JAVA plese Implement the indexOf method in the LinkedIntegerList class public int indexOf(int value); /** * Returns whether the given value exists in the list. * @param value - value to be searched. * @return true if specified value is present in the list, false otherwise. */ } public static void main(String[] args) { // TODO Auto-generated method stub SimpleIntegerListADT myList = null; System.out.println(myList); for(int i=2; i<8; i+=2) { myList.add(i); } System.out.println(myList.index

/ This method takes as parameters a reference to the head of a linked list, a // position specified by n, and a key.

Data Structures/Algorithms in Java

Java Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. 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 Second image is ItemNode

In Java please help with the following: Sees whether this list is empty.@return True if the list is empty, or false if not. */ public boolean isEmpty(); } // end ListInterface Hint:Node class definition should look something like: public class Node<T> { T element; Node next; Node prev; public Node(T element, Node next, Node prev) { this.element = element;this.next = next;this.prev = prev; } }

IN PYTHON THANK YOU

Can you please answer this fast and with correct answer. Thankyou

IN JAVA PLEASE, need help finding an element in the list /** * Returns whether the given value exists in the list. * @param value - value to be searched. * @return true if specified value is present in the list, false otherwise. */ public int indexOf(int value) { //Implement this method return -1; }
