LinkedHashSet Iterator example

This is an example of how to obtain a LinkedHashSet Iterator. The LinkedHashSet API provides us with methods for such operations. Obtaining a LinkedHashSet Iterator implies that you should:

  • Create a new LinkedHashSet.
  • Populate the set with elements, using the add(E e) API method of LinkedHashSet.
  • Invoke iterator() API method of LinkedHashSet, to get an Iterator over the elements in this set. The elements are returned in no particular order.
  • Iterate over the set’s elements with hasNext() and next() API methods of Iterator.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

import java.util.Iterator;
import java.util.LinkedHashSet;
public class LinkedHashSetIterator {
  public static void main(String[] args) {
    // Create a LinkedHashSet and populate it with elements
    LinkedHashSet linkedHashSet = new LinkedHashSet();

    // To get the Iterator use the iterator() operation
    Iterator it = linkedHashSet.iterator();
    System.out.println("Elements in LinkedHashSet :");
