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
