how to copy or clone linked list in java?


LinkedList:

The LinkedList class extends AbstractSequentialList and implements the List and Deque interface. It uses linked list data structure to store elements. It can contain duplicate elements. It is not synchronized.

Note: It not provides the random access facility.

We can use clone() method to copy or clone linked list in java.

Example:

package com.codesjava;
 
import java.util.LinkedList;
 
public class Test {
  public static void main(String args[]){
	LinkedList<String> linkedList = new LinkedList<String>();
	linkedList.add("Jai");
	linkedList.add("Mahesh");
	linkedList.add("Naren");
	linkedList.add("Vivek");
	linkedList.add("Vishal");
	linkedList.add("Hemant");
	System.out.println("Actual LinkedList:"+linkedList);
        LinkedList<String> copy = (LinkedList<String>) linkedList.clone();
        System.out.println("Cloned LinkedList:"+copy);
  }
}

Output

Actual LinkedList:[Jai, Mahesh, Naren, Vivek, Vishal, Hemant]
Cloned LinkedList:[Jai, Mahesh, Naren, Vivek, Vishal, Hemant]
