Browse a TreeSet with Iterator in Java

The iterator() is used to get an iterator object through the elements in the TreeSet list in ascending order.

In this example, we create a TreeSet and initialize it with elements, then we browse with iterator():

import java.util.Iterator; 
import java.util.TreeSet; 

public class TreePath {
 public static void main(String[] args) {
 // creating TreeSet
 TreeSet  tset = new TreeSet(); 
 
 // add elements to treeset
 tset.add(11); 
 tset.add(5); 
 tset.add(6); 
 tset.add(2); 
 tset.add(1); 
 
 // create an iterator object in ascending order
 Iterator iterator = tset.iterator(); 
 
 // displaying data from TreeSet
 System.out.println("The elements from treeset "+
" in ascending order: "); 
 while (iterator.hasNext()){
 System.out.println(iterator.next()); 
 }
 } 
}

Runtime:

Treeset elements in ascending order: 
1
2
5
6
11
