Remove element from array
hi
if i have an array
eg
int[] array = {4,2,1,2,1};
how to i remove the index 2 from it and create a new array?
thanks
You can't remove the element--an array's size is fixed at creation.
If you want a new array, create a new one that's one element smaller, then use System.arrayCopy to copy the elements you want to keep.

Strange problem with removing element from node
Hi,
I have a problem when I removed elements from a node.
here is the code:
String text = "123456";
IANode nodeA= wdContext.nodeA();
wdContext.nodeB().invalidate();
IBNode nodeB = wdContext.nodeB();
for(int i=0; i<nodeA.size(); i++)
IAElement e = nodeA.getEt_Emp_RespElementAt(i);
if (e.getID().compareTo(text)!= 0)
nodeB.removeElement(e);
else
wdComponentAPI.getMessageManager().reportSuccess(e.getID() + " was not removed");
The node A does have a row with field "ID" equals to 123456.
When running the application, it does write that "123456" was not removed...but it removes it....In fact my table is now empty.
How is it possible if it didn't perform the remove operation for ID = 123456 ?
Thanks in advance.David,
Because you are iterating node in wrong direction: see my reply to your post Re: Loop problem (seems that you assigns me 2 points without reading reply, and mark it as solved just because you stop solving it
So, in example in this thread, you must iterate node B in reverse direction, get element from B and remove it from B if it has some specific ID.

Emergency!! How to remove elements from a set? or..?
How do I remove elements from a Set?
If I have Set s1and s2, I want to create a new set which consist of all elements in s1 but not in the s2.
Which means, I have to s1.union(s2) and then remove elements of s2.
Is there any method which has this function (remove elment from a set)?
Or is there any other better way to solve this (which doesn't have to remove anything)?
If not, how to design a method which will do this job?
Your help will be very much appreciated.Hi
you can use method removeAll() from set
s1.removeAll(s2);
so s1 contains all the element not in s2.
If you want to lef s1 unmodifyed you have to create a copy.
Set s3 = s1.clone();
s3.ramoveAll(s2);
bye

Is there a way to remove elements from an array 1 by 1?
I have an two arrays, and they vary in size depending on a parameter set by the user (both arrays are the same size though, they both can vary in length). What I need to do, is remove elements one by one from the array, and use these as indices for another array. Basically, I built two arrays to store x-values on a graph. At the first value on the first array, I want y values on the graph to move from 0 to Y (any value). Then on the first value on the second array, I want the y values to move back from Y to 0 (creating a pulse, essentially, from the first value on the first array and the first value on the second array). By having each x value act as an indice for the y array, I belive I can acc
omplish this (ie, y =0 up to indice 90, then y = 5, then at indice 100, y goes back to equaling 0). I know this is poorly phrased, but it's difficult to explain. If anyone could help me out, I'd really appreciate it.jdaltonnal,
Note: to add an attachment based on your comment of 6/12/01 to my earlier reply, I had to go back to this 'answer' mode, which gives me the option of adding attachments.
Per your comment, you have a sequence, so I've added a simple sequence structure and the 2nd array to provide a 250ms delay between each array output. Let me know...Doug

Remove element from arraylist, jstl
HI there,
i use bean for an array list
<jsp:useBean id="list" scope="page" class="java.util.ArrayList"/>
then i add element in the list
later i need set up a loop does the following:
remove one element from the list and process it
until the list is empty
is this (romoving elment from a list) possible to be done using only jstl
thanksNo, it is not possible.
JSTL is for use on JSP pages.
JSP pages are meant for "display"
You sound like you are doing processing - this sort of stuff more properly belongs in a java class. -
Deactivate "insert element before / remove element" in array
Hello guys.
It is possible to deacitvate "insert element before / remove element" function appears after right-click on a array in the frontpanel?
"Description and Tip" should stay.
Thank you.
Alex
Solved!
Go to Solution.You can customize the right-click shortcut menu to remove some application items and keep others:
Right-click on the array (and not on the array element!) in the front panel and select Advanced->Run-Time Shortcut Menu->Edit...
This brings up the Shortcut Menu Editor:
Change the drop-down control from "Default" to "Custom".
Select the "???" line in the tree control on the left.
on the right, change the Item Type from "User Item" to "Application Item -> Description and Tip..."
It will automatically fill in the corrent Name and Tag.
Save the rtm either into its own file or into the control.
LV will automatically handle application items in the control, no event case needed.
I sometimes find the "Copy entire menu" function of the shortcut menu pretty useful if I only want to disable a few items.

I am trying to remove an element from a Vector and using the ff code:
Vector abc = getVector();
int index = 0;
abc.removeElementAt(index);
The element is not being removed, when i go back to check the number
of elements in the vector, it is still the same.
Please give me any ideas to make this work.Try this,
Vector abc = getVector();
int index = 0;
System.out.println("Size before : "+abc.size());
abc.remove(index);
System.out.println("Size after : "+abc.size());
What is the o/p?

Problems selecting elements from arrays
I'm having difficulty selecting indexed elements from a array of nodes. I have seen this issues discussed in a number of threads but none address the specific issue which I have encountered.
Previously in version 10.1.2 I constructed a XPath query and then used the BPEL getVariableData function to obtain the element I was after but this doesn't appear to be supported the same way in 10.1.3.1.
I'm using the following expression
bpws:getVariableData('VariableDBResult',bpws:getVariableData('xpath'))
and when I try to compile I get the following error
Error(243):
[Error ORABPEL-10085]: invalid argument
[Description]: in line 243 of "C:\....", the second argument "bpws:getVariableData("xpath")" for getVariableData is not a literal expression.
[Potential fix]: Please correct the second argument, you might need to escape using single quote or " to make it literal.
I used the same code in 10.1.2 and it compiled fine.
For reference the XPath is formed as follows
concat('/ns3:Result/ns3:t/ns3:c/ns3:e[',bpws:getVariableData('loop'),']')
But the error occurs at compile time not run time so I suspect the way the xpath is formed would not affect the compile
I'm suspecting the problem has something to do with the fact that I'm using the function without the optional "pat name" the variable "VariableDBResult" is defined by a schema not a WSDL message type. I have compiled the Array sample 112 which used a part name and it works but in my case without the part name it fails.
I attempted to cast the expression to a string and use a string variable, all to no avail.
Any help or suggestions will be greatly appreciated.
Regards
GraemeHas anybody got around this issue...I searched the forums but allI could get it unresolved threads pointing to this problem
getVariableData is not a literal expression
Re: getVariableData is not a literal expression

I want to mention that its a compile time issue and I am using Jdev 10.1.3.4 -
Remove element from multi-surface
Hi there,
I am trying to fix some invalid multi-surface geometries that are derived from a 3D source, many of which have ORA-54514: overlapping areas in multipolygon. I can find out which subset geometry (aka the element in this context) is causing the problem with the VALIDATE_GEOMETRY_WITH_CONTEXT function, and even extract just that element (SDO_UTIL.EXTRACT3D), but how do I remove that element from the geometry (and hopefully fix the problem)? Is there any way to view the position of the element within the geometry in the same manner that the Extract3D function requires (i.e. 0,0,1,1,0,0,7), I can return this for the problem element but not for any of the other subset geometries. Unfortunately I'm using FME to load the geometries and the topology validation here is not as robust as Oracle, which means I need to fix the geometries once they are loaded, but there doesn't seem to be any tools to do this?
Regards
DanHi Dan,
instead of removing the offending element, how about extracting all the correct ones? Should give the same net effect, I think.
Re FME: I find I can usually validate geometry enough that it will at least pass Oracle's Validate, but that's usually only 2D or 2D with a Z-ordinate (2.5D, as some folks call it).

Problem when removing elements from table after apply sort
Hi,
I have big problem with <af:table> and sorting.
When I removed objects from a table without sorting, there is no problem but when I removed
items from the table after sorting, the remain items are not correct.
For example, i have in my table these items :
Item AA
Item CC
Item ZZ
Item BB
Item AA
Item BB
Item CC
Item ZZ
I sort the table and i select the following Items : Item BB a Item CC
The remains item is only Item AA, Item ZZ disappear.
If i resort the table, the missing Item zz appear again in the table.
Here is my jspx :
<af:table var="row" rowBandingInterval="1" width="1050" rows="5"
rowSelection="multiple"
value="#{pageFlowScope.editNotificationBackingBean.ingredients}"
binding="#{pageFlowScope.editNotificationBackingBean.ingredientsTable}"
autoHeightRows="10" id="t2">
<af:clientListener method="goEditRow" type="dblClick"/>
<af:serverListener type="doubleClickOnRow" method="#{pageFlowScope.editNotificationBackingBean.handleRequestIngredientsSelectBtn_action}"/>
<af:column headerText="#{bundle.col_fr_name}" width="240"
sortable="true" sortProperty="name.FR_Description" id="c1">
<af:outputText value="#{row.name.texts['fr'].value}" id="ot1"/>
</af:column>
In my backing bean i call this method to remove selected elements :
public void unselectBtn_action(ActionEvent actionEvent) {
RowKeySet rowKeySet = selectIngredientsTable.getSelectedRowKeys();
int i = 0;
Iterator it = rowKeySet.iterator();
while (it.hasNext()) {
Integer index = (Integer)it.next() - i;
selectIngredientsTable.setRowKey(index);
CompositionIngredient compositionIngredient =
(CompositionIngredient)selectIngredientsTable.getRowData();
notification.getProductDetail().getCompositionIngredients().remove(compositionIngredient);
i++;
selectIngredientsTable.getSelectedRowKeys().clear();
AdfFacesContext.getCurrentInstance().addPartialTarget(selectIngredientsTable);
Thanks in advance.I have made a mistake, i don't paste the right <af:table> from my jspx.
Here is the correct one :
<af:table var="row" rowBandingInterval="1" width="1050"
rowSelection="multiple" id="tableSelectedIngredients"
value="#{pageFlowScope.editNotificationBackingBean.notification.productDetail.compositionIngredients}"
binding="#{pageFlowScope.editNotificationBackingBean.selectIngredientsTable}"
partialTriggers="::tab_ingredients_list_expressed_per">
<af:column sortable="true" headerText="#{bundle.col_name}" id="c5" width="180"
sortProperty="ingredient.name.FR_Description">
<af:outputText value="#{row.ingredient.name.texts['fr'].value}"
id="ot18"/>
</af:column>

The new LabVIEW 6i has a "Delete from Array" VI that will do this more

Hi
I would like to know how to remove repeitions from a 1D array. For example, AAANNNNDDDDKLL to ANDKL.
Also, what if the array is not sorted?
ArjunI have used this one in the past. But if anybody has a more memory effecient way to do it I would be happy to hear it.

Hi,
Can i remove a single item in my array or remove all elements???
Tnx all
Beck74This is a quick way to remove an element. It avoids looping which avoids an ArrayIndexOutOfBounds check with every iteration. Also, arraycopy is native which means that it is very efficient and suitable for large arrays.
public class arraytest
public static int[] remove(int _i, int[] _a)
int[] b = new int[_a.length-1];
System.arraycopy( _a, 0, b, 0, _i );
System.arraycopy( _a, _i+1, b, _i, b.length-_i );
return b;
public static void main(String[] args)
int[] a = {1, 2, 3, 4, 5};
// remove element 3
int[] b = remove(3, a);
for( int i=0; i<b.length; i++ ) {
System.out.println( b[i] );

Deleting elements from Arrays.
Hello,
I have to be able in this latest exercise to delete an element from an Array. I was wondering if you could give me code examples on how to do this. I am pretty sure that you have to read through the array and return "null" when you hit the element that you want to delete in the array.
Thank you.Look through the forum. There are at least two other threads open with people asking the same question.
