sorry,I reviewed this question,and it missed something,my bad,what I mean is
class ByteArrayComparable and it's subclass LongComparator,BinaryComparator
...etc,ByteArrayComparable is not named well beacuse it's subclass is
Comparator, a comparator is a tool,it's not right that a comparator extends a
comparable.
