How to read non-java binary file?

Hello Team,
I have problem to read non-java binary file.
Let me explain.... I have one binary file created in vc++ having fix structure. Structure of file is like String,int,int,int.
Now I have to read this file in my java application. I am failed to identify length of String value of Structure in java.
Can any body help me to solve this problem?
Thanks in advance.

Thanks for guide me,
I have try using 0x00. And its working.
Now I have another problem:
in file.ext , I have written one record having structure string,int and int.
I have enter data as "HelloWorld", 100 and 111.
To read first record from file file.ext, following code I am using:
try
     FileInputStream fis = new FileInputStream("file.ext");
     DataInputStream in = new DataInputStream(fis);
     char ch;
     while((ch=(char)in.readByte()) != 0x00)
          System.out.print(ch+"");
System.out.println();
     System.out.println("Integer 1 --> " + in.readInt());
     System.out.println("Integer 2 --> " + in.readInt());
     in.close();
     fis.close();
catch(Exception ex)
     System.out.println(ex.toString());
And I am getting following output:
HelloWorld
Integer 1 --> 0
Integer 2 --> 0
File file.ext is created in vc++
I am not getting integer data. Plz guide me for this problem.
Thanks in advance

  • How to read/write a binary file from/to a table with BLOB column

    I have create a table with a column of data type BLOB.
    I can read/write an IMAGE file from/to the column of the table using:
    READ_IMAGE_FILE
    WRITE_IMAGE_FILE
    How can I do the same for other binary files, e.g. aaaa.zip?

    There is a package procedure dbms_lob.readblobfromfile to read BLOB's from file.
    http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#sthref3583
    To write a BLOB to file you can use a Java procedure (pre Oracle 9i R2) or utl_file.put_raw (there is no dbms_lob.writelobtofile).

  • How to read a text/html file in java regardless of its encoding?

    Hi All,
    How to read a text/html file in java regardless of its encoding?
    1. Is there any way to identify that a file (read using FileInputStream/or any other means with java.io package) has been saved with which type of encoding i.e. whether the file is using ANSI encoding or Unicode encoding or other?
    2. Is there any standard way to read an encoded file (i.e. files having UTF-16 format for Asian locales character support) and un-encoded file (i.e. files having ordinary ANSI format) correctly without knowing the user input?
    The problem is that while creating an instance of 'InputStreamReader' (ISR) we can pass the encoding type used (otherwise it takes the system's default encoding type), and the ISR expects the file to be in the same encoding format otherwise it reads it as some junk. But we don't know which file the user is going to pass whether it is Unicode (for Asian locales file should be in Unicode) with or ANSI coded (for non-Asian / English locales user generally uses ANSI encoding).
    Regards,
    Sam

    1. There is no reliable way of guessing the encoding of a file without that information. Thats why XML for example has very strict rules wrt. it's encoding (short form: use UTF-8 or UTF-16, if you use anything else, you'll have to specify it)
    2. you might be able to make an educated guess if the possible range of encodings is limited, but it will probably never be 100% certain
    3. The HTML file might have a header entry "<meta http-equiv..." that tells you about it's encoding. You could try to read the start of the file and see if you find that, then if you found it re-read the entire file.
    regards

    Instead of cross-posting unformatted code you could have taken a look at the API, because there you might have come across a method named getLinks...Even though it's not documented, I really suspect that it will return the Hyperlinks on a given page.

  • How to read appended objects from file with ObjectInputStream?

    Hi to everyone. I'm new to Java so my question may look really stupid to most of you but I couldn't fined a solution by myself... I wanted to make an application, something like address book that is storing information about different people. So I decided to make a class that will hold the information for each person (for example: nickname, name, e-mail, web address and so on), then using the ObjectOutputStream the information will be save to a file. If I want to add a new record for a new person I'll simply append it to the already existing file. So far so good but soon I discovered that I can not read the appended objects using ObjectInputStream.
    What I mean is that if I create new file and then in one session save several objects to it using ObjectOutputStream they all will be read with no problem by ObjectInputStream. But after that if in a new session I append new objects they won't be read. The ObjectInputStream will read the objects from the first session after that IOException will be generated and the reading will stop just before the appended objects from the second session.
    The following is just a simple test it's not actual code from the program I was talking about. Instead of objects containing different kind of information I'm using only strings here. To use the program use as arguments in the console "w" to create new file followed by the file name and the strings you want save to the file (as objects). Example: "+w TestFile.obj Thats Just A Test+". Then to read it use "r" (for reading), followed by the file name. Example "+r TestFile.obj+". As a result you'll see that all the strings that are saved in the file can be successfully read back. Then do the same: "+w TestFile.obj Thats Second Test+" and then read again "+r TestFile.obj+". What will happen is that the strings only from the first sessions will be read and the ones from the second session will not.
    I am sorry for making this that long but I couldn't explain it more simple. If someone can give me a solution I'll be happy to hear it! ^.^ I'll also be glad if someone propose different approach of the problem! Here is the code:
    import java.io.*;
    class Fio
         public static void main(String[] args)
              try
                   if (args[0].equals("w"))
                        FileOutputStream fos = new FileOutputStream(args[1], true);
                        ObjectOutputStream oos = new ObjectOutputStream(fos);
                        for (int i = 2; i < args.length ; i++)
                             oos.writeObject(args);
                        fos.close();
                   else if (args[0].equals("r"))
                        FileInputStream fis = new FileInputStream(args[1]);
                        ObjectInputStream ois = new ObjectInputStream(fis);
                        for (int i = 0; i < fis.available(); i++)
                             System.out.println((String)ois.readObject());
                        fis.close();
                   else
                        System.out.println("Wrong args!");
              catch (IndexOutOfBoundsException exc)
                   System.out.println("You must use \"w\" or \"r\" followed by the file name as args!");
              catch (IOException exc)
                   System.out.println("I/O exception appeard!");
              catch (ClassNotFoundException exc)
                   System.out.println("Can not find the needed class");

    How to read appended objects from file with ObjectInputStream? The short answer is you can't.
    The long answer is you can if you put some work into it. The general outline would be to create a file with a format that will allow the storage of multiple streams within it. If you use a RandomAccessFile, you can create a header containing the length. If you use streams, you'll have to use a block protocol. The reason for this is that I don't think ObjectInputStream is guaranteed to read the same number of bytes ObjectOutputStream writes to it (e.g., it could skip ending padding or such).
    Next, you'll need to create an object that can return more InputStream objects, one per stream written to the file.
    Not trivial, but that's how you'd do it.

    The following two links may help you to understand the other possibilities as well.

  • Reading little endian binary files

    Hi,
    Recently I tried to read from a little endian binary files. Here is the code:
    FileInputStream file_input = new FileInputStream (file);
    DataInputStream data_in = new DataInputStream (file_input );
    while (true) {
    try {
    short i_data = data_in.readShort ();
    catch (EOFException eof) {
    System.out.println ("End of File");
    break;
    System.out.println ( i_data );
    But I am getting wrong values (big-endian). I will be pleased if anyone can help me in this respect.

  • How do you open multiple binary files and plot them all on the same graph?

    I have three different binary files and I want to plot all 3 of them onto a graph.
    I am familiar with opening and reading a single binary file. (Thanks to the help examples!) 
    But to do multiple numbers at the same time?  I was thinking of putting 3 different 'reading from binary file' blocks with the rest of the 'prompts', 'data type', etc.. and then connecting them on the same wire.
    However, I got into a mess already when I tried to read one .bin file to dynamic data type --> spectral measurements --> graph waveform.  The error was Not enough memory to complete this operation...  Why is that?  That didnt happen in the help example "Read Binary File.vi"...  Has it got something to do with the dynamic data type?
    Thank you for your time.
    Jud~

    Have a look at the image below and attached VI.  Simply enter the different paths into the PathArray control.
