Casing Strings to string[] array

Hi,
Beginner question.
Why can i do this:
String[] tmp = {"mike", "Bob", "Jay"};
SomeClass.main(tmp);
But i can't do this:
SomeClass.main({"mike", "Bob", "Jay"});
It does not make sense to me.
It would save me some time if i didn't have to declare a String[] all the time.
Thanks,
-J

The Syntax {"a", "b", "c"} is an array initializer and it can't be used like an array literal. Here are two solutions:
public class Example {
    public static void main(String[] args) {
        f(new String[]{"a", "b", "c"});
        g("a", "b", "c");
    static void f(String[] v) {
        for(int i=0; i<v.length; ++i) {
            System.out.println(v);
static void g(String... v) {
for(int i=0; i<v.length; ++i) {
System.out.println(v[i]);
} [The String... syntax is a vararg|http://java.sun.com/j2se/1.5.0/docs/guide/language/varargs.html]

The code that you pasted does not seem like written by a beginner. So, did you write the code?
If so, you should have no problem solving this simple thing.
If not, then copy and pasting a block of program that you don't understand will keep you as a beginner all the time, so can't help you if you are willing to stay at beginner.

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();
}

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.

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.

Compare two strings in an array

Hello!
Please feel free to give me hints, but do not give me any code.
Ok, here is what I am trying to do, I whant to compare my input string whith strings allready stored in the array. If my input string equals any of the allready excisting strings, a error wil show upp, otherwise store the new string in next avalibal position. I do not seem to get the method right for comparing the strings. here is the method I have written so far, please take a look and give me a hint, but no code. :)
//Check if a user already excists
public void compareNames (People in_array [], String in_name) {
          for (int i=0; i<value.peopleCount; i++) {
               if (in_name.equals(in_array.getPeople())) {
               System.out.print("The user already excist, please chose another name");
}value.peopleCount is an global count value for people arays.
getPeople get the name from the people class.
Martin

A couple notes here.
The name compareNames() is misleading if it is going to do what you described. A comparison will generally not have side-effects like outputting error messages to the console or adding new items to an array. It would be better if you called the method addIfNew(), and returned a boolean indicating whether the name was new or not. The caller would then be responsible for displaying an error message if the method returned false.
I also suggest you use a List such as ArrayList instead of an array, otherwise you will have to resize and copy your array every time you add something to it that exceeds the array size, and will allow you to do away with the global peopleCount.

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

Changing an Array of Strings to an Array of Double or Int

How would I change a string of arrays to ints or doubles...here my code:
     File inputFile = new File("testing");
        FileReader in = new FileReader(inputFile);
     BufferedReader bufin = new BufferedReader(in);
     String c;
     String[] x = new String[300];
     String[] Xcoord = new String[300];
     String[] Ycoord = new String[300];
     int counter = 1;
            while ((c = bufin.readLine()) != null)
          if( counter >= 3 )
               x[counter] = c;
               String[] xySplit = x[counter].split(" ");
               System.out.println("X: "+xySplit[0]+" Y: "+xySplit[2]);
               Xcoord[counter] = xySplit[0];
               Ycoord[counter] = xySplit[2];
           in.close();

Use a parsing method:int i = Integer.parseInt (s);
double d = Double.parseDouble (s);>> String[] x = new String[300];
You seem like you want to use a list instead.

Help with String/ and or Array loading and comparing

Hi all,
I'm having some problems with trying to find the best way to achieve the following on a Poker Dealing program. I randomly shuffle a 52 card deck of playing cards and deal out 5 cards. Cool...
Now I have to go back thru the String and determine if my hand of cards contains
a pair
2 pair
3 of a kind
Full House
etc etc
I am trying to do String comparisons (there is an empty compareCards method in my code right now, but I'm getting a bit frustrated as to find the best way to do it... Would an array load in a separate method be a better way???? What I need to do is after I load my hand , is to display a message stating a pair, 3 of a kind , etc etc.....
Thanks in advance

You could have the original face values as integers, thus Ace = 1, Jack = 11 (it'll be easy enough to display the proper values AJQK if you keep your string array and just display whatever corresponds to the value held in your int array).
Each player gets an array of five cards. You could the loop through each hand and increment values held in another array by one according to the value of the card. Haven't coded the following up but it should work I think.
// hand [ ] represents the cards held by that player
int handChecker [ ] = new int [14]
for (int counter = 0; counter < 5; ++ counter)
// 1st card is an Ace. handChecker [1] will be incrementd by one and so on
// 2nd card is a 9. handChecker[9] will be incremented by one.
handChecker[hand[counter]] += 1;
// Loop through the array handChecker to find pairs etc.
boolean pair = false;
bollean tofk = false;
for (int counter = 1; counter < 14; ++ counter)
if (handChecker[counter] == 2)
pair = true;
if (handChecker[counter] == 3)
tofk = true;
if (pair)
// player has a pair
if(tofk)
// player has three of a kind
if(pair && tofk)
// player has a full house

How to break up a String into multiple array Strings?

How do I break up a string into a bunch of String arrays after the line ends.
For example,
JTextArea area = new JTextArea();
this is a string that i have entered in the area declared above
now here is another sting that is in the same string/text area
this is all being placed in one text field
Sting input = area.getText();
now how do I break that up into an array of strings after each line ends?

Ok I tested it out and it works.
So for future refrence to those that come by the same problem I had:
To split up a string when using a textfield or textarea so that you can store seperate sections of the string based on sperate lines, using the following code:
String text = area.getText() ;
String[] lines = text.split("\n") ;
This will store the following
this is all one
entered string
into two arrays

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.
