How can I create a variable size array?

How can I create a variable size array?

ok then how can i create a new vector object?If you don't know that, you need to go back to your text book and study some more. Or read the tutorial on the basics of Java: http://java.sun.com/docs/books/tutorial/java/index.html
After reading that you can move on to: http://java.sun.com/docs/books/tutorial/collections/index.html
Anyway, the answer to your question is, of course:
Vector v = new Vector();(But you should probably use ArrayList instead of Vector.)

  • How can i create "bind variable"

    How can i create "bind variable" in my DB to support any procedure in my DB.

  • How can I make a variable-size list  ?

    Hi guys,
    I'm trying to make a flexible list using <mx:List> component, I mean when I add an item or if the item size is changed (ex: collapse/expand) the list size must change.
    Is there an easy way to do that ? If you have any idea, please don't hesitate to post it here. Thanks in advance.
    Ygor

    It sounds like you're doing 2 distinct things; 1) adding new items to the dataProvider, 2) The item renderer is expanding or collapsing.
    If that is the case: 1) when you add an item to the dataProvider, increase the size of the list, 2) when the item renderer is expanding or collapsing, access the list through the "owner" property of the item renderer to change the size of the list.

  • How can I create a array with all files from a directory

    How can I create a array of files or varchar with all files from a directory?

    I thought the example could be improved upon. I've posted a solution on my blog that doesn't require writing the directory list to a table. It simply returns it as a nested table of files as a SQL datatype. You can find it here:

  • How can i reuse same variables that i create using c:set var="index" /

    hi all,
    please some one helpme!!!!!!
    how can i reuse same variable that i create using
    <c:set var="index" value="${0}"/>
    cause later in the program i use index to do some condition and based on that i increment ...
    so for example if i say...
    <c:if test="${index==0}">
    <c:set var="index" value="${index+1}"/>
    </c:if>
    will it be like
    if(index==0)
    index++;
    can i do like i did be4. if not what do i need to do to reuse. cause i use the variable atleast 5 time and its keep changing on diff condition level.

    Have you tried it?
    It should work, provided you are on the same page.
    The c:set tag creates the variable in pageScope by default.
    If you forward to another JSP you need to set the scope to be "request" so that it is still available.

  • When I import my Sony video, which is in m2ts format, the file size is a few times larger.  This affects the volume of clips for creating the blu-ray or DVD discs.  How can I squeeze the file size without sacrificing the quality of output?

    When I import my Sony video, which is in m2ts format, the file size is a few times larger.  This affects the volume of clips for creating the blu-ray or DVD discs.  How can I squeeze the file size without sacrificing the quality of output?  Is there any other ways of achieving this?

    Thanks.  I do not have the experience on burning discs from iMovie for the movie after editing (ie for video discs players).  It seems that i cannot find the relevant command in the tool bar for this purpsoe.  Would you please show me the way?
    The command is gone because iDVD has been discontinued by Apple. After Apple discontinued iDVD they removed the iDVD burning link from iMovie. I still use iDVD sometimes, only because I have an old copy.

Again, what is the best rate?  Furthermore, which format is more suitable or the best: H264 or mpeg 2/4?
    I don't know what RF means. When I have used HandBrake, I've used presets that apply to what I want to do, so I don't know the meaning of each individual setting. However, it appears that many of them are listed in the HandBrake User's Guide that is linked from the Help menu in the program:

    Photoshop is not amateur-level software, and although it can edit a video, it cannot burn a DVD. Unfortunately, because I still use iMovie, I haven't tried anything else. You might want to read the reviews of various DVD-burning applications in the Mac App Store.

  • How can I view my photos in "Events" like in iPhoto? How can I create events?  I have 55,000 photos and 1700 events so the only way I can possibly manage my photos is using events that are one slide in size.

    I have 55,000 images organized into about 1700 events. The only reasonable way to view my library is using events in iPhoto where each event has one image That still leaves 1700 images to sort through but that is a lot easier than 55,000 images.  In the side bar is a folder with "iPhoto Events" but those views still show all of the slides.  How can I create events and view my photos as events as in iPhoto?  Events are critical for large libraries and has been my primary way to sort images.
    Thanks!

    I had a problem a couple of months ago when iPhotos suddenly rearranged the order of my Events (Why won't iPhoto let me arrange my photos?) .  I was told "Use albums not events - events are not a good way to organize - albums and folder are designed for organisation and are very flexible".
    Haha!  I should have paid attention and read between the lines!  My iPhotos were highly organised groupings - not according to date but the way I wanted them - and it was so easy to do!  I see now that if I had them all in albums, as per the Apple Apologist suggestion, I wouldn't have this unholy mess I have been left with just to make iPhone & iCloud users happy.  I am now going through Photos and making Albums (of what used to be in my Events)  ... maybe I'll get this finished before they do another non user friendly update!

    Hi all,
    How can I use environment variables in a controller?
    I want to pass a fully qualified directory and file name to FileInputStream and would like to do it by resolving an env variable, such as $APPLTMP.
    Is there a method somewhere that would resolve this??

    The following is the code.
    My EBS server is installed with 2 nodes(one for current,and other is for application and DB).I want to copy the current server's file to the application server's $APPLTMP directory. But the result of "mCtx.getEnvStore().getEnv("APPLTMP")" is current server's $APPLTMP directory.
    Can anyone help me on this?

    However within OAF on the application it doesn't.
    what doesnt work, do you get errors or nothing ?XX_TOP is defined in adovars.env only. Anywhere else this has to go?

  • How can I create a high res image gallery, need to have print res photos for a pressroom section.

    How can I create a high res image gallery, need to have print res photos for a pressroom section.

    If you want Muse to "pass through" your images and not adjust, compress, crop etc - you need to place your images in the lightbox EXACTLY at the right size, pre-cropped and prepped in Photoshop.
    So if your light box is 800x600 the image you're dropping into that must be 800x600 exactly with no effects, rotation etc added to the lightbox frame. This stop Muse fiddling with your images, if they are perfect when inserted and you're not asking Muse to crop, expand, add effects etc. If it's perfect when inserted, Muse SHOULD also leave the resolution alone too, but I have not tried that one, but in theory, it should work.

  • How can I create a Text-Input Field in BexAnalyzer for a Planning Function

    Hello,
    i want to create a pre calculation(contribution accounting) for Materials in BI-Integrated Planning. These Materials aren't in the master data. So I create a new Info Object for pre calculated materials with only a material-number as key and a text-description.
    Now I want to write a Exit-Function, which creates new materials in these Info Object. The user should start this function in a planning application in BexAnalyzer. There the user should have the possibility to enter a text-description for the new material. How can I create such a Text-Field in BexAnalyzer and how can I read this text filed in a planning function (exit).
    Thanks in advance

    Hi Jürgen,
    you can create a parameter for this in the exit function and a variable for the parameter. In BEx Analyzer then create a button for the planning function; in the button parameterization use VAR_NAME = , i.e. use an Excel formula here to get the value from an Excel input field.
    The command range should be some 'hidden area' in your Excel sheet.
    But may be you don't need this. Use a characteristic without master data. Then ensure that that the query uses the option 'key' as display. In new lines you can then enter the key, the system creates a SID on the fly (but the text table will not be updated). In this scenario you may take text also from the key. May be you can update the text table (online or in batch) by simply using function modules from function group RSNDI_MD (not released by SAP).
    But observere that the system in BI Planning reads only the active version, i.e. if you change something on the fly the changes may not be visible.
    Regards,
    Gregor

  • How can I create a full-screen view of Keynote slide in Snow Leopard?

    How can I create a full-screen view of my Keynote slides in Snow Leopard?
    I'm going to be importing into ScreenFlow to create a video.
    Thank you!!

    Welcome to Apple Support Communities.
    Do you want static screen captures or motion video of slides as titles, bullet points, and the like are presented?
    Run the Keynote slide presentation in full-screen mode, then...
    Static full-screen captures - use Command+Shift+3.
    Static partial-screen captures - use Command+Shift+4 and use cursor to select the area of the screen to capture.
    If you want motion video as builds occur, why not use Keynote's built-in Share, Export function?
    (I'm on iLife '09.)
    Also understand that the default slide format for Keynote is 1024x768, not full-screen MacBook 1280x800 screen size, so you'll have wide black borders unless you change the default size or crop the finished screen captures.

  • How can I create a form for users wherein the text field will expand to accommodate additional text?

    How can I create a form for users wherein the text field will expand to accommodate additional text?

    You need to use LiveCycle (PC Only) to create a dynamic form like that.
    The best you can do with Acrobat to view all of the text in a field is to set the field to multiline, and set the size to "Auto" (If you don't set the size to 'Auto', you can enter as much text as you wish, but the user will need to use the scrollbar to view all of the text.)

  • How do I create a variable video delay of a live stream...

    I have a live video feed from my webcam in my Flash Application. I have a second video window next to it that I want to place a variable delayed video of the live stream. Therefore, I need to save the video stream in memory/disk and create this variable delay, say 5-60 seconds. As well as, continue to capture the live stream. The camera I am using suppots H.264 encoding.
    How do I create a variable length queue or buffer to hold the video stream coming into the flash application. Do I create a memory variable or write this to disk ? I have been looking over the ActionScript 3.0 documentation and I can not figure out how to code this either way ( as a memory variable or write to disk queue ).
    I want to be able to change the delay, view the delay stream in slow motion and scrub through the delayed stream.
    I would like to do this with out having to use Flash Media Server.
    Thanks,
    Bob

    I am sure it is practically impossible to accomplish that on the client side. Although theoretically it is conceivable to use NetStream.appendBytes() but it requires an extremely complex implementation.
    I suggest you look into FMS DVR capacities:
