Formatting Input and Output

Dear Forummembers
I am having some problem in formatting output in a Java code.Actually I have to worite some data into a text file about each product.
For each product there will be one line mentioning it's code, description and availaible quantity.As the code is of 6 digits I am having no problem in Aligning the code and description in each line.But as Description is not so, the availaible quantity can't be aligned columnwise.Can u pls help me.
I have one mor query too -
The program that I am writing has actually got Classes namely Product, Catalogue and Order.Product should be added to Catalogue and Order is used for accepting orders from Customers.Now I can't understand by one of the things as following -
"Much of the systems functionality requires you to manipulate a product object. Therefore, you need to be able to obtain a reference to the product that you wish to manipulate. It is advisable that you provide a method in the Catalogue class named getProduct, which accepts the product code and returns the reference to the relevant object. If the product code supplied to this method is not the code of a valid product (according to those that in the Catalogue), then you should return null"
I do understand what is mean by referece.But i am not clear about the functionality of the getProduct() method.After getting product code as the parameter, what should it return?
i would be grateful to you if you can kindly address this issue
Regards
RK

I don't really understand what you mean by the first part of your query, is this to align columns in the text file? Why are you using a text file to display the data instead of something with a more simple tabular layout?
As for the reference to the object, if the method must obtain the product from a list of products then presumably the method will be along the lines of:
public Product getById(String ID){
...//Loop through list of products until we find the ID
...//Return the Product with the specified ID (I'm presuming the ID is a variable in the Product class and not the ID in an array or list?)
}

  • (Input and) output formats from Photoshop Elements 6 for Mac

    I noticed that (until midnight PT, anyway) Amazon has Photoshop Elements for the Mac at a lower price than usual.  This brings up a question for me: What output formats can Photoshop Elements 6 produce?  In particular, can it produce PNG?  Also, can it accept PNG as input?

    I think that all the formats like .bmp, camera RAW, EPS,PICT, TIFF, Filmstripn, IFF, JPEG, Photoshop pdf, Photoshop RAW,PNG etc are supported for both input and output.

  • Simple input and output in a loop

    I'm trying to get some user input in a loop. This is a simplification.
    import java.util.Scanner;
    public class Main {
        public static void main(String[] args) {
            Scanner input = new Scanner(System.in);
            for (int i = 0; i < 3; i++) {
                System.out.println("Enter a string:");
                String myString = input.nextLine();
                System.out.println("output: " + myString);
    }In NetBeans, it usually runs fine for a few loops, but eventually (running the program 5 times or so) I get output like this:
    run:
    Enter a string:
    1
    output: 1
    Enter a string:
    output: 2
    Enter a string:
    2
    3
    output: 3
    BUILD SUCCESSFUL (total time: 9 seconds)It starts writing the prompt before the output and gets all jumbled. The problem is worse if I have more input and output statments in the loop. I thought it might just be a timing issue, but it doesn't matter how fast or slow I enter the information. After a few successive runs, the output always gets out of order. How can I keep in line?

    hi!
    why dont you try using printf it will give you a better formating capasities.
    it work like this.
    import java.util.Scanner;
    public class Main {
        public static void main(String[] args) {
            Scanner input = new Scanner(System.in);
            for (int i = 0; i < 3; i++) {
                System.out.println("Enter a string:");
                String myString = input.nextLine();
                System.out.printf("output: %s  \n" ,  myString );  // the %s is the place the string will apear
                                                                                       //and the \n is a escape caracter that creates a new line.
    }if you need more help with printf read this:

    data types used in a sub VI - selecting the correct input and output types?
    I can never work out how to choose an input or output format for Subvi's.

    GerdW,
    I realise now I have taken us in the wrong direction. apologies for that.
    History, this is not my code and I do not own the process and NOT my preferred method of using it. I was looking for a simple way to make subtle changes.
    What we do - We use these programs to collect data from typically 6 pressures and 6 temperature probes and capture RS232 / USB VISA strings from sensors.
    So every few weeks / months or up to a year we rearrange each sensor location to suit the new process. I did not write the code. I cannot change the procedure too much without resistance.
    So headers in the CSV file have the DaqMX string passed through the code. Great.
    Other data to the CSV file comes from calculations or extracted from the VISA string. Hence why we have headers with "Untitled 1 ()". These values also go to a History Chart.
    So I was looking for a simple way to read the the local variable label as it is always linked to the front page indicator. People can cope with editing the indicator label, save the VI and hit run.
    TL;DR - GerdW is now a psychologist.

  • Sound input and output gone

    After i updated to 10.5.4, my sound input and output disappeared. I've tried to update my quicktime once and i've also reinstalled the 10.5.4 update without any luck. I have a Leopard dvd, but i'm not sure whether i'm able to only install the sound drivers once again? Any other suggenstions?
    thanks in advance

    Thanks.
    I did reinstall the combo, if you mean this one; http://www.apple.com/support/downloads/macosx1054comboupdate.html. And it didn't help, there isn't anything in input or output in the sound preferences panel.
    Isn't it possible to perform an install of the sound drivers without having to do a total format? I've looked through my leopard disk content and checked all the optional installs and haven't been able to find them.. Can i download them seperately somewhere?

  • How can I use a different driver for audio input and output?

    I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
    What I am trying to do is:
    1) Record into Logic Express using my Tascam US-122.
    2) Have playback come out of my computer sound system, not the Tascam.
    If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
    So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!
    -allen

    Yes it should do what you want.
    Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
    Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

  • SSIS: How to use one Variable as Input and Output Parameter in an Execute SQL Task

    Hello,
    i need your help,I'm working on this issue since yesterday and have no idea how to deal with it.
    As I already said in the tilte i want to start a stored procedure via a Execute SQL Task which has around 15 prameters. 10 of these should be used as input AND output value.
    As an example:
    i have three  Variable:
    var1    int        2
    var2    int     100
    var3    int     200
    the stroed procedure:
       sp_test
          @var1 int
          @var2 int output
          @var3 int output
       AS
       BEGIN
            SET @var2 = @var2 * @var1
            SET @var3 = @var3 + @var1
       END
    So in the Execute SQL Task i call the Stored Procedure as follwos:
        Exec sp_test  @var1 = ?, @var2 = ? output, @var3 = ? output
    (I use an OLE DB Connection)
    The parameter mapping is as follows:
    User::Var1        input                   numeric              0                 -1
    User::Var2        input/output         numeric              1                 -1
    User::Var3        input/output         numeric              2                 -1
    Now my problem. If i set  Var2 and Var3 as Input parameter the values are still the same after running the package. If i set them to a output value the are both Null because the procedure doesnt get any values.
    I already tried to list them a second time - like
        User::Var2        input                  numeric              1                 -1
        User::Var2        output                 numeric              1                 -1
    or i use a new variable
        User::Var2                  input                  numeric              1                 -1
        User::Var2Return        output                 numeric              1                 -1
    but i alwas get the error
    "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
    Has anybody an idea how I can solve this problem?
    Thanks a lot.
    Kind Regards,
    Alice

    Hi Alain,
    thx for your answer.
    I have around 15 procedures called one after the other to calculated and modify my values. Each procedure is responsible for an other but overlapping set of variables. So i thought it would be a good idea to call them one after the other with the needed variables via a execute sql task.
    So if i use a result set, how i get my stored procedure to return 10 values? I would have to use a Function instead of a procedure, wouldn't i?
    As if i have 15 procedures this would be a lot of work.
    But thanks a lot for the idea. I think an other idea would be to create one function which calls all stored procedures and returns all the calculated values as a result set, wouldn't it?.
    Kind Regards.

  • How can I make Apple Earphones be the Input and Output for Audio

    I have some older headphones and they aren't compatible with a Mid 2010 (Intel Core i3) 21.5 Inch iMac
    Is there some way to make Apple Earphones be the Input and Output for Audio in the iMac
    This is a problem for me personally as when I am talking to someone on Skype the iMac picks up the In-built Microphone audio, and yes the headphones I'm using do work straight from the iMac as audio output
    Any help is appreciated

    you can connect the headset to something like this

  • How do I create an xControl with multiple inputs and outputs?

    Hello,
    i am trying to write a new Xcontrol Element. In the data model I can create data types using the cluster to create compound types, eg an int and an int array. But how do I create an xcontrol which has multiple data inputs and outputs?
    Kind Regards

    Limping_Twerp wrote:
    Alright: I see: An xcontrol is either an input OR an output. How do I achieve an output? Secondly: So you are saying the only Elements that can have multiple inputs and outputs are VIs?
    Can you take a few steps back and explain what you are actually trying to do. SubVIs and Xcontrols have nothing in common and it is not clear why you even try to compare them side by side (e.g. in terms of the number of connectors).
    Your questions about input or output tell us that you seems to have some misconceptions about xcontrols. Xcontrols are like regular controls, except they have some built-in intelligence that you can program. Most front panel object can be either controls or indicators and the same is true for Xcontrol. You create an Xcontrol, and after placing it on the front panel you can decide if it should be a control (where the code reads the value) or an indicator (were the code writes values to it). When you define the xcontrol facade, you also need to program how the visuals change if it is changed from control to indicator or vice versa.
    As a first step, you should opend the example finder and look at some xcontrol examples.
    Again, what are you actually trying to do?

  • FINALLY INPUTTING and OUTPUTTING Annotations!

    Ok, before everyone thinks that this is a very bad solution, I have to tell that I`m no programmer and my knowledge of PostgreSQL, Ruby or any other language is very poor.
    With useful help from Jamie Hodge, fbm and Nicholas Stokes (mainly)
    I could manage to write a command for inputting and outputting from Final Cut Server Annotations.
    So lets go to the fun part:
    INPUTTING:
    1- Create a Response called "Annotations IN" (or whatever you want):
    a - Reponse Action: "Run an external script or command"
    b - Run Script > *Commnad Path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
    Command Parameters: psql px pxdb -c "COPY pxtcmdvalue FROM '/FCSRV/annotation-in.txt' USING DELIMITERS '|';"
    2 - Create a poll Watcher with name: "Watch for Annotations IN"
    a - Enable: true
    b - Monitor Address: Chooses a Device (create a new one or use a tmp one) and path to where you`ll going to put a txt file with the annotations.
    c - Response List: Choose the Response you created "Annotations IN" in my case.
    d - Event Type Filter: Created, Modified
    e - Poll Watcher > Listing Frequency: 2 (or any number of seconds you feel like it).
    Listing multiple: 2
    Wildcard include Filter: *.txt (or any custom extensions you want)
    3 - Create a txt file and use this as a template:
    {ASSET_ENTITYID}|1527|{TCIN}/(30000,1001)|{TCOUT}/(30000,1001)|{Annotation}|{USE RID}|{DATE}
    Where:
    {ASSET_ENTITYID} = Is the entityid of your asset. You can find what number it is by issuing:
    /Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxentity.address LIKE '/asset/%';"
    This will output ALL your assets, so if you know the name or want to parse the name you can use:
    /Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxmdvalue.value='ASSETNAME' AND pxentity.address LIKE '/asset/%';"
    Where in ASSETNAME you`ll have to put your Asset Name without extension.
    {TCIN} and {TCOUT} is, of course, the TC`s points. In the form of: HH:MM:SS;FF
    {Annotation} is the commentary.
    {USERID} (in my case was 1)
    {DATE}: This one is tricky. My example is 2009-03-15 19:31:15.839795-03
    So is in the form YYYY-MM-DD HH:MM:SS.????? I really don`t know the rest. Could be milliseconds?
    Of course one can write a script to translate everything from a txt file like:
    ASSETNAME | TCIN | TCOUT | ANNOTATIONS | USER
    But as I`ve said I`m no programmer
    Ok.. now the time for the OUTPUT:
    The command-line is:
    /Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value='ASSETNAME';"
    Where ASSETNAME is the Asset name without the extension.
    Or issuing the following to OUTPUT ANNOTATIONS from ALL assets:
    /Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "select * from pxtcmdvalue;"
    Adding "> /PATHTO_WHERE_IN_WANT/ANNOTATIONSOUTPUT.TXT" at the end will put all output into a txt file.
    It`s possible (in theory) to:
    1- Create a boolean md field in FCSRV called "EXPORT Annotations" (don`t choose lookup)
    2- add or create a md group called "Export Annotations" and add the above md field to it (don`t choose lookup)
    3- Add "Export Annotations" md field to Asset Filter md group
    4- Make a Response for Running external command. Command path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
    Command Parameters: psql px pxdb -c 'SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value=[FileName];' > ~/Desktop/ann-out.txt
    (I`m having problem with this, it doesn`t work).
    5- Make a Subscription that if Export Annotations modified = true, trigger if changed and trigger the Response above.
    6- Add exporting annotations md group to Media md set.
    In theory it`s possible to modify the FinalCutServerIntegrationSample get and input annotations instead of adding another "comment" field to md group list.
    Few!
    Ok so please help beautify this out!
    This will be very useful for a lot of people.... We know that it`s only a matter of time to FCSVR have this function built-in... but this "time" could be years.
    So let`s start ourselves!
    Thank you very much!!
    Regards!

  • How to temporally match/save Input and Output Channels's data?

    Hello, I have a voltage-input, voltage-output SISO system, and need to indentify its dynamic response (or transfer function) as a reference to a PID control. Without using the system identification toolbox, my goal is to generate/provide a sine sweep input (ranging 1Hz-5kHz for 10sec) to the system and to save the corresponding output response signal as well as the sweep input signal simultaneously.
    I got a sample program online and am trying to modify it as attached, but I really need your advices/comments concerning several problems I am facing with:
    1) With the below setting, the number of the acquired Input channel samples obtained is 5461, which is smaller than expected (i.e., 10000). What would I be missing in setting parameters?
    - H/W: NI-USB-6341 DAQ
    - AO: continuous samples with the waveform timing (1k sampling, 10000 samples => 10 sec, slower sampling just for testing purpose)
    - AI: continuous samples, samples to read: 30k, rate: 1k
    2) I am using flat sequence structure as a way to making the start point of saving AI and AO data same, but wonders if this is a right method or if there is other better approaches. (I had an idea of using an internal clock with "1-sample mode" for sync, but this may not work at the high speed sine sweep like 5kHz, right?)
    3) I just want to provide the sine sweep just once to the system and do not require the "reset" functionality implemented in the original sample program. I failed to remove this "reset" part as I did not fully understand the sample code. If I run the attahed, the generated AO signal is periodically provided to the system. Please give me any advice to modify the program as I want.
    Thanks for your help and valualble time.

    Hi J. Kim,
    To begin, you say you want to synchronize your analog input and output so that they start at the exact same time, yes? To achieve tight synchronization, you need to use DAQmx VIs instead of the DAQ Assistant. There's a good overview of DAQmx VIs  here. There's also a document that deals specifically with synchronization in DAQmx here. Additionally, if you go to Help>>Find Examples in the LabVIEW example finder, you can see many other examples of acquiring data using DAQmx.
    As for your configuration, you have your analog input DAQ assistant wired far before your analog output DAQ assistant in your sequence strucutre, so the dataflow of the program will cause the analog input DAQ Assistant to execute before the output. They cannot be in different sequences if they are executing simoultaneously, and I would not use flat sequences here except to start the two tasks in DAQmx. Where did you find this example?
