LinkedHashMapExample.java
import java.util.LinkedHashMap;

/*
 * Example of clone() method.
 */
public class LinkedHashMapExample
{
    public static void main( String[] args )
    {

        LinkedHashMap<Integer, String> linkedHashMap = new LinkedHashMap<Integer, String>();

        linkedHashMap.put(1, "Apple");
        linkedHashMap.put(3, "Cat");
        linkedHashMap.put(2, "Ball");

        System.out.println("linkedHashMap : " + linkedHashMap + "\n");

        /*
         * Returns a shallow copy of this linkedHashMap instance: the keys and values
         * themselves are not cloned.
         */
        Object object = linkedHashMap.clone();

        System.out
                .println("Object class name : " + object.getClass().getName());

        LinkedHashMap<Integer, String> clonedLinkedHashMap = (LinkedHashMap<Integer, String>) object;

        System.out.println("cloned LinkedHashMap : " + clonedLinkedHashMap);

    }
}
Output
linkedHashMap : {1=Apple, 3=Cat, 2=Ball}

Object class name : java.util.LinkedHashMap
cloned LinkedHashMap : {1=Apple, 3=Cat, 2=Ball}
