Converting a byte array into int

Here's my problem, I've read my data from a server into a byte array.
the array is 12 elements in length representing three int variables.
int flag;
int query_a;
int query_b;
here's what i receive:
0 0 0 0 34 0 0 -2 21 0 0 0
how do i convert these into the int values i need.
i know the first four are for flag = 0, but how does it convert?
0000 = 0 for each byte
00000000 00000000 00000000 00000000 = 0 for each bit?
or is there a method to convert from a byte to int?

Look at the ByteBuffer class (part of 1.4.1) - before that, you would have had to manually build your integers using left shift and & operator (not that big of a deal, really).
Be sure you know the "Endian"-ness of the platform you are reading data from though, otherwise, your ints will not be what you expect!

  • How to convert String array into int.

    how do i convert words which is a string array into int type. i kno string can be converted into int using interger.parseint. but wat abt string arrays??? plz help me out with the above code.

    i did tht its still giving the same errorFor Heaven's sake, what about taking a second to try to understand the code you're copying first? If you really can't fix the error yourself, you have a more serious problem than just convertingStrings to ints.
    And if you want { "1", "2", "3" } to be 123:
    StringBuffer b = new StringBuffer();
    for (int i = 0; i < array.length; i++) {
      b.append(array);
    int result = Integer.parseIn(b.toString());

  • Convertion of byte array in UTF-8 to GSM character set.

    I want to convert byte array in UTF-8 to GSM character set. Please advice How can I do that?

    String s = new String(byteArrayInUTF8,"utf-8");This will convert your byte array to a Java UNICODE UTF-16 encoded String on the assumption that the byte array represents characters encoded as utf-8.
    I don't understand what GSM characters are so someone else will have to help you with the second part.

    can you help me to find out how to convert a hex representaion of key int DES key object

    hi friend,
    I think the key size is more than the required size. For DES algorithm, the key size is 64 bit long.But the code u have given has more than 64 bit, because of which this exception has been raised.
    Reduce the key value to 64bit and try. If it doesnt work,try the code given below .I think it might be helpful for u

  • Converting a byte[] to a int or a Point

    I have sent a DatagramPacket containing a Point object converted to a byte[]. Now I want to convert the byte[] object back to a Point object. How do I do it?
    In my application I want to draw a number of dots in a window, send to a copy of the application in some other location on the Net and the two applications must view the same dots in real time. So I thought I would draw the dots, send the cordinats in a Datagram and then draw the dots using this cordinats. Is that a good idea?
    Best regards
    Jonas

    To create a Point from a byte[], assuming the byte[] has two elements:
    Point p = new Point((int)byte[0], (int)byte[1]);Is that what you need?

  • How can I convert a U32 array into binary string?

    I would like to find an efficient way to convert an array of 8192 U32 into a single binary string!!!
    the solution below  last 550 ms on an RT target to convert 8192 U32.
    The same code running on Labview (not RT) last 100ms. I don't understand why there is such a difference.
    I've tryed to replace the inner loop and convert by a format string whith U32 on entry and %032b as parameter but it lasted same time.
    Thanks a lot

    Your picture of your code didn't come through. You can't link to a picture that's on your computer, as a server on the internet cannot access your computer to display the picture for others to see. You have to upload the picture as an attachment. Then, if you want to actually display the picture in the message you have to edit your post, insert a picture, and when it asks for the URL you enter the URL of the picture. You can get the URL when viewing the message, as the link is within the message itself.
    As for your question, can you just use the TypeCast function?

  • Reading in any file and converting to a byte array

    Okay what I am trying to do is to write a program that will read in any file and convert it into a int array so that I can then manipulate the values of the int array and then re-write the file. Once I get the file into an int array I want to try and compress the data with my own algorithm as well as try to write my own encryption algorithm.
    What I have been looking for is code samples that essentially read in the file as a byte array and then I have been trying to convert that byte array into an int array which I could then manipulate. So does anyone have any sample code that essentially takes a file and converts it into an int array and then converts it back into a byte array and write the file. I have found code that is close but I guess I am just too new to this. Any help would be appreciated.

    You can read a whole file into a byte array like this:File f = new File("somefile");
    int size = (int) f.length();
    byte[] contents = new byte[size];
    DataInputStream in = new DataInputStream(
                              new BufferedInputStream(new FileInputStream(f)));
    in.readFully(contents);
    in.close();Note that you need to add in the proper exception handling code. You could also use RandomAccessFile instead of the DataInputStream.
    Writing a byte array to a file is easier; just construct the FileOutputStream, call write on it with the byte array, and close the stream.

  • Byte array to base64encoder problem, cannot encode a 7.7 MB file

    hey guys, so ive been trying to use the base64encoder to encode a bytearray which is then sent thru a webservice to the server to be decoded.
    and as the subject of this post suggests, i have been having problems encoding a big file,
    forexample i tried to upload/convert a 84KB image and it worked just fine... the trace of the string ended with a "==" which i believe means that the conversion is complete...
    but when i try to upload a 7.7MB image, it is, i guess, crashing... i dont see any "==" in the string... so i guess its not working... i was wondering if there is any any type of file size limit or soemthign for the encoding...

  • Byte Array from SQL Reporting Service

    I am calling the Render method of the Microsoft SQL Reporting
    Service's ReportExecution web service. It returns a Byte array in
    the lastResult object. I am having the hardest time figuring out a
    way to convert that byte array into something I can use in Flex.
    The byte array, once converted into a more user friendly format,
    will contain the rendered version of a SQL Report in whatever
    format I have specified...in this case it is XML. Any input or
    suggestions would be appreciated.

    This is a little late, I know. but I just spent the day
    struggling with this very issue. Hopefully this can help someone
    else in the future. Here's my solution...
    on MX:Operation -- result="fillXML()"
    then
    private function fillXML(): void {
    var x:XML = new
    XML(wsProps.GetDatasetData.lastResult.toString());
    ...do what you need with your xml...
    I use an XMLList node of the result as the source property
    for an XMLListCollection bound to a datagrid. Let me know if you
    need more help to get it working. It works like a charm now that I
    figured that out. I don't know if it's a slimy hack, or not, but it
    gets the job done.

  • How do I read directly from file into byte array

    I am reading an image from a file into a BuffertedImage then writing it out again into an array of bytes which I store and use later on in the program. Currently Im doing this in two stages is there a way to do it it one go to speed things up.
    try
                //Read File Contents into a Buffered Image
                /** BUG 4705399: There was a problem with some jpegs taking ages to load turns out to be
                 * (at least partially) a problem with non-standard colour models, which is why we set the
                 * destination colour model. The side effect should be standard colour model in subsequent reading.
                BufferedImage bi = null;
                ImageReader ir = null;
                ImageInputStream stream =  ImageIO.createImageInputStream(new File(path));
                final Iterator i = ImageIO.getImageReaders(stream);
                if (i.hasNext())
                    ir = (ImageReader) i.next();
                    ir.setInput(stream);
                    ImageReadParam param = ir.getDefaultReadParam();
                    ImageTypeSpecifier typeToUse = null;
                    for (Iterator i2 = ir.getImageTypes(0); i2.hasNext();)
                        ImageTypeSpecifier type = (ImageTypeSpecifier) i2.next();
                        if (type.getColorModel().getColorSpace().isCS_sRGB())
                            typeToUse = type;
                    if (typeToUse != null)
                        param.setDestinationType(typeToUse);
                    bi = ir.read(0, param);
                    //ir.dispose(); seem to reference this in write
                    //stream.close();
                //Write Buffered Image to Byte ArrayOutput Stream
                if (bi != null)
                    //Convert to byte array
                    final ByteArrayOutputStream output = new ByteArrayOutputStream();
                    //Try and find corresponding writer for reader but if not possible
                    //we use JPG (which is always installed) instead.
                    final ImageWriter iw = ImageIO.getImageWriter(ir);
                    if (iw != null)
                        if (ImageIO.write(bi, ir.getFormatName(), new DataOutputStream(output)) == false)
                            MainWindow.logger.warning("Unable to Write Image");
                    else
                        if (ImageIO.write(bi, "JPG", new DataOutputStream(output)) == false)
                            MainWindow.logger.warning("Warning Unable to Write Image as JPEG");
                    //Add to image list
                    final byte[] imageData = output.toByteArray();
                    Images.addImage(imageData);
                  

    If you don't need to manipulate the image in any way I would suggest you just read the image file directly into a byte array (without ImageReader) and then create the BufferedImage from that byte array.
