WebThe most important difference between the HashSet, TreeSet, and LinkedHashSet class lies in the order in which its iterator returns contents of the set. HashSet makes no guarantees on the iteration order of the set or even the order will remain constant over time. TreeSet, depending on the constructor used, is iterated according to the natural ... WebNull Keys/ Values. HashMap allows a single null key and multiple null values. TreeMap does not allow null keys but can have multiple null values. Homogeneous/ Heterogeneous. HashMap allows heterogeneous elements because it does not perform sorting on keys. TreeMap allows homogeneous values as a key because of sorting.
