How to know the length of a Byte array?

how to know the length a byte array if it is an argument of the method, e.g.
public byte[] hash(byte[] data) throws Exception
I wanna store the length of data into a integer in the method of hash, but no idea how to get it
THanks!

to conclude:
I am a newbie, I wanna know , those "System"
methods as well.What exactly does that have to do with your original question?
or instance:
System.arrowcopy() , where can I find the
definition also?You probably meant System.arraycopy. The documentation is called JavaDoc and for Java 1.5 (a.k.a. 5.0) it can be found here: http://java.sun.com/j2se/1.5.0/docs/api/index.html
If you've not yet found the API documentation, then I'm pretty sure you should start with some tutorials, they probably point to all the interesting documentation as well.

How to know the length of internal table...

Hello experts,
How can I know the line size of my internal table since it will be dynamic
and I am just writing my report manually(not ALV) so I will be using sy-uline,
sy-vline, sy-linsz, etc.
So I can declare my sy-ulines according to the total length of my output.
Also, is this possible in ALV:
Header 1               *
      Header 2             *
         -OUTPUT-
Thanks again!

Hi
You can use the DESCRIBE statement to get the number of lines in an internal table:
DATA: num_lines TYPE i.
DESCRIBE TABLE itab LINES num_lines.
num_lines will now hold the number of lines in your table.
I don't believe you can have multiple header rows in ALV you will probably need to group your records or summarise them to achieve a similar result.
Hope this helps
Andy

Sorry, I misunderstood your requirement, using the DESCRIBE TABLE statement will fill the system field sy-tleng with the line size so immediately after doing DESCRIBE... just pass sy-tleng to an integer type variable.
Kind regards
Andy

How to get the encoding of a byte array (or ByteBuffer)?

Hello;
I have a byte array which may be encoded with any kind of encoding and I want to determine which encoding was used to encode this byte array. Does anyone know how to do this?
Thanks in advance..

Byte Arrays have NO encoding at all. When bytes are packed to characters, that is where encoding comes into picture. java.lang.String has enough methods to do that.

How to get the file size (in bytes) for all files in a directory?

How to get the file size (in bytes) for all files in a directory?
The following code does not work. isFile() does NOT recognize files as files but only as directories. Why?
Furthermore the size is not retrieved correctly.
How do I have to code it otherwise? Is there a way of not converting f-to-string-to-File again but iterate over all file objects instead?
Thank you
Peter
java.io.File f = new java.io.File("D:/todo/");
files = f.list();
for (int i = 0; i < files.length; i++) {
System.out.println("fn=" + files);
if (new File(files[i]).isFile())
     System.out.println("file[" + i + "]=" + files[i] + " size=" + (new File(files[i])).length() ); }

Also, in future, when posting code, code snippets, HTML/XML or input/output, please use the code tags to retain the indentation and formatting.   To do that, select the code and click the CODE button seen on the Plain Text tab of the message posting form. It took me longer to clean up that code and turn it into an SSCCE, than it took to +solve the problem.+

Is there a solution on how to increase the length so that error is avoided.
There is no such error occuring while crating condition table in V/03

Hi,
You can try to use the type string:
form like zscr_data_hdr-form,
werks like zscr_data_hdr-werks,
matnr like zscr_data_hdr-matnr,
verid like zscr_data_hdr-verid,
lot like zscr_data_hdr-lot,
lot_qty like zscr_data_hdr-lot_qty,
udate like zscr_data_hdr-udate,
utime like zscr_data_hdr-utime,
zuser like zscr_data_hdr-zuser,
processed like zscr_data_hdr-processed,
defect like zscr_defect_data-defect,
vornr like zscr_route_data-vornr,
fieldxx type string,
dayst like zscr_data_hdr-dayst,
end of t_data.
So you can save you informations of every fld<n> concatenating their values into fieldxx.

another
32K bytes of non-volatile configuration memory.
what is the actual memory size? is it 64 or 32?
Can i install an IOS which minimum requires 64Mb memory in this Router?

How to know the memory ?
cisco 2621 (MPC860) processor (revision 0x600) with 53248K/12288K bytes of memory.
when you get the above output from sh ver,
simply add 53248k + 12288k and always devide by 1024.
e.i
53248k + 12288k / 1024 = 64
64MB is your total memory in your router

Hi Patricia,
is it working for restricted key figure and calculated key figure ??
Note Number Fisc Period Opening Days
1 1 2
2 1 3
3 1 0
because I have other restriction, so I create two restricted key figure..
RK1 with restriction : Total Number of Note,
RK2 with restriction : Total Opening Days ,
then I Created a calculated key figure, average opening days in a period
CK1 = RK2 / RK1..
in this case, I am not sure if it will work or not..
for example, during RK2 calclation, it might be this   2+3 = 5, the line with 0 will be ignored..
during RK1 calcualtion, it might be 1 + 1 + 1 = 3. ---> Not sure in this case, the line with opening days 0 will be calculated or not..
could you please confirm..

With a contract number, how to know the total PO release value against it?

Usually one contract corresponds to multiple PO records, now we know the contract number, then how to know the total PO release value against this contract. In other word, we would like to know the total release value of all the POs with the same contract number. To just input the contract number in EKPO table? but then look for which field in this table to add these PO release values up?
We will give you reward points!
Thanks!

hi Mohammad,
By following your instruction, input the contract number 4800000112 into Document number field, then hit Enter, get the following (only copy two records here for example), but kind of a mess. Could you let us know which one is the PO release value for this contract?
