How to Read a File into a Byte Array??
I want to make an array of data objects that works as a byffer to write from a file to another file
do you have any sygestions?
The way I would do it (if I dont misunderstand your question) is to use FileInputStream to pass in the streaming data source.
then read the file source to a list object. For example, LikedList.
then tell the LikedList to transcribe itself to an array of any type, in this case, byte.

How to read .txt file into a 2D array ? Pls help !
I have a .txt file with contents as shown :
1 0 1 0 1 0 1 0
1 0 1 1 1 0 0 1
1 0 1 0 1 0 1 0
1 0 1 1 1 0 0 1
1 0 1 1 1 0 0 1
1 0 1 1 1 0 0 1
1 0 1 1 1 0 0 1
1 0 1 1 1 0 0 1
1 0 1 1 1 0 0 1
1 0 1 1 1 0 0 1
and so on...until 10 samples in total.
How do I create a class which has a method (which I can call later) to put all those binary digits in a 2-D array ? The method should automatically extract data from the .txt file and put it into a 2-D array. How do I do that please ?
Please help someone ? It's pretty urgent....:-(This one takes the cake: essentially the same question, cross-posted 11 times:

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 Win7smercurio_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.
Now on LabVIEW 10.0 on Win7

How to read binary file into a 2D float array??
Hi All,
I really need help to get this one as I am stuck and can't seem to find any way out of it. I am given a '.dat' file that has float values in it. I want to read this file in java and put it in a 2D float array. The file has basically a matrix of float values. What I want to do is to read this binary file and put all its data into 2D float array (float [] []) so that I can use it in my program. Is there a way to read file like this? I did find a similar matlab code (below) but cant seem to find anything in java and i really want to do this in java only.. I will appreciate ur help in this one.
thanks very much
Nitya
fid = fopen('datafile.dat');
A = fread(fid,[50 50],'float32');
fclose(fid);I shud have shown the two ways that i Already tried. here they are..
first one using DataInputStream and then trying to readFloat()
DataInputStream dis = ....
Float f = dis.readFloat();This code gives code gives me some random values like this.. (i had a loop)
5.8758974E-14
-0.41055492
1.5724557E-30
1.06822824E14
-1.91934371E15
3.43829601E13
Other way i tried was this.. which seems right but here i have to convert byte to float and i thnk that code is giving some different results (slightly different float values) not sure why....may be my indexing of the array is wrong to make it a matrix.. or something else...
is.read(bytes, offset....);
int cnt = 0;
int j = 0;
for (int start = 0; start < offset; start = start + 4) {
if(j<50){
myarray[cnt][j] = this.arr2float(bytes, start);
System.out.println(cnt + "-" + j + " = " + myarray[cnt][j]);
j++;
}else{
if(cnt < 50){
cnt++;
j = 0;
}else{
break;
public float arr2float (byte[] arr, int start) {
int i = 0;
int len = 4;
int cnt = 0;
byte[] tmp = new byte[len];
for (i = start; i < (start + len); i++) {
tmp[cnt] = arr;
cnt++;
int accum = 0;
i = 0;
for ( int shiftBy = 0; shiftBy < 32; shiftBy += 8 ) {
accum |= ( (long)( tmp[i] & 0xff ) ) << shiftBy;
i++;
return Float.intBitsToFloat(accum);
Not sure if i am missing some other way to do this... -
How to convert Wav file in to byte array an vise vers into RMS???????????
hi Constantinos Loizou
i m having same problem which u were facing in last month.
my problem i have to save .WAV file into RMS and then retreive it from RMS.
my Code is
Read From RMS
RecordStore rsUser = RecordStore.openRecordStore(file,true);
if(rsUser.getNumRecords() > 0)
try {
byte[] byusrinfo = rsUser.getRecord(1);
InputStream in = new ByteArrayInputStream(byusrinfo,0,byusrinfo.length);
p = Manager.createPlayer(in,"audio/x-wav");
p.start();
return true;
catch(Exception ex) {
ex.printStackTrace();
return false;
rsUser.closeRecordStore();
catch(Exception ex) {
ex.printStackTrace();
return false;
Write in RMS
try {
RecordStore rsUser = RecordStore.openRecordStore(file,true);
int idata = is.available();
byte[] exdata = new byte[idata];
is.read(exdata);
if(rsUser.getNumRecords() > 0) {
rsUser.setRecord(1,exdata,0,exdata.length);
else {
rsUser.addRecord(exdata,0,exdata.length);
rsUser.closeRecordStore();
catch(Exception ex) {
ex.printStackTrace ();
now i have the file successfully when i retrieve it from RMS and p.reliaze() give me exception
javax.microedition.media.MediaException: Failed to realize Player: Malformed wave media: expected 'RIFF'
have u able to solve it. if yes then pls give me solution. or give other solution if this soution is not good
regardz
Hassan MushtaqWell, I'm not going to give you your code on a silver platter. You'll need to put some effort in it yourself.
So look at that available() method yourself an see if you can improve on that. Look at the api docs, there is loads of information there, and often it will give you pointers on why things are not working. -
How can I load a pdf-file into a byte[]?
Hello,
I would like to load a PDF-File into a byte-Array. How can I do this? The standard Streams shouldn't work because this can't be converted into characters. Can it? So, what does work?
Any idea?
Bye,
WolfangWhy would someone not do:
ByteArrayOutputStream baos = new ByteArrayOutputStream();
InputStream is = new FileInputStream("foo.pdf");
byte[] buf = new byte[4096];
for(int len=-1;(len=is.read(buf))!=-1;)
baos.write(buf,0,len);
is.close();
baos.flush();
baos.close();
buf = baos.toByteArray(); // Here are you bytes!You don't need to know the exact size, let ByteArrayOutputStream do it for you. Streams are generally for bytes, Readers/Writers generally for characters. Why exactly did you say: ``The standard Streams shouldn't work because this can't be converted into characters?'' -
How can i load file into database from client-side to server-side
i want to upload file from client-side to server-side, i use the following code to load blob into database.
if the file is in the server-side, it can work, but if it in the client-side, it said that the system cannot find the file. i think it only will search the file is in the server-side or not, it will not search the client-side.
how can i solve it without upload the file to the server first, then load it into database??
try
ResultSet rset = null;
PreparedStatement pstmt =
conn.prepareStatement ("insert into docs values (? , EMPTY_BLOB())");
pstmt.setInt (1, docId);
pstmt.execute ();
// Open the destination blob:
pstmt.setInt (1, docId);
rset = pstmt.executeQuery (
"SELECT content FROM docs WHERE id = ? FOR UPDATE");
BLOB dest_lob = null;
if (rset.next()) {
dest_lob = ((OracleResultSet)rset).getBLOB (1);
// Declare a file handler for the input file
File binaryFile = new File (fileName);
FileInputStream istream = new FileInputStream (binaryFile);
// Create an OutputStram object to write the BLOB as a stream
OutputStream ostream = dest_lob.getBinaryOutputStream();
// Create a tempory buffer
byte[] buffer = new byte[1024];
int length = 0;
// Use the read() method to read the file to the byte
// array buffer, then use the write() method to write it to
// the BLOB.
while ((length = istream.read(buffer)) != -1)
ostream.write(buffer, 0, length);
pstmt.close();
// Close all streams and file handles:
istream.close();
ostream.flush();
ostream.close();
//dest_lob.close();
// Commit the transaction:
conn.commit();
conn.close();
} catch (SQLException e) {Hi,
Without some more details of the configuration, its difficult to know
what's happening here. For example, what do you mean by client side
and server side, and where are you running the upload Java application?
If you always run the application on the database server system, but can't
open the file on a different machine, then it sounds like a file protection
problem that isn't really connected with the database at all. That is to
say, if the new FileInputStream (binaryFile) statement fails, then its not
really a database problem, but a file protection issue. On the other hand,
I can't explain what's happening if you run the program on the same machine
as the document file (client machine), but you can't write the data to the
server, assuming the JDBC connection string is set correctly to connect to
the appropriate database server.
If you can provide some more information, we'll try to help.

How to read an inputStream in UTF-8 into a byte array.
Hi, Java version is 1.4.2. If inputStream.read() is used to read the bytes into a byte array, is it guarenteed that UTF-8 chars are correctly transferred into byte array? Or should we use InputStreamReader? An example would be a great help.
Thanks in advance.I would like to send a byte array read from InputStream to another app where they are converted to UTF-8. In brief
-Read input stream which comes in UTF-8 into a byte array
-Send byte array to another app which will convert it into UTF-8 characters -
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);

System.out.println("file[" + i + "]=" + files[i] + " size=" + (new File(files[i])).length() ); }pstein wrote:

Here is an SSCCE.

public static void main(String[] args) {
java.io.File f = new java.io.File("/media/disk");
// provides only the file names, not the path/name!
//String[] files = f.list();
File[] files = f.listFiles();

}Edit 1:
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.+

How to upload a file into server using j2ee jsp and servlet with bean?
How to upload a file into server using j2ee jsp and servlet with bean? Please give me the reference or url about how to do that. If related to struts is more suitable.
Anyone help me please!u don't need j2ee and struts to do file uploading. An example is as such
in JSP. u use the <input> file tag like
<input type="file"....>You need a bean to capture the file contents like
class FileUploadObj {
private FormFile srcFile;
private byte[] fileContent;
// all the getter and setter methods
}Then in the servlet, you process the file for uploading
* The following loads the uploaded binary data into a byte Array.
FileUploadObj form = new FileUploadObj();
byte[] byteArr = null;
if (form.signFile != null) {
int filesize = form.srcFile.getFileSize();
byteArr = new byte[filesize];
ByteArrayInputStream bytein = new ByteArrayInputStream (form.srcFile.getFileData());
bytein.read(byteArr);
bytein.close();
form.setFileContent(byteArr);
// Write file content using Writer class into the destination file in the server.
