Given:
enum Example { ONE, TWO, THREE }
Which statement is true?
A.
The expressions (ONE == ONE) and ONE.equals(ONE) are both guaranteed to be true.
B.
The expression (ONE < TWO) is guaranteed to be true and ONE.compareTo(TWO) is guaranteed to be less than one.
C.
The Example values cannot be used in a raw java.util.HashMap; instead, the programmer must use a java.util.EnumMap.
D.
The Example values can be used in a java.util.SortedSet, but the set will NOT be sorted because enumerated types do NOT implement java.lang.Comparable.
