public final int compare(java.lang.Object o1,
                         java.lang.Object o2)
Description copied from interface: java.util.Comparator
Return an integer that is negative, zero or positive depending on whether the first argument is less than, equal to or greater than the second according to this ordering. This method should obey the following contract:
  • if compare(a, b) < 0 then compare(b, a) > 0
  • if compare(a, b) throws an exception, so does compare(b, a)
  • if compare(a, b) < 0 and compare(b, c) < 0 then compare(a, c) < 0
  • if compare(a, b) == 0 then compare(a, c) and compare(b, c) must have the same sign
To be consistent with equals, the following additional constraint is in place:
  • if a.equals(b) or both a and b are null, then compare(a, b) == 0.

Although it is permissible for a comparator to provide an order inconsistent with equals, that should be documented.
