1) Create all nodes in copy linked list using next pointers. Following diagram shows status of both Linked Lists … Given a Linked list, Clone Linked list in Java. The elements are linked using pointers and addresses. Recursion is a very… Copy linked list in Java. Description: Here we can see example for creating duplicate object of an LinkedList instance. 2) Store the node and its next pointer mappings of original linked list. 3) Change next pointer of all nodes in original linked list to point to the corresponding node in copy linked list. The idea is to iterate over the original list in the usual way and maintain two pointers to keep track of the new list: one head pointer, and one tail pointer which always points to the last node in new list Recursive approach, Iterative approach.

Syntax: LinkedList.clone() Parameters: This method does not take any parameters. Java does not support deep copying by default. Program: How to copy or clone a LinkedList? Linked List is a part of the Collection framework present in java.util package.This class is an implementation of the LinkedList data structure which is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part. The shallow copy is the approach when we only copy field values and therefore the copy might be dependant on the original object. Deep copy of Java class. It just creates a copy of the list. The Java.util.LinkedList.clone() method is used to create a shallow copy of the mentioned linked list. When we want to copy an object in Java, there're two possibilities that we need to consider — a shallow copy and a deep copy. Do a deep copy of a linked list in which each item, in addition to the normal “next” pointer has a random pointer to another item in the list. Deep copy of a Linked List means we do not copy the references of the nodes of the original Linked List rather for each node in the original Linked List a new node is created. 3.1. Return Value: This function returns a copy of the instance of Linked list. So we have to manually modify the code to enable the deep copying of classes and collections. we can done this by using clone() function. Below program illustrate the Java.util.LinkedList.clone() method: In Java, to support deep copy, we must override the clone() of model classes.
