Remove blank element in array
need help how to remove empty elements in an array?
Hi jeyanthi,
if you want to delete somthing from a txt file, you have also first to read the data, remove the part you want and to write the new data into the file. So i think you can do it with the array version. For example something like this:

WebDynpro Java: how to remove blank element from Table and Dropdown.
Hi Folks
In a webdynpro application,
I created a table and witten the below code to populate the table
IPrivateDummyView.IFirst_TableElement First_Table_Element = null;
First_Table_Element = wdContext.nodeFirst_Table().createFirst_TableElement();
First_Table_Element.setF_Value("One");
wdContext.nodeFirst_Table().addElement(First_Table_Element);
First_Table_Element = wdContext.nodeFirst_Table().createFirst_TableElement();
First_Table_Element.setF_Value("2");
wdContext.nodeFirst_Table().addElement(First_Table_Element);
As per the code, i got 2 row in the table.
But , i have one Empty row on top of the table , how to get ride of this.
i find the same problem happening with dropdown too, where i used DDBI, i populated a the content as mention, but i initial 2 row as blank and then i have my own elements ,as per my code.>

Remove an element in Arrays Object
If I only can use object Arrays, how can I perform remove element action?
=> a={1,2,}What should the last element be? If it is an array of primitives, there is no "empty" value.
But why do you want to do this anyway? It sounds very much like you need to use an ArrayList. -
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?
thanksYou 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. -
How to remove blank data from a byte array
Hi All,
How to remove blank data from a byte array. Suppose I created a byte array as byte[] b = new byte[8192] and i read the data as inputstream.read(b). If the data that has been received is only 1000 bytes length, how to find out how much data has been read or how to delete that blank 7192 bytes of data?
Thanking you,
Regards,
Shankar.1) Always try to sidestep this by allocating only the necessary amount of space required...
2) If 1 is not possible, you will have to index byte for byte how much data was read into the array which
denotes reading byte for byte... not ideal as this is relatively slow...

How to removie a duplicate element of array
i have this code so far can someone please help
public static int [] remove(int[] a, int[] b){
for(int i = 0; i < a.length; i++) {
if(a[i] == b) {
int[] newInt = new int[a.length - 1];
return newInt; // We need something here
return a;First, please use [ code] and [ code] tags to denote code; it makes it much more readable.
Second, your arguments for the function don't make sense with relation to your subject. So, running on the asumption that I know what you mean through the subject, here goes:
You probably want the arguments to be:
(int[] a, int b)Whereby you want to remove the element that equals b . So, what you would want to do in such a situation is:
for(i = 0 to a.length) {
if(a[i] == b) {
//You have reached the element to throw away. Set a flag saying you have reached this point
// If the flag is set, add a[i+1] to the new array; otherwise add a[i] to the new array.
return a; -
Removing movie clips in arrays
Hi there
I have this code in my Flash file:
for(bubble in bubbleArray){
bubbleArray[bubble]._y -= 3;
if(bubbleArray[bubble]._y < 370){
bubbleArray[bubble].removeMovieClip();
I'm wondering, when I remove the movie clips should I also be popping them from the array?
I have an onEnterFrame function that attaches the movie clips and pushes them into the array, so I'm worried that if I don't pop them the array will continue to increase in size and slow down the movie. Is this the case, or will they be automatically removed from the array by the removeMovieClip() method above?Looks like I spoke too soon. I imagined that removing them from the array would be easy, but I'm struggling.
The movie clip that is removed from its parent clip and should be removed from the array will not always be the first element in the array, and I'll need to remove multiple clips at a time. I've put in a trace action to trace the length of my array, and after about ten seconds it contains about 2500 elements, most of which have already been removed using the removeMovieClip() method. I'm worried this will slow down the movie.
So to clarify: How can I remove these elements from my array when I remove them from the stage?
I tried to include something like:
while(bubbleArray[0] == undefined){
bubbleArray.shift();
but it caused Flash Player to freeze up. Also, if I trace bubbleArray[0] it is only "undefined" before something is pushed into the array. Once the clip has been removed from the stage, the trace just returns a blank line, not "undefined".
I'd appreciate any help.
Here is all my code:
stop();
splash.stop();
var i:Number;
var j:Number = 0;
var minBubbles:Number = 10;
var maxBubbles:Number = 20;
var bottomBubbleLimit:Number = 0;
var topBubbleLimit:Number = 1;
var bubbleNumber:Number;
var bubbleX:Number;
var bubbleY:Number;
var bubbleScale:Number;
var bubbleMinScale:Number = 30;
var bubbleMaxScale:Number = 100;
var fewerBubbles:Number;
var ring:String;
var ringArray:Array = [ringAnimation.ring1, ringAnimation.ring2];
var bubbleArray:Array = [];
ringAnimation.onEnterFrame = function(){
for(ring in ringArray){
if(ringArray[ring]._y > 370){
bubbleNumber = (minBubbles + (Math.random() * (maxBubbles - minBubbles)));
for(i = 0; i < bubbleNumber; i++){
bubbleX = ((ringArray[ring]._x - (ringArray[ring]._width / 2)) + (Math.random() * ringArray[ring]._width));
bubbleY = ((ringArray[ring]._y - (ringArray[ring]._height / 2)) + (Math.random() * ringArray[ring]._height));
bubbleScale = bubbleMinScale + (Math.random() * (bubbleMaxScale - bubbleMinScale));
ringAnimation.attachMovie("bubble", "bubble" + String(j), this.getNextHighestDepth(), {_x:bubbleX, _y:bubbleY, _xscale:bubbleScale, _yscale:bubbleScale});
bubbleArray.push(ringAnimation["bubble" + String(j)]);
j++;
for(bubble in bubbleArray){
bubbleArray[bubble]._y -= 3;
if(bubbleArray[bubble]._y < 370){
bubbleArray[bubble].removeMovieClip();
trace(bubbleArray.length);
if(ringAnimation._currentFrame == 6){
splash.gotoAndPlay(1);
}else if(ringAnimation._currentFrame == 12){
splash.gotoAndPlay(1);
fewerBubbles = setInterval(reduceBubbles, 600);
function reduceBubbles(){
if(minBubbles > bottomBubbleLimit){
minBubbles--;
if(maxBubbles > topBubbleLimit){
maxBubbles--;
if(minBubbles == bottomBubbleLimit && maxBubbles == topBubbleLimit){

Dear all,
How can i remove blank pages in combind pdf in one short, if you have any idea or suggestion for remove blank pages in Acrobat. We need without blank pages counting for final page count purpose.
We tried to remove blank pages option in acrobat 9.0, but it is not use single short. It is taken more time to taken for maual work.
If you have any scripting for this? or any option having in acrobat in single short? Please help me in this regard.
Thanks
kanaga kumar. kThis can be done with a script, but a script can only assume a page is
blank if it has not text in it. It can't know if there are images or other
graphic elements in a page. -
Removing specific element from a list
Hello, I'm very new to java, and to programming in general.
I'm trying to write a secret santa app for my family for christmas. Essentially the idea is that 7 names are put into a list, and each time a name is "pulled" (i.e. randomly assigned to a name /= itself) it will be removed from the list of available names to assign.
String[] nList = { name2, name3, name4, name5, name6, name7 }; // store names for random use
Random r = new Random();
name1assign = nList[r.nextInt(nList.length)];
String[] nList2 = { name1, name3, name4, name5, name6, name7 };
name2assign = nList2[r.nextInt(nList2.length)];
My goal for this is to take the string that is equal to name1assign, and remove an element with that string from nList2.
Can anyone give me some advice in this matter?
Thanks.Sometimes a null value is used to indicate an 'empty' array element, but it would be better to try collections instead.
You could use an ArrayList instead of an array. This has methods to remove items by index or value.
An ArrayList also works with Collections.shuffle, which allows you to simply iterate over the list and not deal with random or removing elements at all. -
Ho to remove duplicate element in the List ?
It seem to be very basic, but it not working, even I try different way.
This my List [10, 10, 11, 11, 12, 12, 13, 13, 14, 14],
now to remove duplicate elements to have at the end [10, 11, 12, 13, 14]
my code seem to be perfect but...
for(int i = 0; i < listA.size(); i++){
if(i%2 == 0){
System.out.println("ce i est un nombre pair "+i);
listA.remove(i);
System.out.println(listA);senore100 wrote:
The problem is that every single time an element is removed, the whole ArrayList is re-shuffled, with all the elements to the right moved to the left on spot. That's why.Yes, that's right. However if you had used an Iterator over the list, you could easily have removed every other element. It's only when you use an array index that you run into this (very common) problem. -
How to eliminate or remove zeros from 1D array
How to eliminate or remove zeros from 1D array. Let say I have 1D array having foolowing elements
"0 0 0 0 0 4 0 0 9 0 0 1 4 0 0 0 0 0 0 0 0 10 9 0 0"
So after removing or eliminating zeros it will become as follow
"4 9 1 4 10 9"
So can any body guide me how can I do that? See attached Image for details.
Thanks

Here are 2 example .vi's I made based on altenbach's removeZeroes.png in this discussion thread:
It seems pretty pointless to post those because no new useful information is given.
Currently, only the input is defined in the connector pane, making them useless as subVIs.
unlike my example using integers, an "=0", like any "equal" comparison, is potentially dangerous with DBLs.
Reshaping a 2D array to 1D before removing zeroes is pretty pointless because a 2D output cannot be recovered. A more interesting scenario would be to remove some columns or rows (e.g. that are all zeroes) from a 2D array.
You should also clean up the front panel, e.g. properly zero the upper left corner, make the controls/indicators nicely labeled, sized and arranged, and maybe even add scrollbars to the arrays.
Thank you for those comments.
Now the input and output are defined (in the updated attachments) for use as example subVI's. I also cleaned up a few visual details, but I leave the rest for others to cater to their specific uses if they don't want to use this as a subVI (or at least as-is), such as changing the icons or changing to integers instead of doubles.
I'm not sure about what you mean exactly with "=0" being "potentially dangerous with DBLs". I'm guessing you had a certain case scenario in mind. Although the subVI's seem to work fine within my larger program and situation, my situation may not generalize with regards to this point.
I reshaped from 2D to 1D, with a 1D output, because it could be helpful for things like when later processing just needs a 1D array. For example, in my situation I had to remove a huge spike of unnecessary "0"'s from a previous subVI that were affecting the output display of a certain histogram. So it turned out a 1D array output was helpful, and you never know what problems come up, so I included the 2nd example.
Hopefully if someone is looking for this, they can just use or play with an example subVI (granted that they know how to plug things in for their context). I was hoping to post a subVI people could put to direct use. -
Remove Blank Values from Slicer in Power View
Hi all,
I am trying to create a power view report from a power pivot data model. After creating the model when I try to use the slicer in power view I am seeing the Blank record. Then I checked that dimension in model where I don't have any blank value in there.
Also I checked in fact table where it has a relationship with that dimension and I don't see any blank value there as well.
I am currently blocked with this issue. Experts please jump in and give some ideas how to remove blank value from there.
ThanksAs MM-99 already stated correctly, the BLANK-member is created if there is one or more non-matching row in your fact-table that does not exist in the dimension-table
maybe you have some issues with upper and lower case?
or maybe there are some whitespace characters contained in the text?
to identify the issues you may want to create a calcuated column in your fact-table as =RELATED('DimTable'[MyKeyColumn])
then you can filter on that column and see if any blank values appear
hth,

Creative Zen 32GB - how do I remove blank FM presets???
How do I remove blank presets from the FM list? I have about 20 stations set up as presets but the other 2 blank ones are still there. Delete doesn't delete them. All delete does is to erase the station from a preset that has a station programmed into it. I want them GONE so that when I sequence through the station presets I don't have to go through the 2 blank ones to get to the next good one. If this is not possible, holy cow, what an oversight on the part of the programmers! Please tell me this can be done!
This is for a Creative Zen 32GB. Not a Zen V or a Zen XFi. Just a Zen. Just a plain Zen.
Thank you.Wow. That's very odd indeed. Seems pretty logical to be able to do that. There's no way I could program in 32 stations and I li've in a major radio market. There are not 32 stations I'd ever be interested in listening to around here and I don't even think there are that many even on the air. Again, since that's software related, please put that in a firmware update.

Data Merge - Not removing blank lines when more than one in a row
I am having the same problem as mentioned here: http://forums.adobe.com/message/2109531#2109531 That post is for some reason set as "answered" though the poster said the latest update did not resolve the issue. Has anyone found a solution to this issue?
Thanks much,I"d suggest you try running the merge WITHOUT removing blank lines, then use GREP to remove empty paragraphs. There's a pre-written saved query in the list.

Remove text field from Array via for loop
Hi,
i have a problem to remove text fields added via for loop.
That im doing is, via for loop im dynamically creating menu with 10 buttons.
Each button contain, dynamically created, background (shape) and text field.
And everything is fine.
