The java.util.SortedSet.iterator() method is used to return an iterator of the same elements as the set. The elements are returned in random order from what present in the set.
Syntax:
Iterator iterate_value = sortedSetInstance.iterator();
Parameters: The function does not take any parameter.
Return Value: The method iterates over the elements of the set and returns the values(iterators).
Note: The iterator() method in SortedSet is inherited from the Set interface in Java.
Below program illustrate the java.util.Set.iterator() method:
// Java code to illustrate iterator()  import java.util.*;  public class SortedSetDemo {    public static void main(String args[])    {          // Creating an empty Set        SortedSet<String> set            = new TreeSet<String>();          // Use add() method to        // add elements into the Set        set.add("Welcome");        set.add("To");        set.add("Geeks");        set.add("4");        set.add("Geeks");          // Displaying the Set        System.out.println("SortedSet: "                           + set);          // Creating an iterator        Iterator value = set.iterator();          // Displaying the values after        // iterating through the iterator        System.out.println("The iterator values are: ");        while (value.hasNext()) {            System.out.println(value.next());        }    }} |
Output:
SortedSet: [4, Geeks, To, Welcome] The iterator values are: 4 Geeks To Welcome
