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:
Java
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
