6. Suppose you have an array of objects, objl). Also, assume a Comparator class implementing Comparator has been created and that its name is CompClass. Write code that will let you sort the obj[] array using the sort method of the Arrays class. Assume that CompClass appropriately compares two obj objects. 7. Realizing that if String stringA comes alphabetically before String stringB, then it can be said that stringA 0) { System.out.println("ABC"); 3 if (s2.compareTo(sl) == 0) { System.out.println("XYZ"); 3 if (sl.compareTo(s2)
