HashSet The HashSet class in the JCF implements the Set ADT. A set is an unordered collection of unique items. Imprtant methods include add, contains, remove, isEmpty and size. https://docs.oracle.com/javase/8/docs/api/java/util/HashSet.html import jave.util.HashSet; HashSet<String> set = new HashSet<String>(); Run the SetORList program. Rerun the program several times with different values of size (see the main method). Try 1000, 10000, 20000, 50000, etc. What can we say about using an ArrayList and using a HashSet? Modify the SetORList to generate a collection of 10 items (Integers for example). Sort the ArrayList (using Collections.sort). How do you sort the data in the set?
