    I'll give you the quick answer: you use Readers for character streams (e.g., text files) and InputStreams for binary streams (e.g., binary files).
    Still, read the tutorial. You will find out lots of useful info.

  • Creating Binary Files in Java

    Does anyone know how to create a binary file in Java.
    in C i can do an fopen("filename" , "rb") i cannot find a equivalent java binary file stream.
    Thanks

    The following code is part of my FileIO applet. This method allows the user to download any file from my server and save it on his/her disk, the download is accomplished by doing a byte-read and byte-write (byte mover as I'd call it). This example illustrates how you can read and write binary files in Java:
       public void aok_DownLoad(String inputFile, String outputFile) {
          try {
             URL url=new URL(inputFile);
             InputStream in;
             in=url.openStream();
             BufferedInputStream reader=new BufferedInputStream(in,4096);
             FileOutputStream out=new FileOutputStream(outputFile);
             BufferedOutputStream writer=new BufferedOutputStream(out,4096);
             byte[] buf=new byte[4096];
             int byteRead;
             while ((byteRead=reader.read(buf,0,4096))>=0) {writer.write(buf,0,byteRead);}
             reader.close();
             writer.flush();
             writer.close();
          catch (Throwable exception) {
             exception.printStackTrace();
       }V.V.

  • Binary files in java

    hi
    I am a bit new to java and am having some problems with binary files. What I need to do is search a binary file for any accurances of the data contained with in another set of binary files. I need to know if the first file contains any of the signatures in the set of files. any help would be great.
    thanks very much
    Colin

    you take your file, you read in some bytes and you loop thru those bytes to find matching bytes that you are looking for. Here's some cdoe that's probably not as elegant as it could be, but you get what you pay for.
    public static int indexOf(byte[] a, byte[] b) {
       return indexOf(a, b, 0);
    public static int indexOf(byte[] a, byte[] b, int start) {
       if(a == null || b == null || a.length == 0 || b.length == 0 || a.length < b.length) {
          return -1;
    outer:   for(int i = start; i < a.length-b.length; i++) {
          if(a[i] == b[0]) {
             for(int j = 0; j < b.length; j++) {
                if(a[i+j] != b[j]) {
                   break outer;
             return i;
    }

  • How does Java API handles binary files

    I couldn't find some documentation which describes how to extend the Java API for handling binary files. (I want to upload, check in/out (and delete) such files from within a Java application.) Does anybody know where I can find an example or some related documentation?
    TIA, Olaf

    The methods on ContentObjectDefinition
    allow you to create binary or ascii document content.

  • Need to create a function to receive binary files from Java WebDynpro

    Hey,
    I need to recieve files from java Webdynpro and save them as a file on the backend
    system. After that, the file will be loaded to the documentum.
    In a function module, I only can get the files as a String. Therefore (I think), I need the
    binary file as base64 encoded. Otherwise I can´t get it as a string.
    Now I need to decode it in the backend, but how? I know, there are HTTP-classes
    in newer system, but not in the 4.6C System, I have here.
    Any idea, how I can recieve the files in the function module and transfer it as binary
    file to the backend system?
    If I load a file from the gui with gui_upload, I get the binary file as an internal table
    and can transfer it to the backend filesystem now. Maybe I can get the binary file
    in this way in the function?
    Thank You for Your help!

  • 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 open and read binary files?

    How do I open and read Binary files?

    Did you  look on The Unarchiver's web site where it has a link to older versions? http://theunarchiver.googlecode.com/files/TheUnarchiver3.2_legacy.zip
    The best thing to do is ask your friends what programs they used to produce these files, or at least what format files they are producing.  Otherwise it's like being shown a car and given a bundle of 200 keys with no idea to which one to use, or even if any of them work with that car.
    Using The Unarchiver will likely not do anything because it too will not know what format files are involved, and they may not even been in an archived format.  If they sent you a Word file without telling you (a favorite of Windows users to do  -- it drives me crazy when they could have just sent them in plain text), The Unarchiver won't open them.  If it's a picture file then using Hexedit will just show you a bunch of unintelligible stuff as shown in an earlier post, though you may see a line of text providing a hint.
    As I said earlier, often .bin may be an executable program which needs another program to actually interpret it.  That's what Java is trying to do.  Still, it may think it can execute the file, but it is highly unlikely somebody would send you an executable program (and if they did I would not trust it).  For all you know it may be a Windows virus.

  • How can I convert the binary file content to XML message

    Dear friends,
    I poll the binary file from a ftp server but the payload only includes the binary content, no XML structure in the payload, I hope to convert the binary content to a element node within the XML structure, how can I do that? via content conversion?
    Thanks and regards,
    Bean

    Read the binary file stream using java I/O standard functions and convert the read stream to Base64 format. Now map this content to one of the field in target XML structure.
    You need a java mapping for this.
    what is your target system?
    Thanks,
    Gujjeti.
    Hi Gujjeti,
    Thanks a lot for your kind help, my target system is R/3.
    Can I achieve that with a UDF or a simple way?

  • How do I create a binary file using PL/SQL

    DBMS_LOB won't help you write a BLOB to disk.
    You need to an external procedure to do that. Eric K's java works great and he's helped me with his solution and probably about a thousand others.
    Doing a search on this forum will yield many discussions on this often regurgitated topic.

  • 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).
