That code contains at least one bug.
This loop isn't correct:
> while (bis.read(temp) > 0) {
> out.write(temp);
> }
bis.read returns the number of bytes that was read, that number can be
larger than 0 but still less than temp.length. You should do something
like this instead:
int len = 0;
while (( len = bis.read(temp)) > 0) {
out.write(temp, 0, len);
}
Your file wile otherwise be corrupt.
