Method rotate() in Singly linked list:
//Define the rotate() method
public void rotate()
{
//Check whether the list is empty
if(isEmpty())
//Return it
return;
//Otherwise, execute else statement

Write a java program to Implement the size( ) method for the DoublyLinkedList class, assuming that wedid not keep the size variable as an instance variable.
Implement a method to remove a node from the centre of a singly linked list—that is, any node other than the first and last nodes, not necessarily in that precise order.EXAMPLElnput:the node c from the linked list a->b->c->d->e->fResult: nothing is returned, but the new linked list looks like a ->b->d->e->f
Implement a linked list of integers as aclass LinkedList. Build the following methods:✓ print that prints the content of the linked list;✓ addFirst that adds a new node to the beginning (the head) of thelinked list;✓ addLast that adds a new node to the end (the tail) of the linked list;✓ indexOf that finds a specific node by its value, and returns node’sindex (node’s position from the left in the linked list); if the valueis not present in the linked list, it returns −1;✓ deleteFirst that deletes the first node in the linked list;✓ deleteLast that deletes the last node in the linked list.Test your class creating a list in the main and1) adding one by one nodes 2, 4, 8 to the tail;2) adding nodes -2, -8 to the head;3) adding a node 9 to the tail;4) printing the list;5) printing indexOf(4);6) printing contains(9);7) deleting one by one all the nodes in the list – either from the tail orfrom the head – and printing the result after each deletion.
