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()); } } } |
SortedSet: [4, Geeks, To, Welcome] The iterator values are: 4 Geeks To Welcome
