    etc...
    how can i read the contents of this textfile and put the data into an ArrayList called ArrayList<Customer> customerList.
    i knew that i need two classes, one for CustomerDetails and one for ReadFile.
    i have already done the customer class as:
    import java.util.Date;
    public class Customer
        String Name;
        int CustomerNo;
        String Postcode;
        String teleNo;
        Date lastModified;
        public Customer(String Name, int CustomerNo, String Postcode, String teleNo, Date lastModified)
         assign(Name, CustomerNo, Postcode, teleNo, lastModified);
        public void assign(String Name, int CustomerNo, String Postcode, String teleNo, Date lastModified)
         this.Name=Name;
         this.CustomerNo=CustomerNo;
         this.Postcode=Postcode;
         this.teleNo=teleNo;
         this.lastModified=lastModified;
        public String toString()
         String allDetails = "Name: "+Name+
             ", Customer No: "+CustomerNo+
             ", Postcode:"+Postcode+
             ", Telephone No: "+teleNo+
             ", Last Modified Date: "+lastModified;
         return allDetails;
    }i just wondering how can i code the ReadFile class?
    can anyone help me please. thank you in advance.

    thank you for your suggestion, but i have already started to code the readCustomer class using the Scanner.
    the code i got so far is:
    import java.util.Scanner;
    import java.io.*;
    public class readCustomer
        public static void main(String[] args)
         readCustomer("Customers.txt");
        public static void readCustomer(String filename)
         try {
             Scanner scanner = new Scanner(new File(filename));
             scanner.useDelimiter(System.getProperty("line.separator"));
             while (scanner.hasNext()) {
              processLine(scanner.next());
             scanner.close();
         } catch (FileNotFoundException e) {
             e.printStackTrace();
        public static void processLine(String line)
         Scanner scanner2 = new Scanner(line);
         scanner2.useDelimiter("\\s*:\\s*");
         String description = scanner2.next();
    *// here is where i am struggling. i don't know how to get the information after the : sign*   
    }i am currently struggling with the processLine method?
    also, i am not sure how to group a set of information and put them into the arraylist.
    Any hint, please. Thank you.

    >
    Why are you wasting your time coding from scratch using the PL/SQL Web Toolkit instead of the APEX framework?
    From Re: how to write a file using mod pl/sql it appears that you are not using APEX, so a number of the approaches APEX offers are not relevant. You appear to be looking for a file download solution using the <tt>wpg_docload.download_file</tt> method, such as:
    create or replace procedure download_file (
        p_filename  in     varchar2
      , p_mimetype  in     varchar2
      , p_content   in out nocopy blob)
    is
    begin
      -- Set up HTTP header.
      -- Use "application/octet" as default MIME type.
      owa_util.mime_header(nvl(p_mimetype, 'application/octet'), false);
      -- Set the size so the browser knows how much to download.
      htp.p('Content-length: ' || dbms_lob.getlength(p_content));
      -- Filename will be used as default by the browser in "Save as..."
      htp.p('Content-Disposition: attachment; filename="' || p_filename || '"');
      -- Close header.
      owa_util.http_header_close();
      -- Stream the file content to the browser.
      wpg_docload.download_file(p_content);

  • How to write text file in Shockwave?

    Does anybody know how to write text file in Shockwave to
    user's disk?
    Thanks in advance.

    Those Xtras can wreak to much havoc when used with the wrong
    intent.
    What you can do is write with setpref and store a list of
    saves and the
    saves itself seperatly. Then you'd have to build your own
    save/open
    dialog to let the user:
    * pick a previously saved file to load or overwrite
    * have the user type the name of a new file to save.
    Only thing that remains is that the user cannot decide where
    the files
    are saved.

    Sorry about the long lines.
    As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
    When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
    Does anybody have an idea to solve this?
    Thanks a lot!!

    you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
    your code is doing too much..and hard to follows..
    1. get the selected files
    for each selected file
    process the file and return the result
    write out the result.
    /** close the precious resource */
    public void closeResource(Reader in){
        if (in != null){
            try{ in.close(); }
            catch (Exception e){}
    /** get the total number of line in a file */
    public int getLineCount(File file) throws IOException{
        BufferedReader in = null;
        int lineCount = 0;
        try{
            in = new BufferedReader(new FileReader(file));
            while ((in.readLine() != null)
                lineCount++;
            return lineCount;
        finally{ closeResource (in);  }
    /** read the file */
    public void processFile(File inFile, File outFile) throws IOException{

            String line = null;
            while ((in.readLine() != null){
                .. do something with the line
                result.append(....);
            writeToFile(outFile, result.toString());
        finally{ closeResource (in);  }
    public void writeToFile(File outFile, String result) throws IOException{
        PrintWriter out = null;
        try{
            out = new PrintWriter(new FileWriter(outFile, true));  // true for appending to the end of the file
            out.println(result);
        finally{  if (out != null){ try{ out.close(); } catch (Exception e){} }  }

    I have a Dell Inspiron E1505, and I use Kaspersky Internet Security. The past week, I've had problems opening Firefox - it has been slow. Today, it just won't open at all. At first I thought it was my Internet connection, so I called my provider, Comcast Cable. But I was also able to open Internet Explorer. I was told that I may have to remove Firefox, and redownload it, but it would erase all my bookmarks. How can I access Firefox and save my bookmarks?

    Try starting Firefox in Safe Mode (Firefox Safe Mode, not Windows Safe Mode).
    First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
    Next, check out this article:
    [http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Be careful not to "reset" anything permanently if you didn't back up.
    To export bookmarks to an HTML file that IE and other browsers can read, see [https://support.mozilla.com/en-US/kb/Exporting%20bookmarks%20to%20an%20HTML%20file Exporting bookmarks to an HTML file | How to | Firefox Help].
    Any luck?

    Bonjour VAGRAI
    1) To write math expressions in a text :
         — Microsoft Office 2011 etc. for Mac use its included Equation Editor.
         — OpenOffice.org (OOo) and NeoOffice : download free Dmath 3.3.
         — iWork (Pages, Numbers, Keynote), download free MathType 6.7, fully functional for 30 days, then becomes « Lite » for life as good as the Microsoft equation editor ; it’s better than using Grapher’s equation editor (Applications > Utilities) because MathType can be called from Pages and allows editing equations by clicking the math expressions your text (details on MathType website) .
         — Graph.app 2.3 in Mountain Lion is built to draw curves and surfaces from equations, so it uses an equation editor less powerful than mathType, but it’s easier typing expressions. You may get 2D 3D geometrical drawings from clever equations. Suggest a glance at   http://y.barois.free.fr/grapher/  to know all about Grapher (83 pages Instructions for Use - Grapher) and some examples
      2) Geometrical schema :
         — GeoGebra is very popular and used by math teachers.
         — Google SketchUp 8 was not built for mathematics but for architecture, but it’s very easy using it to draw 2D 3D surfaces and solid figures.
         — ShapeOnYou.app allows simples geometrical figures  http://pierre.chachatelier.fr/programmation/shapeonyou_en.php
    3) Some useful websites for screen shots of geometrical schema :
         http://www.mathcurve.com/
         http://perso.orange.fr/roger.assouly/
    Drawings files PDF, TIFF, JPG … can be inserted in an iWork window (Pages).
    I hate LaTex : not necessary to write math books !  
    Au revoir VAGRAI,
    YB24
    Attachment : lines and curves were made with Google SketchUp 8, screen copied (Command-Shift-4), inserted on a Pages sheet to add letters figures rectangles title.
    SketchUp allows drawing precisely an arc of circle 325 mm radius 22,5° angle for instance.

    Ntenich,
    If your table has a Header and your Legend text is in the header, it will be picked up by the table.
