How to get (remove) a specific element in a HashSet by index?

Question

Java

import java.util.*;
import java.io.*;


class Ideone
{
  public static void main (String[] args) throws java.lang.Exception
  {
  HashSet<Integer> set = new HashSet<>();
    set.add(1);
    set.add(2);
    set.add(3);

No way, HashSet is an unordered collection.
