public void reverse( byte[] b ) {
  for( int i = 0; i < b.length / 2; i++ ) {
    swap( b, i, b.length - i - 1 );
  }
}

private void swap( byte[] array, int a, int b ) {
  int temp = array[a];
  array[a] = array[b];
  array[b] = temp;
}

If "bytes" is an array of bytes

for (int i=0; i<bytes.length; i++)
{
    bytes[i] = bytes[i] == 0 ? 1 : 0;
}
