LinkedHashMap Iterator example

In this example we shall show you how to obtain a LinkedHashMap Iterator, that is an iterator over the LinkedHashMap key value pairs. To obtain a LinkedHashMap Iterator one should perform the following steps:

  • Create a new LinkedHashMap.
  • Populate the linkedHashMap with elements, with put(K key, V value) API method of LinkedHashMap.
  • Invoke entrySet() API method of LinkedHashMap. It returns a Set with the key- value pairs that the linkedHashMap contains.
  • Invoke iterator() API method of Set, to obtain the Set iterator.
  • Iterate through the linkedHashMap entries, with hasNext() anf next() API methods of Iterator,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;
import java.util.Iterator;
import java.util.LinkedHashMap;
import java.util.Set;
public class LinkedHashMapIterator {
  public static void main(String[] args) {

// Create a LinkedHashMap and populate it with elements

LinkedHashMap linkedHashMap = new LinkedHashMap();




// Get a set of all the entries (key - value pairs) contained in the LinkesHashMap

Set entrySet = linkedHashMap.entrySet();

// Obtain an Iterator for the entries Set

Iterator it = entrySet.iterator();

// Iterate through LinkedHashMap entries

System.out.println("LinkedHashMap entries : ");
