How To Create Iterator object from the HashSet object and iterate them to get displayed?
It seems to me that i cant use listIterator() Method with HashSet Object. I have no idea why.

This is My code:

import java.util.HashSet;
import java.util.ListIterator;

public class MyHashSet
{
	public MyHashSet()
	{
	}

	public static void main(String Laythe[])
	{
		HashSet HashSetX = new HashSet(5);

		HashSetX.add(new Integer(1));
		HashSetX.add(new Integer(2));
		HashSetX.add(new Integer(3));

		System.out.println(HashSetX);

		ListIterator HashSetY = HashSetX.listIterator();

		while (HashSetY.hasNext())
		{
			System.out.println("From ListEterator, HashSetY.next() = "
					+HashSetY.next());
		}
	}
}

Java api should be the first place you look for any of this stuff. http://java.sun.com/...#iterator%28%29

Does this work for you? You gotta import java.util.Iterator though.

Iterator HashSetY = HashSetX.iterator();

		while (HashSetY.hasNext())
		{
			System.out.println("From ListEterator, HashSetY.next() = "
					+HashSetY.next());
		}
