Iterate Treeset elements using Iterator iterator()

BACK

This tutorial explains how  to Iterate Treeset elements using  Iterator<E> iterator() method.

To read objects using Iterator.

By calling iterator() method you will get Iterator object,

Through which you can iterate through all the elements of the TreeSet.

Example

import java.util.Iterator;

import java.util.TreeSet;

public class MySetIteration

{

   public static void main(String a[])

{     

       TreeSet<String> ts = new TreeSet<String>();

       ts.add("one");

       ts.add("two");

       ts.add("three");

       Iterator<String> itr = ts.iterator();

       while(itr.hasNext()){

        System.out.println(itr.next());

       }

   }

}

Output

         one

         three

         two
