How to convert a String to an array

Can somebody tell me how to convert a String to an array

Can you not simply look at the API documentation? Nothing in the String API jumps out at you?

In your post you ask how to convert a string value to a date. The value returned from the Get-AdUser is already a date. It does not need to be converted.
Bill has sshown one way to convert a date to a string and there are other methods. You need to clarify your question.
If you are really trying ot convert strings to dates then you can start with this:
[datetime]'01/21/1965 13:33:23'
Most date strings aer autodetected by the class.

try
SimpleDateFormat sdfSource = new SimpleDateFormat("yyyy-MM-dd");
Date date = sdfSource.parse(strDate);
SimpleDateFormat sdfDestination = new SimpleDateFormat("yyyy-MM-dd ");

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 a String to an Icon

Hello,
I'm trying to figure out how to convert a String (specifically one letter) to an Icon for a JTree. The program I am working on uses .png files for the icons at the moment, with each .png being a single uppercase letter. However, recent discussion has us wanting to change to something more dynamic, since we anticipate needing new letters in the near future.
My task is to modify the current codebase so that the Icons used to identify nodes in the tree are created from a Font within code, rather than reading in .png files. I have done some experimenting with creating a Label with just that String, setting the font and trying to extract the image using calls like createImage(int width, int height) and so on, but so far to no avail.
If I could figure out how to at least convert the String to an image, I could probably make it work (since I can play around with creating an ImageIcon with that image). Thanks in advance for any help.
Allan

Here is some quick and dirty code:
import java.awt.*;
import javax.swing.*;
public class BasicIcon implements Icon {
    private String text;
    public BasicIcon(String text) {
        this.text = text;
    public int getIconWidth() {
        return 16;
    public int getIconHeight() {
        return 16;
    public void paintIcon(Component c, Graphics g, int x, int y) {
        Color old = g.getColor();
        g.setColor(c.getForeground());
        g.drawString(text, x, y+13);
        g.setColor(old);
    public static void main(String[] args) {
        JPanel cp = new JPanel();
        for (char ch = 'A'; ch < 'F'; ++ch) {
            cp.add(new JButton("letter " + ch, new BasicIcon(String.valueOf(ch))));
        JFrame f = new JFrame("BasicIcon");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setContentPane(cp);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
}One thing that could be improved is the vertical positioning of the letter in the Icon.
The x,y values passed into paintIcon are the upper-left hand corner of the icon,
but the y value needed by drawString is the position of the String's baseline.
To do it right, use one of Font's getLineMetrics methods and play around with ascent.

You are not reading temperature, you are reading a binary file. You seem to be assuming string format but do you really know? No one here can tell since you did not attach the file If it is you would need to use one of the string conversion functions. And please, get rid of the Data local variable. You are already usin shift registers. Do the same with the data from the file.

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();
}

Convert a string to an array of 16bit 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:

Are you sure Field1, Field2, Field4 and Field5 contain a number information in all rows?
If there is a non numeric String in your Field<x> columns in any row the error will occor.

[Oracle 8i] How to convert a string (time stamp) into a date?

I'm having difficulty figuring out how to convert a time stamp string into a date (or possibly a number).
The time stamp is 20 positions, character (NOT NULL, CHAR(20))
in the format: YYYYMMDDHHMMSSUUUUUU
where Y = Year, M = Month, D = Day, M = Minutes, S = Seconds, and U = Microseconds
The reason I want to convert this is so that I can compare one time stamp to another (i.e. I want to be able to find the MIN(timestamp), MAX(timestamp), and do inequality comparisons).
Is this at all possible?
Thanks in advance for help on this!

Hi,
As Damorgan said, if all you want to do is find which is the earliest or latest, then you can just compare the strings: they happen to be in a format where that works.
If you need to do other things, such as compare them to today's date, or see the difference between two of your rows in days, then you have to convert them to DATEs. (There's no point in converting them to NUMBERs).
A new data type, TIMESTAMP, which handles fractions of a second, was introduced in Oracle 9.
Since you're using Oracle 8 (according to your subject line), you either have to
(1) ignore the microseconds, or
(2) use a separate NUMBER column for the microseconds.
Either way, use TO_DATE to convert the first 14 characters to a DATE:
TO_DATE ( SUBSTR (txt, 1, 14)
, 'YYYYMMDDHH24MISS'
)where txt is your CHAR column.
To convert the microseconds to a number (between 0 and 999999):
TO_NUMBER (SUBSTR (txt, 15))
