Challenge: HashSet to TreeSet

HashSet to TreeSet

Write Java code to convert a HashSet object to a TreeSet object. Remember that HashSet doesn’t contain sorted data, while TreeSet does.

Output the new TreeSet object named result_treeSet. Although the conversion from TreeSet to String is unnecessary, it should be done for output reasons.
