How to declare an array

Hi ,
how do i actually declare an array of size 10 ? but i do not want to initialise the size which i will get after some processing
String Array[];
int arrysize ;
arrysize = Getsize();
so how to declare the size here
pls help
tks & rdgs

how do i actually declare an array of size 10 ? but
t i do not want to initialise the size which i will
get after some processingWhat a strange question. How do you know that after some processing the size will be exactly 10? If you know then why not make it 10 right from the start?
What you need probably is a dynamic array. That's an array that can grow to fit your needs. Java has one and it's called ArrayList. Check it out.

then always use String and don't consider
StringBuffer at the outset. 'best practices' need not
be seen as premature optimization. besides, if it is
abstracted, does not matter how it is stored
internallyNot sure I would agree with this example - a String is immutable, if I want to change the object then using a StringBuffer makes sense (conveys the intend, yada, yada, yada).
Although, I do agree with you that some optimizations are best practices and should be used. I also come from the old days when optimization was always on our mind. Also, I would not expect someone to do something like re-calculate a value every time it is needed instead of storing the value in a variable, just to avoid optimization.
I just think that the example of using a 1-dimensional array when a 2-dimentional array is a better representaion of the "real world" will both obscure the intention and compicate the code.

How to Declare Arrays in bpel and use them as acollection

Hi,
I Am new to Bpel, I had created an empty Bpel Process and configured file adapter to a directory, In my text file i have 3 records with four columns, each column seperated by ',' and each record seperated by "EOL(end of line)", Below is the xsd file generated by the native format xsd builder, taken a recieve activity to recieve the contents of file from file adapter.
So all the data which is in the file will be there in recieve activity.
FileContents
55555,rgfdgsd,gfdgfdg,23
66666,retretret,trtertg,21
77777,rtrttreter,trtter,23
My Question is
I want to compare whether value of C1 = '55555' and if the value is equal to 55555 then that record with c1=55555 has to be inserted into database by using Arrays
How to compare the value of c1 through bpel functions.
with java i have to use the logic similar to this by using Xpath
getElement by tagname(c1);- it will give all the elements with tagname c1, three records are there with tagname c1 (c1=55555,c1=66666,c1=77777), we have to iterate through the elemnts and check whether the value iof c1='55555' and get the whole parent block which contains values of c1,c2,c3,c4 and insert that to database
What variables we have to use to get the Similar logic in bpel

I think it is a good option to use transformations. Do you have any critical reason why you want to do this using array?
Little explanation below for your questions.
As per my understanding from variable is the recieve activity variable and to variable is the Array variable is it right?
Yes. Here I was try to build my array from the different source system data. This will append data to the array variable.
How can we declare an array variable in bpel(to variable) with name as Variable_Array, part as payload and query as ArrayList?
*Any element that can hold another element can be a array.
For example if element A is declared as sequence of element B type, then A acts as a array for B*
Could you please explain this also, what is from variable? and what is to variable?
+<assign name="Assign_XPath_For_Array">+
+<copy><from expression="concat('/ns1:ArrayList/ns2:ArrayElem') "/><to variable="Variable_Xpath"/></copy>+
+</assign>+
what is the type of to variable "Variable_Xpath"(String or int etc)?
This creates a dynamic Xpath and store in some variable here. Here the variable is called Variable_Xpath which is a string
similarly what is the type of to variable?
+<assign name="Assign_Read_Array">+
+<copy>+
+<from expression="bpws:getVariableData('Variable_Array','payload',bpws:getVariableData('Variable_Xpath'))"/>+
+<to variable="Variable_Read_Array_Element" query="/ns1: ABC"/>+
+</copy>+
+</assign>+
To variable type is the variable that I read from the Array.
*For example if A is the array holding B, then the to variable is B and from is doing A[counter]*

How to declare a dynamic array in java

I have to use a dynmic array of boolean and the size of this array will defiend throuh the run of the program to explian
boolean[][] a;
a=new boolean[number_of_ raw][number_of_ culm];
after the program run the number_of_ raw and number_of_ culm will defind..so if any body know how to declare this kind of arraies in java please help me.

My previous post gives me an idea on how to use ArrayList of ArrayList as dynamic 2 dimensional array.
More info bellow
ArrayList rows = new ArrayList()
ArrayList columns_of_row0 = new ArrayList()
rows.insertAt(0) = columns_of_row0;
ArrayList columns_of_row1 = new ArrayList()
rows.insertAt(1) = columns_of_row1;and so on..
You can't use the code exactly or similar way, it would depend on how this array grows in your application.
But this and my previous post should give an idea on how to insert and retrieve elements from ArrayList when
treated as 2 dimensional array.
Hope this helps.

How to declare arrays?

Hi!!
I have one doubt.
I need to declare one array with array size 10 , datatype string
And with this i need to specify that the maximum length of each string should be 20.
So is it String [10,20]
i saw this in one book
is this correct, if not can you tell me how to do this
thanking you !!!

So in a declaration string [][] we cant set the
length of the string we are gonna insert in each
space of array??No because using String[][] declares a two dimensional array (more correctly: an array of arrays) of Strings. Each String can still be as long as the maximum length of a string (theoretically Integer.MAX_VALUE characters).

How to declare and initialize a STRING ARRAY (assign strings to array elements)

How to declare and initialize a STRING ARRAY (assign desired strings to elements of an array, for example "abc", "def", "ghi", "jkl", etc.) in LabVIEW? I saw a "string array" block in help, but could not find it in the function palette. Does a spreadsheet string have to be in a file (or can it be in a string constant block)? Thank you.

Hi,
you can do it in several ways:
1. Direct way: Create string array control on front panel and type strings in its elements
2. Programmatically 1: Create string array indicator (or local variable of control), right click on it in block diagram, select "Create constant" from drop down menu. The array constant will appear. Now type values in this constant's strings
3. Programmatically 1: Use "Build array", "Replace array subset", "Insert into array" or "Initialize array" functions from "Functions->Array" palette.
And of course you can combine all of these methods.
Good luck.

How to declare value binding to array list element in a pojo?

I have a POJO called P, that contains an ArrayList member called w.
class P {
private ArrayList w = new ArrayList(5);
w is initied in the class constructor.
The POJO is in the SessionBean and I would like to reference individual
elements in the ArrayList via a value binding like so;
#{SessionBean1.instanceOfP.w[5]}
I'm not sure how to declare the getter/setter for member W in POJO P
so that setter and getter injection work.

You may not be able to directly set the indexed value.
Try some thing like this.
Add a property that returns the indexed value.
Ex. if you ArrayList objets are of type "String"
int index = 5;
public String getMyValue(){
return w.get[index]
Now your value binding would look something like
#{SessionBean1.myValue}
BTW, if you want to access different index, create another method
public void setIndex(int index){
this.index = index;

[Bash] How to `declare` a global variable inside a function?

#!/bin/bash
# Not using declare -A, array will be treated as indexed array rather than an associative array
seta()
for ((n=0;n<$1;n++)); do
printf -v a_$n[k] %s k$n
printf -v a_$n[j] %s j$n
eval echo inside seta: a_$n[k] = \$\{a_$n\[k\]\}
done
seta 3
echo outside: a_0[k] = ${a_0[k]}
echo outside: a_0[j] = ${a_0[j]}
echo
# Use declare -A inside function, array will be undefined outside
setb()
for ((n=0;n<$1;n++)); do
declare -A b_$n # Note here
printf -v b_$n[k] %s k$n
printf -v b_$n[j] %s j$n
eval echo inside setb: b_$n[k] = \$\{b_$n\[k\]\}
done
setb 3
echo outside: b_0[k] = ${b_0[k]}
echo outside: b_0[j] = ${b_0[j]}
echo
# The bad solution, only works if we know beforehand how many c_? arrays will be assigned inside setc()
for ((n=0;n<3;n++)); do
declare -A c_$n
done
setc()
for ((n=0;n<$1;n++)); do
printf -v c_$n[k] %s k$n
printf -v c_$n[j] %s j$n
eval echo inside setc: c_$n[k] = \$\{c_$n\[k\]\}
done
setc 3
echo outside: c_0[k] = ${c_0[k]}
echo outside: c_0[j] = ${c_0[j]}
My original code does the declare -A as in setb(). I was surprised when I saw all blank output... Now the problem is illustrated clearly by the setb() example.
The setc() example works, but a bit ugly: look at the two 3's...
My ideal solution would be, something like `declare_global -A b_$n` in setb()
Any ideas?

with current bash versions, i don't think it is possible to declare global associative arrays in functions.
what you are after is the "-g" option of typeset which is available in zsh.
i think i read somewhere that something similar may be planned for bash 4.2.

How to create an array?

I know that when you create a new BPM object attribute you can choose an array in 10g. However, that just declares the array; I'm wondering how to allocate memory to it. I want to use it in a .jsp page for a list of fields. Also, what tag would I use to pass the parameters? i.e '<f: fieldName att="BPMObject.attribute"/>' is used for normal string variable attributes, what would I use for an array?

Hi,
Here is the code that you can write in your jsp page to iterate over an array.
     <c:forEach var="test" items="${bpmObject.bpmArray}" begin="0" varStatus="status" >
          <tr>
          <td align="center" width="25%">
          <c:out value="${test.arrayAttr1}"/></font></td>
          <td align="center" width="20%"><font size="2" face="arial">
          <c:out value="${test.arrayAttr2}"/></font></td>
          </tr>
     </c:forEach>

Rookie Question: Swap values? Declare an array and values of its indices?

Hello,
I hope this is the right forum: I have a simple Java Problem but i do not get it.
Is like that: I have to swap values within an array e.g i have one array with 3 indices. Indice 0 (the first indice) has value 12. The middle indice has no value, and the second indice has value 9. How to swap 9 to 12 and 12 to 9 without direct swap, in other words, by using the middle indice that has no value or is zero? And how do i write it in an array?
My other questions: How do i Declare an array and values of its indices?
I hope this is the right forum or site at all, in cas enot, i hope you still can help or give me links that could help. I really need this.

Hi Rookie,
     http://forum.sun.com is the best place to get answers for your queries.
     Answer to you first question:
     array[0]=array[0]+array[2]; // array[0] will have 21, because 9+12.
     array[2]=array[0]-array[2]; // array[2] will have 9, because 21-12.
     array[0]=array0]-array[2]; // array[0] will have 12, because 21-9.
     Hope your first query is resolved.
     I will answer your next query in my next reply.
Thanks & Regards,

How to pass int array as an IN parameter to PLSQL Procedure

Hi,
How to pass int array in java to a stored procedure througn jdbc
and what type of data type I should declare to this IN parameter
in PLSQL Procedure.
Thanks,
Simi

Hi,
The best way to do what you want depends on what you want. Start by describing what you need to do. It's best to post some sample data (CREATE TABLE and INSERT statments) and what results you want from that sample data. (See the forum FAQ: https://forums.oracle.com/message/9362002)
If you have ideas about how to do the job (e.g., populating a temporary table) it can be helpful to include those, too, but distinguish clearly between WHAT you need to do and HOW you might do it.
As Bencol suggested, a SYS_REFCURSOR might be the best way to pass back the results.
Since you didn't post your table, or even describe what you wanted to do with it, I'll illustrate using scott.emp, which is probably on your system.
Say you wanted a procedure that took a DATE as an argument, and returned a some designated columns (empno, ename and hiredate in the example below) for all employees hired on or after the given DATE. You might write a procedure like this:
CREATE OR REPLACE PROCEDURE hired_since
(   start_date IN   DATE
,   out_data    OUT SYS_REFCURSOR
AS
BEGIN
    OPEN out_data FOR
        SELECT empno, ename, hiredate
        FROM    scott.emp
        WHERE   hiredate >= start_date;
END hired_since;
SHOW ERRORS
You can test it in SQL*Plus like this:
VARIABLE   c REFCURSOR
EXEC hired_since (DATE '1982-01-01', :c);
PRINT :c
The output I got from this test was:
     EMPNO ENAME      HIREDATE
      7788 SCOTT      19-APR-87
      7876 ADAMS      23-MAY-87
      7934 MILLER     23-JAN-82
