from the index 'x' in the new List?
Object[] obj = new String[] {"obj_0", "obj_1", "obj_2", "obj_3"};
List list = Arrays.asList(obj);
assertTrue(obj[0] == list.get(0));
assertTrue(obj[1] == list.get(1));
assertTrue(obj[2] == list.get(2));
assertTrue(obj[3] == list.get(3));Are the above assertions always guaranteed to be true?

Jared_java_dev wrote:
I thought the JavaDoc API would state it as well. I did originally check that.
I agree that it should keep the order but I wanted to verify this behavior. It would make some coding logic much more simple.
Objective is to remove ojb[2]
String[] obj = new String[] {"obj_0", "obj_1", "obj_2", "obj_
//Perferred logic
List<String> list = Arrays.asList(obj);
//remove unwanted element
list.remove(2);
//create new Object[] without unwanted element
obj = (String[]) list.toArray();
{code}
as opposed to
{code}
String[] obj = new String[] {"obj_0", "obj_1", "obj_2", "obj_
//unwanted logic
List<String> list = Arrays.asList(obj);
for (int x = 0; x < obj.length; x++) {
// == or String.equals
if (list.get(x) == (obj[x])) {
list.remove(x);
obj = (String[]) list.toArray();I guess that I could write a sample program and run to verify this .
Thanks for everyone's input.No, you won't be able to simply 'delete' items from this array-backed list. It is a fixed size list, so additions/deletions are expected to throw exceptions.
So now my question is: Why is the master an array in the first place? Seems like it should be a List from the get-go.
