Conversion of String to Bytes and Length Calculation

hi,
How can I convert
String to Bytes
Bytes to String
int to Bytes
Bytes to int
& int to String
And I have to calculate the Length in Bytes of a String and int.
Thanks

double d = Double.parseDouble(new String(byteDouble)); Java doesn't seem to accept to convert byteDouble to a String...

Conversion of String to byte[ ]

Hi everybody
I have a Byte[] value in one of our client database it seems like this -- 00033DB7FB87EC4EB371BCC9D3BF13EC
when they import into CSV it became String
I need to Dump into my database what ever you see in that Byte[].the value is already a conversion only so i need to dump as it is.
now the real problem is how to convert the same String as Bytes
if i use String.getBytes() it exceeding the Field Length
my filed length in the database is Binary (16)
Plz do the needful
Thanks for ur Help in advance

So System.out.println(theString) results in "00033DB7FB87EC4EB371BCC9D3BF13EC"?
Then .getBytes() is not what you need. It will get the bytes representing this unicode string in a specific encoding (such as ISO-8859-1, UTF-8 or the like).
You need to parse to digits each as hexadecimal numbers (using Integer.parseInt() for example, don't forget to specify the radix 16) and convert that to a byte[] array (the length of the byte array should be half the size of the String).
Warning: because Java knows only signed ints, you'll have to jump through some hoops to get the correct value. Assuming String a contains 2 hexadecimal digits, you get the byte value like this:
byte b = (byte) (Integer.parseInt(a,16) & 0xFF);

Serialized byte[] and length

hi,
i have problem to store into oracle database serialized data as byte[] trought CMP's .. the problem is that all data bigger than 1000 bytes there is following sql exception thrown :
java.sql.SQLException: ORA-01483: invalid length for DATE or NUMBER bind variable
and rollback is done immediately
please help!

Hi,
What is your table definition for that bean? What is the type of the corresponding field in your bean? The error message is about DATE or NUMBER columns. Can you check your mapping again? If your mapping is ok, please turn the logging level to FINEST and send us the segment of your server.log containing the exception.
Thanks,

How to get the string's byte length?

I have some string,I want to get the string's byte length,how
can do it?
for example:
<cfoutput>#len('hihi，这是测试')#</cfoutput>
output is 9
I want to get the byte length is 14, how can i get it?
Thanks.

Oh, sorry, whatever the term is (I'm crap with jargon). The
value returned
by asc() for those chars was only two bytes (ie: four hex
digits). I
didn't realise there was more to it than that, and that
2-byte value maps
to some other THREE byte value. I need to do some reading...
> that's what both cf & java counted as the length.
CHARACTER length, sure. No-one's disputing that. On the other
hand,
no-one's asking about it, either.

[groan]
Yes, that's a reasonable strawman there. I was only putting
it in a file
so I could save it and check the number of bytes occupied by
the data.
Clearly... CLEARLY... the OP is not asking for a character
length of that
string. They've said as much.
I copy and pasted the string from their post, and used it as
a
demonstration of how "nine" is not the right answer for the
BYTE LENGTH of
that string. Whether or not the original string was UTF-8,
UTF-16 or
special-marmoset-encoding, it almost certainly was NOT in a
fictitious kind
encoding in which each of those particular characters only
occupied one
byte each, which would mean that "nine" is the correct answer
to the
question.
When I copied those characters from either the web browser
for from my
text-based news agent, notepad identified them (and rendered
them
correctly) as UTF-8, so I'm fairly confident they ARE UTF-8.
Of course
this could be down to some intermediary encoding (pasting
them in to the
original posting, for example, via some encoding-transforming
mechanism),
but Occam's Razor suggests the original question was from a
UTF-8 POV.
But maybe we should quit speculating and ask the OP. Unless
they've
buggered off in despair of how drawn out all this is getting.
For which I
would not blame them.

Hi,
The above error appears due to date format is differnt from SAP query generator and SQL server.
So you need convert all date in above query to SQL server required format.
Try to convert..let me know if not possible.

You can search the forums for that error message and find previous discussions - they all boil down to the same problem. Somewhere in your query that calls this function, the code invoked implicitly converts from string to date/datetime. In general,
this works in any version of sql server if the runtime settings are correct for the format of the string data. The fact that it works in one server and not in another server suggests that the query executes with different settings - and I'll assume for
the moment that the format of the data involved in this conversion is consistent within the database/resultset and consistent between the 2 servers.
I suggest you read Tibor's guide to the datetime datatype (via the link to his site below) first - then go find the actual code that performs this conversion. It may not be in the function you posted, since that function also executes other functions.
You also did not post the query that calls this function, so this function may not, in fact, be the source of the problem at all.

Byte[ ] and String

I am reading data into a byte array which i declare to be of size (lets say 40). the data that i read varies between lets say 30-40(but i still delare the byte array to be of size 40 so that it has enough space to handle cases from 30-40). The problem is that I need to create a string with this data...and i do so using
String data = new String (byteArray[); //where byteArray holds data that i read
but for some reason when i try to print data...it prints the character [][][][]][][] for the unused portion of the byte array.
for example if my data is 123456789......................30.
and i read it into a byte array of size 40
and then convert to string and try to print it wil print 123456789................30[][][][][][][][][] .
how can i solve this problem?

heres some code of what im trying to do, if you dont understand datagrams you can just ignore those specifis
public String recieveCommand(){
byte[] data = new byte[40];
try{
packet=new DatagramPacket(data,40);
socket.receive(packet);
}catch(Exception e){System.out.println(e.toString());}
String command=new String( packet.getData() );

Got String= "100 600" and want to get out (length of first number not const

Ive got String= "100 600" and want to get out
the value 600 into int.
Length of first number is not const : it can be 100 or 3000
How can how do it ?
10x for the help

It would depend on the format of your string. If you can gurantee that the format will always be "number number" then you can use the StringTokenizer to split the two numbers and take the second one. The code would look similar to this:
String s = "100 600";
StringTokenizer st = new StringTokenizer(s, " ");
//--- This "scrolls" past the first number.
st.nextToken();
String num = st.nextToken();
The variable num will always have the second number.
Hope this helps.

Conversion from hex string to bytes withh out ascii

how to convert hex string to byte numbers without ascii codes,then all the converted bytes should come into a packets

rajkumar5 wrote:

What people consider ASCII and Hex with strings varies so much, you pretty much need to supply an example. The best way is to create a VI with default data in the string control and indicator (to show what you want out).

How to read binary files wrt specific BYTE size and length??

Hello Everyone,
I have a project I want to accomplish. I have a binary file, and I would like to read the data and print on wfm in a specific order and size.
The data is 16 bit binary type , and needs to be read in chunks of 2 bytes.
i have 30 bytes of sample 1.
followed by 2 bytes of sample 2.
followed by another 2 bytes of sample 3.
steps 2-4 should be repeated 10 times and then i should read sample 4 which is of 2 bytes.....
How should I do it?? I don't have any VI build... all i have is the example VI...
can anyone pleasehelp me???
Now on LabVIEW 10.0 on Win7

smercurio_fc, sorry for the confusion, i will try my best to explain...
1. No, i don;t have to read the file again, once it has read, I used
while loop just to see the data updating (i press run, and before i can
visualize i have the waveforms; i can get rid of the while loop)
2. I have 30 different values of 1 sample. actually, the data is cmg
from tri-axial accelerometer; each axis is of 10 bytes(hence 3*10 =
30bytes)
3. I am repeating the steps 2-4 10 times because the data was written
into the binary file after 10 times sampling the sensors(if first 3
samples are read @ 1000hz, sample 4 was read at 1000/10 = 100hz)
4. I am using the graphs to interpret the values, that's it. The
values are already scaled when they were wrote to the binary file, I
have to simply interpret it.
I have made some changes in the VI, now i am reading only the first
30bytes, that too, in chunks of 10-10-10 bytes, and plotting the 3
samples simultaneously on a waveform chart. (will approach 1
sensor/sample at a time) and running the loop for 10 times. I have changed I8 to I16 now.
Please let me know if it makes sense to you now.
P.S. each sample is a sensor data.

Inserting strings of printable and non printable characters

I would very much appreciate some help with the following
To handle an interface with a legacy system I need to create strings containing both printable and non-printabel ascii characters. And with non printable characters I mean in particular those in the range of ASCII 128 to 159.
It seems it is not possible to insert a string containting both printable and not printable characters from the afore mentioned range into a VARCHAR2 table column as the following demonstrates:
insert into test values(chr(156)); -- this inserts the 'œ' symbol.
SQL> select test, ascii(test), length(test), substr(test,1,1), ascii(substr(test,1,1))from test;
TEST       ASCII(TEST) LENGTH(TEST) SUBSTR(TEST,1,1) ASCII(SUBSTR(TEST,1,1))
┐                  156            1That the the character mapped is shown as '┐' and not 'œ' is not really issue for my application, what is important is that the ASCII value is shown as 156, which is the ASCII code of the character I inserted.
What is however strange (actually probably not strange but has to do with the lack of understanding of the issue at hand) is that substr returns an empty string...
Now I try to insert a concatenated string, first the "non printable" character then a printable character
insert into test values(chr(156)||chr(65));
SQL> select test, ascii(test), length(test), substr(test,1,1), ascii(substr(test,1,1))from test;
TEST       ASCII(TEST) LENGTH(TEST) SUBSTR(TEST,1,1) ASCII(SUBSTR(TEST,1,1))
A                   65            1 A                                     65For some reason the not printable character (chr(156)) is now not inserted or at least does not appear when I selected the data from the table, this effect seems to apply to all characters in the range of ASCII 128 to 159 (tried some but not all) However for instance CHR(13) can be inserted as part of a string as shown above .
For our application I really don't care much what character is shown or not show, what is important is that I can retrieve the ASCII value and that this value matches the one I inserted which for some reason does not seem to work.
This seems to be, at least to some extent a character set issue. I have also tested this on a database with character sets set as follows
NLS_CHARACTERSET
WE8MSWIN1252
NLS_NCHAR_CHARACTERSET
AL16UTF16
With WE8MSWIN1252 the described issue does NOT occur, however unfortunately I must use NLS_CHARACTERSET AL32UTF8 which produces the results as described above!
As said any insights would be much appreciated as I am slowly but surely starting to despair.
For completions sake, character sets are set as follows (changing it is NOT an option):
NLS_CHARACTERSET
AL32UTF8
NLS_NCHAR_CHARACTERSET
AL16UTF16
The test table is created as follows
CREATE TABLE TEST
TEST VARCHAR2(1000 BYTE)
Database Version 11.2.0.3.0
Edited by: helios.taraba on Dec 2, 2012 10:18 AM --Added database version
Edited by: helios.taraba on Dec 2, 2012 10:24 AM Added description of test results using NLS_CHARACTERSET WE8MSWIN1252

Hello Orafad,
Thanks for your reply, at least I understand the effects I'm seeing i.e.
+"For multibyte character sets, n must resolve to one entire code point. Invalid code points are not validated, and the result of specifying invalid code points is indeterminate."+
http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions026.htm
You are absolutely right I could use chr(50579) to get the ligature symbol. However as what we are trying to achieve is to implement a legacy interface to a 20+ years old subsystem we are actually not so much interested in the symbol itself but rather in the ascii value of that symbol (156 as you so rightly point out in the win-1252 characterset), this particular field represents the lenght of the message being sent to the subsystem and can vary from decimal 68 to 164 and is also considered in a checksum calculation which is part of the message.
As changing the nls_characterset of the database is not an option I guess I only have one reasonable avenue to resolve this namely to push the functionality to added the "encoded" length of the message (and the calculation of the checksum) to the java driver which is responsible for sending the message (tcp/ip) to the subsystem. Here we should not have any issues adding a byte with the value 156 (or any other for that matter) to the datastream.
Thankfully all other fields have characters with ascii values below 128 and above 31.
I'm going to leave my question as un-answered for a bit longer in the hopes of someone coming up with a golden bullet, although not getting my hopes up.
Thanks, Helios

Converting from spreadshet string to array and then back to spreadsheet string

My questions is; why is the Spreadsheet string to array function creating more data than the original string had when you change the array back into a spreadsheet string. Im trying to analyze a comma delimited file using array functions since my column and row size is constant, but my data varies. Thus my reason for not using string parsing functions which would get more involved and difficult. So, however, after i convert to a 2D array of data from the comma delimited file I read from, and then I convert back to string using the Array to Spreadsheet String, I get added columns to the file, which prevents another program from receiving these files. Also, the data which I am reading is not all contiguous, it has gaps in some places for empty data. Looking at the file compared to the original after it has gone from string to array and then back to string again, looks almost identical except for the file size which got larger by 400 bytes and where the original file has empty spaces, the new file has a lot of commas added. Any idea?
Charles

The result you get is normal when the spreadsheet string contains rows of uneven length. Since the array rows have the same number of elements, nil values are added during the coonversion. And of course, the back to string conversion keep those added values in the string, with the associated commas.
example : 3 x 3 array
1,2,3
4
5,6,7
is converted into
1 2 3
4 0 0
5 6 7
then back to
1,2,3
4,0,0
5,6,7

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.
