Converting String to byte array

Hi,
There is a code for converting String to byte array, as follows:
     public byte[] toByteArray(String s)
          char[] c = s.toCharArray();
          int len = c.length;
          byte[] b = new byte[len * 2];
for ( int i = 0 ; i < len ; i++ )
     b[i * 2] = (byte)(c);
     b[(i * 2) + 1] = (byte)(c[i] >> 8);
return b;
But this isn't doing the conversion properly. For example, for the � (euro) symbol, it converts to some other unreadable symbol. Also, same is the case for square brackets. Any idea why this' so? What's wrong with the above code?
The encoding format is UTF-8.
Thanks.

> In fact, I tried with String.getBytes() too, but leads to the same problem, with those specific symbols.
Did you try the String.getBytes(String charsetName) method?
Both methods have been around since Java 1.1.
It's an extremely important skill to learn to read the API and become familiar with the tools you will use to program Java. Java has an extensive set of online documentation that you can even download for your convenience. These "javadocs" are indexed and categorized so you can quickly look up any class or method. Take the time to consult this resource whenever you have a question - you'll find they typically contain very detailed descriptions and possibly some code examples.

How to get a string or byte array representation of an Image/BufferedImage?

I have a java.awt.Image object that I want to transfer to a server application (.NET) through a http post request.
To do that I would like to encode the Image to jpeg format and convert it to a string or byte array to be able to send it in a way that the receiver application (.NET) could handle. So, I've tried to do like this.
private void send(Image image) {
    int width = image.getWidth(null);
    int height = image.getHeight(null);
    try {
        BufferedImage buffImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        ImageIcon imageIcon = new ImageIcon(image);
        ImageObserver observer = imageIcon.getImageObserver();
        buffImage.getGraphics().setColor(new Color(255, 255, 255));
        buffImage.getGraphics().fillRect(0, 0, width, height);
        buffImage.getGraphics().drawImage(imageIcon.getImage(), 0, 0, observer);
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        JPEGImageEncoder jpeg = JPEGCodec.createJPEGEncoder(stream);
        jpeg.encode(buffImage);
        URL url = new URL(/* my url... */);
        URLConnection connection = url.openConnection();
        String boundary = "--------" + Long.toHexString(System.currentTimeMillis());
        connection.setRequestProperty("method", "POST");
        connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
        String output = "--" + boundary + "\r\n"
                      + "Content-Disposition: form-data; name=\"myImage\"; filename=\"myFilename.jpg\"\r\n"
                      + "Content-Type: image/jpeg\r\n"
                      + "Content-Transfer-Encoding: base64\r\n\r\n"
                      + new String(stream.toByteArray())
                      + "\r\n--" + boundary + "--\r\n";
        connection.setDoOutput(true);
        connection.getOutputStream().write(output.getBytes());
        connection.connect();
    } catch {
}This code works, but the image I get when I save it from the receiver application is distorted. The width and height is correct, but the content and colors are really weird. I tried to set different image types (first line inside the try-block), and this gave me different distorsions, but no image type gave me the correct image.
Maybe I should say that I can display the original Image object on screen correctly.
I also realized that the Image object is an instance of BufferedImage, so I thought I could skip the first six lines inside the try-block, but that doesn't help. This way I don't have to set the image type in the constructor, but the result still is color distorted.
Any ideas on how to get from an Image/BufferedImage to a string or byte array representation of the image in jpeg format?

Here you go:
private static void send(BufferedImage image) throws Exception
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    ImageIO.write(image, "jpeg", byteArrayOutputStream);
    byte[] imageByteArray = byteArrayOutputStream.toByteArray();
    URL url = new URL("http://<host>:<port>");
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    OutputStream outputStream = connection.getOutputStream();
    outputStream.write(imageByteArray, 0, imageByteArray.length);
    outputStream.close();
    connection.connect();
    // alternative to connect is to get & close the input stream
    // connection.getInputStream().close();
}

How can i convert object to byte array very*100 fast?

i need to transfer a object by datagram packet in embeded system.
i make a code fallowing sequence.
1) convert object to byte array ( i append object attribute to byte[] sequencailly )
2) send the byte array by datagram packet ( by JNI )
but, it's not satisfied my requirement.
it must be finished in 1ms.
but, converting is spending 2ms.
network speed is not bottleneck. ( transfer time is 0.3ms and packet size is 4096 bytes )
Using ObjectOutputStream is very slow, so i'm using this way.
is there antoher way? or how can i improve?

thanks a lot for your reply.
now, i use udp socket for communication, but, i must use hardware pci communication later.
so, i wrap the communication logic to use jni.
for convert a object to byte array,
i used ObjectInputStream before, but it was so slow.
so, i change the implementation to use byte array directly, like ByteBuffer.
ex)
public class ByteArrayHelper {
private byte[] buf = new byte[1024];
int idx = 0;
public void putInt(int val){
buf[idx++] = (byte)(val & 0xff);
buf[idx++] = (byte)((val>>8) & 0xff);
buf[idx++] = (byte)((val>>16) & 0xff);
buf[idx++] = (byte)((val>>24) & 0xff);
public void putDouble(double val){ .... }
public void putFloat(float val){ ... }
public byte[] toByteArray(){ return this.buf; }
public class PacketData {
priavte int a;
private int b;
public byte[] getByteArray(){
ByteArrayHelper helper = new ByteArrayHelper();
helper.putInt(a);
helper.putInt(b);
return helper.toByteArray();
but, it's not enough.
is there another way to send a object data?
in java language, i can't access memory directly.
in c language, if i use struct, i can send struct data to copy memory by socket and it's very fast.

Converting ASCII text (byte array ending in null) to a String

Hi all,
I am trying to convert a null terminated ascii string stored in a byte array to a java String. When I pass the byte array to the String constructor it
does not detect/interpret the null as a terminator for the ascii string. Is this something I have to manually program in? ie Check for where the null is and then
pass that subarray of everything before the null to the String constructor?
example of problem
// A B C D null F (note F is junk in the array, and should be ignored since it is after null)
byte[] asciiArray = { 65, 66, 67, 68, 0, 70 };
System.out.println(new String(asciiArray, "UTF-8"));
//this prints ABCD"sqare icon"F

Why do you expect the null character to terminate the string? If you come from a C or C++ background, you need to understand that java.lang.String is not just a mere character array. It's a full-fledged Java object that knows its length without having any need for null terminator. So Ascii 0 is just another character for String object. To achieve what you want to do, you have to manually loop through the byte array and stop when you encounter a null character.

Converting Image to Byte Array and then to String

Hi All...
Can anyone please help me. I have got a problem while converting a Byte array of BufferedImage to String.
This is my code, First i convert a BufferedImage to a byte array using ImageIO.wirte
public String dirName="C:\\image";
ByteArrayOutputStream baos=new ByteArrayOutputStream(1000);
BufferedImage img=ImageIO.read(new File(dirName,"red.jpg"));
ImageIO.write(img, "jpg", baos);
baos.flush();
byte[] resultimage=baos.toByteArray();
baos.close();
Then i tried to convert this byte array to a string
String str=new String(resultimage);
byte[] b=str.getBytes();
This much worked fine. But when i reversed this process to re-create the image from that string. i found the image distroted.
BufferedImage imag=ImageIO.read(new ByteArrayInputStream(b));
ImageIO.write(imag, "jpg", new File(dirName,"snap.jpg"));
I got this snap.jpg as distroted.
Please help me i have to convert the image to a string and again i have to re-create the image from that string.

To conver the bytearray to string use base64.encoding
String base64String= Base64.encode(baos.toByteArray());
To convert back use Base64.decode;
byte[] bytearray = Base64.decode(base64String);
BufferedImage imag=ImageIO.read(bytearray);

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.

How can I convert AudioInputStream to byte array ?

Hi
I want to convert audioinputStream to bytearry?
i try like this
ByteArrayOutputStream baos = new ByteArrayOutputStream();
     int c = 0;
     while (true) {
     try {
                    c = audioInputStream.read();
               } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
     if (c == -1)
     break;
     baos.write(c);
but...
java.io.IOException: cannot read a single byte if frame size != 1
occur...
plz help me..

Hi,
I haven't tried, but from the API doc I would suggest:
Retrieve the frame size by
int fs = audioInputStream.getFormat().getFrameSize();Allocate a byte array with at least this size and read full frames:
byte[] buf = new byte[fs];
int sz = audioInputStream.read(buf);Write also to your baos a full frame:
baos.write(buf, 0, sz);

From MD5-string to byte array

Hi fellows, I'm writing a simple cracker for MD5. The hash value has to be passed at command line as argument.
e.g.
java Cracker 0cc175b9c0f1b6a831c399e269772661In order to decode the hash value I'm using a brute force approach: therefore I compare a series of strings with the hash value by using the method of the class MessageDigest isEqual(byte[] a, byte[] b). So I encode each string and compare the byte array I get with the byte array of the hash value.
Here it comes the trouble I'm in:
when I try to get a bytes array of the MD5 hash value passed as argument of the program , I do get something, but it's not something that the isEqual method of MessageDigest can use to compare. As a result any attempt during the execution of brute force fails, even though the key is one of the string being checked.
Perhaps am I facing a format problem? Any idea?
Sorry for my english, it's not my first language
Thanks to whoever will help

Almost all questions in these forums about brute force attack on MD5 (or SHA1 or SHA256 etc etc etc) are school, college or university projects and of no practical use. This is almost certainly such a project.
Unless things have changed in the last year, there is no practical brute force attack on MD5 whereby an input can be generated from an arbitrary output even though two inputs with the same output can be fabricated. A dictionary attack is feasible if no salt is used or a known salt is used since one only has to build the dictionary for one salt value. If a different salt is used for each entry being attacked then a dictionary will be need for each salt being used. Of course if one takes the simple precaution of not using anything that is likely to be in a dictionary then the dictionary attack will likely fail.

Converting image into byte array

Hi all,
How to convert an integer array image into byte array ?
here i have a image like this :
private static int pixelArray[] = {
0xff000000, 0xff000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000,
0xff000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000, 0x00000000
From this one i create image like this one :
Image image = Image.createRGBImage(pixelArray, width, height, true);
Now i want to convert that pixelArray into byte array ? how to do this
additionally i want to send this byte array to servlet .
thanks in advance.

Hi,
If you want to convert your int array to a byte array you should
split each integer into 4 bytes to avoid losing information. You can
rebuild your integer array later if you need to. I think this code
will work (i havent tested it):
byte[] pixel= new byte[pixelArray.length<< 2];
for (int i= pixelArray.length- 1; i>= 0; i--) {
int aux= i<< 2; // i* 4 = i<< 2
pixel[aux]= (byte) (pixelArray>> 32);
pixel[aux+ 1]= (byte) (pixelArray[i]>>> 16);
pixel[aux+ 2]= (byte) (pixelArray[i]>>> 8);
pixel[aux+ 3]= (byte) pixelArray[i];
Greets.

Need help in converting string to numeric array

I am trying to convert a string to a numeric array ... the first # in the string gets cut off, the last three seem to come through.
This may be fairly simple, but I really haven't worked with the string functions all that much.

What is the best way to convert a cluster into byte array or string

I'm writing a program that sends UDP packets and I've defined the data I want to send via large clusters (with u8/u16/u32 numbers, u8/u16/u32 arrays, and nested clusters). Right before sending the data, I need to convert the clusters either into strings or byte arrays. The flatten to string function is almost perfect for this purpose. However, it's appending lengths to arrays and strings which renders this method useless, as far as I can tell.
As I have many of these clusters, I would rather not hard code the unbundle by names and converting/typecasting to byte arrays or strings for each one.
Is there a feature or tool I am overlooking?
Thank you!

deceased wrote:
Flatten to string has a boolean input of "Prepend string or array size" ... The default value is true.
That only specifies if a string or array size should be prepended if the outermost data element is a string or array. For embedded strings or arrays it has no influence. This is needed for the Unflatten to be able to reconstruct the size of the embedded strings and arrays.
The choice to represent the "Strings" (and Arrays) in the external protocol to LabVIEW strings (and arrays) is actually a pretty bad one unless there is some other element in the cluster that does define the length of the string. An external protocol always needs some means to determine how long the embedded string or array would be in order to decode the subsequent elements that follow correctly.
Possible choices here are therefore:
1) some explicit length in the protocol (usually prepended to the actual string or array)
2) a terminating NULL character for strings, (not very friendly for reliable protocol parsing)
3) A fixed size array or string
For number 1) and 2) you would always need to do some special processing unless the protocol happens to use explicitedly 32 bit integer length indicators directly prepended before the variable sized that.
For number 3) the best representation in LabVIEW is actually a cluster with as many elements inside as the fixed size.

String to Byte convertion related question. SMS related

Hi all
I need to ask more indepth question regarding string to bytes convertion. I need to have a constructed message format with a length of 161 bytes. Here's are the details:-
String message - 160 bytes allocation.
Message length - 1 byte allocation.
For converting the message string into byte I can use
byte b1[] = message.getBytes();
And i know to get the length of the message I can just use
message.length();
So my questions are :-
1) I need some help on how i'm supposed to convert the length message values and assign it into the message length variables which have 1 byte allocation.
2) Besides text, the message string can also be a hex value data. Hence it it possible that I can convert the hex data into byte and still maintain within the 160 bytes allocation ? Coz most of the times the hex data length will be > 160 but < 255 characters length. example :-
06050415810000024a3a7d35bd35bdb995e535bd41c9bd89b194040082986417614819817624e3105d85206605e09390391394417817817819817824e40e44e5104a04a04a05205105d85206605d8938c417614819817824e40e44e5105e05e05e06605e093903913944128128128148146800
Anyone can help ?
Thank You in Advanced

First of all. One character in a string can occupie
more than one byte in the destination array, so
String.length can be != bytes.length.
A byte in java is always signed, so the value will be
in the range -128 to +127.
KajHi Kaj,
Since you put it in that way, is there any tips u can give me on how I'm supposed to calculate the length of the string and set the value in byte ?
Or do I need to convert the string into bytes array first and then get the length ?
Thanks

Convert a string to an array of 16bit unsigned integers

How Do I Load An Animated GIF Into PictureBox Control From Byte Array?

I'm having a problem with loading an animated GIF int a picturebox control in a C# program after it has been converted to a base64 string, then converted to a byte array, then written to binary, then converted to a base64 string again, then converted to
a byte array, then loaded into a memory stream and finally into a picturebox control.
Here's the step-by-step code I've written:
1. First I open an animated GIF from a file and load it directly into a picturebox control. It animates just fine.
2. Next I convert the image in the picturebox control (pbTitlePageImage) to a base64 string as shown in the code below:
                if (pbTitlePageImage.Image != null)
                    string Image2BConverted;
                    using (Bitmap bm = new Bitmap(pbTitlePageImage.Image))
                        using (MemoryStream ms = new MemoryStream())
                            bm.Save(ms, ImageFormat.Jpeg);
                            Image2BConverted = Convert.ToBase64String(ms.ToArray());
                            GameInfo.TitlePageImage = Image2BConverted;
                            ms.Close();
                            GameInfo.TitlePageImagePresent = true;
                            ProjectNeedsSaving = true;
3. Then I write the base64 string to a binary file using FileStream and BinaryWriter.
4. Next I get the image from the binary file using FileStream and BinaryReader and assign it to a string variable. It is now a base64 string again.
5. Next I load the base64 string into a byte array, then I load it into StreamReader and finally into the picturebox control (pbGameImages) as shown in the code below:
byte[] TitlePageImageBuffer = Convert.FromBase64String(GameInfo.TitlePageImage);
                        MemoryStream memTitlePageImageStream = new MemoryStream(TitlePageImageBuffer, 0, TitlePageImageBuffer.Length);
                        memTitlePageImageStream.Write(TitlePageImageBuffer, 0, TitlePageImageBuffer.Length);
                        memTitlePageImageStream.Position = 0;
                        pbGameImages.Image = Image.FromStream(memTitlePageImageStream, true);
                        memTitlePageImageStream.Close();
                        memTitlePageImageStream = null;
                        TitlePageImageBuffer = null;
This step-by-step will work with all image file types except animated GIFs (standard GIFs work fine). It looks like it's just taking one frame from the animation and loading it into the picturebox. I need to be able to load the entire animation. Does any of
the code above cause the animation to be lost? Any ideas?

There is an ImageAnimator so you may not need to use byte array instead.
