                         Object obj2)

Specified by:

compare in interface Comparator

Parameters:

obj1 - first byte array to compare.

obj2 - second byte array to compare.

Returns:

negative number if obj1 < obj2, 0 if obj1 == obj2, positive number if obj1 > obj2.

Throws:

ClassCastException - if either argument is not a byte array.
