Converting a string to a byte

I need to know how to convert a string of 1s and 0s into a byte.
For example, if the string were "10010001", how would I make it a byte?
I looked at the API, and the Byte class doesn't seem to have the capability to do this.
(I realize that this is probably an unconventional way of doing it, but I'm required to do it this way.)
Thanks in advance.

Okay, I realized why I was having trouble.
I even tried the parse method with the radix parameter thing before and it didn't work, but that was because I was using an invalid bit. (11001001)
That bit came from a randomly (well, pseudo-randomly) generated bunch of bits, so I just assumed that it would be good.
The project I'm working on is a one-time pad cipher, and that bit was generated by a method given to me by the professor. I remember now that he mentioned in passing something about how in this case, the first bit is used as a "sign bit" and that a "1" represents negative.
Sorry for wasting your time / frustrating you. Thanks for your help though.

  • Help with Sample on Converting an XML string to a byte stream

    Hello All,<br /><br />I am sure this is something simple, but I am just not figuring it out right now.<br /><br />I am following the sample - "Converting an XML string to a byte stream" from the developer guide since I want to prepopulate just 1 field in my PDF form.<br /><br />How do I reference my form field within my servlet code properly??<br /><br />I have tried a few things now, my field is within a subform, so I thought it would be <root><subformName><fieldname>My data</fieldname></subformName></root>  I have also tried adding <page1> in there too.<br /><br />I am following everything else exactly as given in the sample code.<br /><br />I do have an embedded schema within the form and the field is bound.<br /><br />Thanks,<br />Jennifer

    Well, if you have a schema defined in the form, then the hierarchy of your data must match what is described in the schema. So, can't really tell you what it would look like, but just follow your schema.

  • I want to convert a String into an array of bytes

    I am working with telnet programming with java, where I want to convert login name and password of an online user in 'String' format to 'Bytes', plz help me. Which Input or Output Stream I can use

    Assuming you've got the username / password into a String object, you can convert it to a byte[] array using this method.
    String.getBytes();
    Look at the String API

  • Is it possible to convert from string to variant?

    Hi!
    I would like to convert a text string to variant. I'm doing this because I would like to merge a couple of signals and then save all the signals in a lvm-file. Could someone please explain how to convert from text to variant, is it possible?
    Thanks in advance!

    What you are attempting to do is possible, but might not give you the results you expect.  All you need to do is convert your string to an array of U8s using the String to Byte Array conversion primitive.  In the file, you will get a single character per line of the file expressed as the ASCII code.  When you read it, convert to U8s, then use Byte Array to String to get your string back.
    You may also want to read up on LVM files.  There are several places to put strings that work a little better than this.

  • How can I convert a string of hex values to a hex format string programatically?

    Is there a way to convert a string of the following format:

    You can iterate over the string and use the String to Hex VI. If you work with two bytes of the string at a time you can get a U8 array of the desired binary values. Then when you are complete you can either work with the byte array of convert it back to a string using Byte Array to String.

  • Convert C string in to BSTR with CA_CString​ToBSTR()

    I want to convert C string in to BSTR format with function CA_CStringToBSTR.
    I call an ActiveX function. In this function is CA_CStringToBSTR called.
    ------------ActiveX Function ---------------------
    HRESULT state;
    char buf[50]="0.0";
    BSTR bstr=0;
    state = CA_CStringToBSTR(buf, &bstr);
    return ......;(0x80070057 error code "Wrong parameter")
    Debuger after this Fun gives me the following result: state=0, bstr=0xXXXX(48)(No size Info)   [48=0x30='0']
    Then I get error from this ActiveX function. I think the problem is here with this CA-CStrng..... Function.
    Is that correct, what does this function? 

    You should never send C structs over the wire, otherwise you are expecting the other end to know (a) the source machine's byte order (b) the source machine's C compiler's alignment and padding rules (c) the source machine's C compiler's options in effect for the compilation of the program some of which can affect (b).
    Instead you should write each field separately in network byte order using htons(), htonl(), &c, or use something like XDR. If you do the former make sure the output is buffered so you don't write thousands of tinygrams.

  • Hoe to convert a String to Triple DES Key

    Hi
    can Someone help me how to convert a string to TRipleDES key, some times the string can be less than
    24 bytes ( but DESedeKeySpec needs at least 24 bytes).
    thanks
    chintha

    I would take a slightly different approach than that offered by previous posts. This is from looking at what OpenSSL does for generating keys.
    1) Do a String.getBytes() from your password (or String.getBytes("UTF-8") if you are using other than ASCII).
    2) Generate a SHA-1 hash from the bytes. This gives you a 20 byte value.
    3) Compute a SHA-1 hash of the original hash and the password. This will give you another 20 byte value.
    4) Take the first 20 bytes from hash #1 and the first 4 bytes of hash #2 to get a 24 byte value.
    5) Give the 24 byte value odd parity (this means that each byte has an odd number of 1 bytes). You'll need to write a bit of your own code to do this.
    6) Finally, use this 24 byte, odd parity value to generate your DES key.

  • Unicode: Is it Possible to convert a string, or text, for Output?

    Can you take a string (or text) in Unicode (4 bytes each character),  and by using its string (or text), as input it to a Function Module, or Method, have the string's hex values converted into the old non-unicode value (2 bytes each character) to send to an external system?   
    I wish it were this easy, but am finding out it is not. Seems like whenever I run  a process to convert a field (4 bytes) in the new unicode system, to old non-unicode (2 bytes each), and move it back into a field in the unicode system, it automatically  converts it back to 4 bytes automatically?
    It is causing issues on the external tergat system that is not using unicode.
         Thank-You.

    Not that I know of. But you could convert your text to RAW or XSTRING, and send that value to the external system.

  • Converting unsigned to java signed byte value

    Hey ,
    i need to use a raw address in a client i am writing but, of course, the address contains a byte outside of the java signed byte range. if any one could tell me what an unsigned byte of 224 in signed java is i would be very grateful, if you could also show how you did this it would be appreciated. thank you =)

    Re: Converting unsigned to java signed byte value
    i need to use a raw address in a client i am writing
    but, of course, the address contains a byte outside
    of the java signed byte range.
    if any one could tell
    me what an unsigned byte of 224 is in signed java
    I would be very grateful, if you could also show how
    you did this it would be appreciated. thank you =)You misunderstand signed/unsigned.
    A byte has 8 bits. It can represent 256 different values.
    Viewed as an unsigned scalar the range is [0;255].
    Viewed as a signed two's-complement scalar the range is [-128;127].
    Values [0;127] are obviously the same byte values in the two views.
    What the other half of the possible byte values represent depends on what view you adopt.
    You don't need to convert anything.
    public final class Byte224 {
        static byte[] byteArray = {
            (byte)224, (byte)'\n'
        public static final void main(final String[] arg) {
            System.out.println("0x"+Integer.toHexString(byteArray[0]&0xff));
            System.out.println(Integer.toString(byteArray[0]&0xff));

    Encephalopathic wrote
    Again, why?One of the problems (have been dued) in my codelab asks us to write a class as follow
    Write a class definition of a class named 'Value' with the following:
    a constructor accepting a single integer paramter
    a constructor with no parameters
    a method 'setVal' that accepts a single parameter,
    a boolean method, 'wasModified' that returns true if setVal was ever called for the object.
    a method 'getVal' that returns an integer value as follows: if setVal has ever been called, it getVal returns the last value passed to setVal. Otherwise if the "single int parameter" constructor was used to create the object, getVal returns the value passed to that constructor. Otherwise getVal returns 0.
    The setVal(int y) returns nothing, so how do I know whether it has been called or not?

  • How to convert an Image to a byte array?

    I want to make a screenshot and then convert the image to a byte of arrays so I can send it through a BufferedOutputStream.
    try
                   robot = new Robot();
                   screenshot = robot.createScreenCapture(new Rectangle(500,500));
                   imageFile = new File("image.png");
                   ImageInputStream iis = ImageIO.createImageInputStream(screenshot);
                   byte[] data = new byte[1024];
                   byte[] tmp = new byte[0];
                   byte[] myArrayImage = new byte[0];
                   int len = 0;
                   int total = 0;
                   while((len = iis.read(data)) != -1 ) // LINE 52 --- EXCEPTION CATCHED HERE
                        total += len;
                        tmp = myArrayImage;
                        myArrayImage = new byte[total];
                        System.arraycopy(tmp,0,myArrayImage,0,tmp.length);
                        System.arraycopy(data,0,myArrayImage,tmp.length,len);
                   ios.close();I get this exception while running:
    Exception in thread "Thread-0" java.lang.NullPointerException
    at Server.run(Server.java:52)
    at java.lang.Thread.run(Unknown Source)

    Fixed that. I got a new problem.
    When I connect to my simple server application that reads the image file, converts it to an array of bytes and sends it back, the file is created on the client side and it containts data, but I am not able to open the image. I have checked that the image that the server is sending is working. So where is the problem?
    The client application recieves the image as following:
    public void run()
            try
                socket = new Socket("127.0.0.1", 2000);
                BufferedOutputStream out_file = new BufferedOutputStream(new FileOutputStream("recieved_img.png"));
                BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
                int inputLine;
                while((inputLine = in.read()) != -1)
                    char c = (char)inputLine;
                    System.out.println(c);
                    out_file.write(inputLine);
            catch(IOException err){ err.printStackTrace(); }
        }And the server sends the image like this;
    try
              socket = server.accept();
              in=new BufferedReader(new InputStreamReader(socket.getInputStream()));
              out = new BufferedOutputStream(socket.getOutputStream());
              out.write(25);
              while((inputLine = in.readLine()) != null)
                   System.out.println(myArrayImage.length);
              System.out.println(inputLine);
                        out.write(myArrayImage);     // Send the array of bytes
         }

  • Looking for a simple way to convert a string to title case

    New to LiveCycle and Javascript.  Looking for a simple way to convert a string to title case, except acronyms.  Currently using the the following, it converts acronyms to lower case:
    var str  =  this.rawValue;
    var upCase = str.split(" ");
    for(i=0; i < upCase.length; i++) {
    upCase[i] = upCase[i].substr(0,1).toUpperCase() + upCase[i].substr(1).toLowerCase();

  • Convert a String to Decimal Format in European format

    Hi Experts,
    I am having a string as a context type for a input field, where the user can enter the Price, I need to convert the same into European format "###.###,00", I am using this below code to convert the string to decimal format
    User will enter the input as 10 as it needs to be converted into 10,00. Also, 1000 which has to be converted as 1.000,00
    String Str1 = wdContext.currentvn_temptable.getVa_TempUnitPrice();
    Locale mylocale  = Locale.GERMAN;
    String pattern="###.###,00";

    Please let me know, how to convert a String to Quantity in European format
    Thanks & Regards,
    Palani

    Hello!
    Try to change your pattern to this one 
    Locale mylocale  = Locale.GERMAN;
    String pattern = "#,#00.00";                    
    NumberFormat nf = NumberFormat.getNumberInstance(mylocale);
    DecimalFormat df = (DecimalFormat)nf;
    df.applyPattern(pattern);
    String output = df.format(1111111.222);
    Pattern has an influence on number of digits between separators, but you have to use ',' for grouping and '.' for decimal. Character values for separators correspond to your Locale object.
    Thanks, Mikhail
