Write a method find() that takes a linked list and a string key as arguments and returns true if some node in the list has key as its item field, false otherwise.
Write a method max() that takes a reference to the first node in a linked list asargument and returns the value of the maximum key in the list. Assume that all keys arepositive integers, and return 0 if the list is empty
Implement a nested class DoubleNode for building doubly-linked lists, whereeach node contains a reference to the item preceding it and the item following it in thelist (null if there is no such item). Then implement static methods for the followingtasks: insert at the beginning, insert at the end, remove from the beginning, removefrom the end, insert before a given node, insert after a given node, and remove a givennode.

- Implement a lastIndex method for the LinkedIntList class you worked on for HW4. This method takes an int argument and returns the largest index such that the int argument appears at that index in the list. If the int argument does not appear in the list, then -1 is returned. For example if the list example contained the numbers [4, -1, 2, 7, -1, 3] in that order, then example.lastIndex(-1) should return 4 and example.lastIndex(5) should return -1. In the text area below, write the definition of the lastIndex method. (In other words, write the code that should replace the //TODO comment.) Your code cannot call any methods. public class LinkedIntList { private class Node { private int item; private Node next; public Node() {} public Node(int number, Node nextNode) { item = number; next = nextNode; } } private Node first; // first node of the list public LinkedIntList() { first = null;…arrow_forwardWrite a program that creates an ArrayList and adds a Loanobject, a Date object, a string, and a Circle object to the list, and use a loop todisplay all the elements in the list by invoking the object’s toString() method.arrow_forwardComplete the method printSkipper below.

DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts public class ItemNode { private String item; private ItemNode nextNodeRef; // Reference to the next node public ItemNode() { item = ""; nextNodeRef = null; } // Constructor public ItemNode(String itemInit) { this.item = itemInit; this.nextNodeRef = null; } // Constructor…arrow_forwardImplement unique method that takes an ArrayList as input and returns an ArrayList withexactly a single occurrence of each element from the input list.
