How to iterate LinkedHashMap in Java?

// Java Program to iterate through LinkedHashMap using 
// keySet() and get() Method

import java.util.LinkedHashMap;
import java.util.Set;

public class GFG {

    public static void main(String a[])
    {
        // making the object of LinkedHashMap
        LinkedHashMap<String, String> linkedHashMap
                 = new LinkedHashMap<String, String>();
      
        // adding the elements in linkedHashMap
        linkedHashMap.put("One", "First element");
        linkedHashMap.put("Two", "Second element");
        linkedHashMap.put("Three", "Third element");

        Set<String> keys = linkedHashMap.keySet();
      
        // printing the elements of LinkedHashMap
        for (String key : keys) {
            System.out.println(key + " -- "
                               + linkedHashMap.get(key));
        }
      
    }
}

// Java Program to iterate over linkedHashMap using
// entrySet() and iterator

import java.util.Iterator;
import java.util.LinkedHashMap;
import java.util.Set;

public class GFG {

    public static void main(String[] args)
    {

        // Create a LinkedHashMap and populate it with
        // elements
        LinkedHashMap<String, String> linkedHashMap
            = new LinkedHashMap<String, String>();

        // adding the elements to the linkedHashMap
        linkedHashMap.put("One", "First element");
        linkedHashMap.put("Two", "Second element");
        linkedHashMap.put("Three", "Third element");

        // Get a set of all the entries (key - value pairs)
        // contained in the LinkedHashMap
        Set entrySet = linkedHashMap.entrySet();

        // Obtain an Iterator for the entries Set
        Iterator it = entrySet.iterator();

        // Iterate through LinkedHashMap entries
        System.out.println("LinkedHashMap entries : ");

        while (it.hasNext())
            // iterating over each element using it.next()
            // method
            System.out.println(it.next());
    }
