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());
  }
}
