Program: How to copy or clone a LinkedList?


Description:

Here we can see example for creating duplicate object of an LinkedList instance. we can done this by using clone() function.


Code:
package com.java2novice.linkedlist;

import java.util.LinkedList;

public class MyLinkedListClone {

	public static void main(String a[]){
		
		LinkedList<String> arrl = new LinkedList<String>();
		//adding elements to the end
		arrl.add("First");
		arrl.add("Second");
		arrl.add("Third");
		arrl.add("Random");
		System.out.println("Actual LinkedList:"+arrl);
		LinkedList<String> copy = (LinkedList<String>) arrl.clone();
		System.out.println("Cloned LinkedList:"+copy);
	}
}

Output:
Actual LinkedList:[First, Second, Third, Random]
Cloned LinkedList:[First, Second, Third, Random]

Where can we use serialization?
Whenever an object has to sent over the network, those objects should be serialized. Also if the state of an object is to be saved, objects need to be serilazed.
