how to set the value of BUFFER SIZE

how to set the value of BUFFER_SIZE ?

Code:

int bytesRead = 0;
byte [] buffer= new byte[BUFFER_SIZE]
bytesRead = inStream.read(buffer, 0, BUFFER_SIZE);
while(bytesRead !=-1){
    outStream.write(buffer, 0, bytesRead);
    bytesRead = inStream.read(buffer, 0, BUFFER_SIZE);
}

thanks

It depends on the memory constraints on your system and if the low-level I/O like TCP/IP uses buffer you might have to be tandem with that. On average local system I/O 4k to 8k would be the 'common sense' size.
