Chapter 21.2, Problem 21.2.2CP
Program Plan Intro
Set:
Set is a data structure that is used for storing and processing non duplicate elements. It is an interface which extends collection and it is an unordered collection of objects.
Set is implemented by LinkedSet, HashSet or a TreeSet.
It is given that objects o1 and o2 are equal.

What must be true about valid equals() and hashCode() methods?
O 01.equals(02) = o1.hashCodel) == 02.hashCode()
O 01.hashCode() == 02.hashCode = 01.equals(02)
O !01.equals(o2) = 01.hashCode() != 02.hashCode()
O 01.hashCode() != 02.hashCode() = !o1.equals(o2)
O hashCode must have a low collision rate for the hash table to work correctly

Select all that apply. Hint: you should be able to answer this question based only on the material presented in class. If E inherits Object.hashCode(), then there will be no collisions. A HashSet iterator should iterate through the Hashset elements in the order in which they were added to the Hashset.
