Program: How to iterate through HashSet?

Below example shows how to read all elements from the HashSet objects. You can iterate through HashSet by getting Iterator object. By calling iterator() method, you can get Iterator object.

package com.java2novice.hashset;

import java.util.HashSet;
import java.util.Iterator;

public class MyHashSetRead {

	public static void main(String a[]){
		HashSet<String> hs = new HashSet<String>();
		//add elements to HashSet
		hs.add("first");
		hs.add("second");
		hs.add("third");
		Iterator<String> itr = hs.iterator();
		while(itr.hasNext()){
			System.out.println(itr.next());
		}
	}
}

second
third
first
