Iterate through elements of Java HashSet


   



import java.util.HashSet;

import java.util.Iterator;



public class Main {



  public static void main(String[] args) {



    HashSet<Integer> hSet = new HashSet<Integer>();



    hSet.add(new Integer("1"));

    hSet.add(new Integer("2"));

    hSet.add(new Integer("3"));



    Iterator itr = hSet.iterator();



    while (itr.hasNext())

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