converting array to set

import java.util.Set;

public class ArrayToSet {

       public static void main(String[] args) {

              String[] strArr = { "sunday", "monday", "tuesday", "wednesday",

                           "thursday", "friday", "saturday" };

              // To convert an array into a Set first we convert it to a List.

              //  we create a HashSet and pass the list as the constuctor

             

              List<String> strList = Arrays.asList(strArr);

              System.out.println("list objects are:" + strList);

              Set<String> strSet = new HashSet<String>(strList);

              System.out.println("set objects are:" + strSet);

              System.out.println("iterating the set");

              Iterator<String> itr = strSet.iterator();
