How to copy bytes to an array byte variable....??

Question

Hi everyone....can anyone help me out...i want to store byte into an array-byte variable,(byte by byte), which are returning from the readByte() function of DataInputStream.
Thank you

Answer 1

int filesize = request.getContentLength();
byte dataBytes[] = new byte[filesize];
int read=0;
while( read <filesize)
bytesRead[read++] =  in.readByte();  // *in* is object of DataInputStream
}Change all that to this:
int count;
byte[] buffer = newbyte[8192];
ByteArrayOutputStream baos = new ByteArrayOutputStream();
while ((count = in.read(buffer)) > 0)
  baos.write(buffer, 0, count);
byte[] data = baos.toByteArray();Of course, like your code, this assumes that the data will fit into memory. It is preferable to process the data read each time as you go rather than accumulating it all first and then processing. This saves both time and space.
