Explanation
public byte[] toByteArray()
Returns a new byte array containing all the bits in this bit set.
More precisely, if
byte[] bytes = s.toByteArray();
then bytes.length == (s.length()+7)/8 and
s.get(n) == ((bytes[n/8] & (1<<(n%8))) != 0)
for all n < 8 * bytes.length.
Returns:
a byte array containing a little-endian representation of all the bits in this bit set
