How to get the file data in chunks

[dhananjaykumar singh]

Hi,
I am accessing a file using "InputStream" and getting the whole document data. My requirement is to get the document data in chunk(or in small pieces).

Can you please tell me how to perform this operation of getting whole file contents in collection of small pieces.

thanks in advance,
Dhananjay

The read( byteArray ) method will read up to the size of the array. Would that work as a chunk for you? You could put a read like this in a loop until it returns -1 for end of stream.

byte[] chunk = byte[chunkSize];
// in a loop
   i = reader.read( chunk );
   do something with chunk
