Converting String to an Array

Hi..
Need some help on how to go about converting a given string into an array. I belive there is a way in java to chop the string into chars and then feed the chars into an array. Anyone that can help me out on what methods to look for?

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.

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.
Help would be appreciated.
Thanks,

Converting XML String to MessageElement array

Hi,
I am trying to call a .NET web service from my Java client. I used WSDL2Java to generate the java classes for calling the .NET web service. The generated classes to call the service expects an array of org.apache.axis.message.MessageElement objects. I have a string representing an XML document which looks like this:
String xmlString = "<Results><Adjustments><Adjustment><RebuildAdjustmentID>16</RebuildAdjustmentID><IsBasicAdjustment>true</IsBasicAdjustment><AdjustmentType>stone/AdjustmentType><Title>External walls</Title></Adjustment></Adjustments></Results>"
I have tried converting the string into an array of MessageElement objects by the following way:
MessageElement[] m = new MessageElement[1];
Document XMLDoc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader(result2.toString())));
m[0] = XMLDoc.getDocumentElement();
However I keep getting the following message returned from the service:
"Object reference not set to an instance of an object"
I have tried a handful of ways but keep getting this same error. I have searched the web for hours looking for a solution to this problem without success so any help/ideas much appreciated,
Thanks.

How to convert string containing comma seperated values to an array

my requirement is i have to first convert an comma seperated string to an array
after that i have to pass the array values to a for loop
eg:i have a string str=(456,457,487,465,478)
These values i have to put in an array.
i then i have to pass the array values to a for loop

We understand your ¿homeworks? We are helping you, but it seems like you want us to do it.
Try it yourself with some of the instructions.
Anyway if there aren´t homeworks, use dinamyc sql:
declare
varray := '(45,65,12,4)';
begin
execute immediate 'update table set ss=''uu'' where id in ' || varray;
end;

Converting String Array -- String

Hi All,
I am converting String array to string using the following code:
String[] a= ....;
StringBuffer result = new StringBuffer();
if (a.length > 0) {
result.append(a[0]);
for (int i=1; i<a.length; i++) {
result.append(a);
return result.toString();
Is there is any other easy or efficient way to convert rather than the above code ?
Thanks,
J.Kathir

It could have been written:
StringBuffer result = new StringBuffer();
for(int i=0; i<a.length; ++ i)
result.append(a);
return result.toString();
Or in 1.5 lingo
StringBuilder result = new StringBuilder(); //slightly less overhead
for(String s : a)
result.append(s);
return result.toString();If you aren't picky about the format of the resulting string,
you could use the java.utilArrays method )]toString(Object[]):
String[] array= {"Hello", "World", "this", "is", "a", "1.5", "method"};
String s = Arrays.toString(array); //[Hello, World, this, is, a, 1.5, method]

Convert a string to an array of 16bit unsigned integers

I have a string represented in hex format, how can I convert this to an array of 16 bit unsigned integers?
I know I can use string to byte array to easily convert it to 8 but unsigned integers, is there a simple way for 16 bit unsigned integers?

While your description is somewhat vague and not very clear, I think the typecast solution from the previous poster may not be what you look for. You may more likely look for something along these lines:

"converting strings into integers in a array"

I'm really left scrating my head trying to figure this out.
What I have right now is this
public class NameManager
     private names[] collection; // collection of names
     private int count;
     public NameManager() // Creating an array which for now is empty
          collection = new names[1000];
          count = 0;
          String [] collection = {"boston", "Springfield", "New Haven",
                    "New York", "Albany"};
Its a namemanager for my road trip project which will be sort of like mapquest. What it does, or it's supposed to do is I have a array of names of cities, that represented as strings, in a array called, collection. What my proffeser wants me to do is turn the strings into integers, so in this elements in the array can be referenced .
It's probably so easy that I'll want to kick myself when I find out how to do it , but for whatever reason , all the information have found on the internet seems to go right over
If any body can give some idea of how to turn the string you see above into a set of intege s I would be so grateful.

turn the string into the index in the array
i.e.
boston => 0
springfield => 1
New Haven => 2
New York => 3
Albany => 4I should've mention this before but I need the names to go along with the numbers.
This is the directions from my proffesser, I know it's not the easiest to understand
but hopefully It will give you a better idea of what I'm talking about.
A name manager. This object turns strings into numbers. Every time a name is added to the name manager, it is checked to see if it has already been seen. If so, return the number previously assigned to the name. If not, increment the "number of known names" and return this number as well as remember the string for future reference. You can assume that there will be no more than 1000 names in the manager. Each name is a string.
A city. A city is a simple object: the city has a name and a number (at present).
I got most of this part done it just strings integers part that's getting me.

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 do I convert a 1-D array of cluster of 5 elements into a 2-D array of numbers? (history data from a chart)

Hello,
in my vi I have a chart with 5 Plots displaying measurement data.
The user should be able to save all the history data from the chart at anytime. (e.g. the user watches the chart and some event happens, then he presses a "save"-button)
I know, that I can read out the history data with a property node. That is not the problem. The problem is, how do I handle the data? The type of the history data is a 1-D array of cluster of 5 elements.
I have to convert that data somehow into a 2 D-array of numbers or strings, so that I can easily save it in a text-file.
How do I convert a 1-D array of cluster of 5 elements into a 2-D array of numbers?

Gerd,
thank you for the quick response and the easy solution.
Look what I did in the meantime. I solved the problem too, but muuuch more complicate :-)
And I have converted the numbers to strings, so that I can easily write them into a spreasheet file.

Converting object wrapper type array into equivalent primary type array

Hi All!
My question is how to convert object wrapper type array into equivalent prime type array, e.g. Integer[] -> int[] or Float[] -> float[] etc.
Is sound like a trivial task however the problem is that I do not know the type I work with. To understand what I mean, please read the following code -
//Method signature
Object createArray( Class clazz, String value ) throws Exception;
//and usage should be as follows:
Object arr = createArray( Integer.class, "2%%3%%4" );
//"arr" will be passed as a parameter of a method again via reflection
public void compute( Object... args ) {
    a = (int[])args[0];
//or
Object arr = createArray( Double.class, "2%%3%%4" );
public void compute( Object... args ) {
    b = (double[])args[0];
//and the method implementation -
Object createArray( Class clazz, String value ) throws Exception {
     String[] split = value.split( "%%" );
     //create array, e.g. Integer[] or Double[] etc.
     Object[] o = (Object[])Array.newInstance( clazz, split.length );
     //fill the array with parsed values, on parse error exception will be thrown
     for (int i = 0; i < split.length; i++) {
          Method meth = clazz.getMethod( "valueOf", new Class[]{ String.class });
          o[i] = meth.invoke( null, new Object[]{ split[i] });
     //here convert Object[] to Object of type int[] or double[] etc...
     /* and return that object*/
     //NB!!! I want to avoid the following code:
     if( o instanceof Integer[] ) {
          int[] ar = new int[o.length];
          for (int i = 0; i < o.length; i++) {
               ar[i] = (Integer)o;
          return ar;
     } else if( o instanceof Double[] ) {
     //...repeat "else if" for all primary types... :(
     return null;
Unfortunately I was unable to find any useful method in Java API (I work with 1.5).
Did I make myself clear? :)
Thanks in advance,
Pavel Grigorenko

I think I've found the answer myself ;-)
Never thought I could use something like int.class or double.class,
so the next statement holds int[] q = (int[])Array.newInstance( int.class, 2 );
and the easy solution is the following -
Object primeArray = Array.newInstance( token.getPrimeClass(), split.length );
for (int j = 0; j < split.length; j++) {
     Method meth = clazz.getMethod( "valueOf", new Class[]{ String.class });
     Object val = meth.invoke( null, new Object[]{ split[j] });
     Array.set( primeArray, j, val );
}where "token.getPrimeClass()" return appropriate Class, i.e. int.class, float.class etc.

Creating a String from an array of characters.

Hi,
i'm trying to make a string from an array of characters, this i've managed:
char data[] = new char[x];
String str = new String(data);My problem is this: Let's say the array of characters has space for 10 chars, but i only input 5, when i convert it to a string, the 5 characters show up fine, but the last remaining characters show up as little boxes ( [] [] [] [] [] ) .
It there a way to remove these?
Thanks in advance

When you say "string of numbers" do you mean an array? What is the specific issue you are having? You seem to have orange wires running all over the place. Give a small example demonstrating the problem.
