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.

JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics.   You have been provided with java code for SomeList<T> class.  This code is for a general linked list implementation where the elements are not ordered.  For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back.  You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back.  You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list.  Your code to remove an object must include the exception NoSuchElementException.  Demonstrate your code by displaying the ordered linked list and…

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

Java language Write a method to insert an array of elements at index in a single linked list and then display this list. The method receives this array by parameters

Pythong help!

PYTHON LAB: Inserting an integer in descending order (doubly-linked list) Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1   _____________________________________________________________________________________   Main.py: from IntNode import IntNode from IntList import IntList   if __name__ == "__main__":     int_list = IntList()         input_line = input()     input_strings = input_line.split(' ')         for num_string in input_strings:         # Convert from string to integer         num = int(num_string)           # Insert into linked list in descending order         new_node = IntNode(num)         int_list.insert_in_descending_order(new_node)             int_list.print_int_list() IntNode.py class IntNode:     def __init__(self, initial_data, next = None,…

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

LAB: Finding an integer in a list (singly-linked list)   Given main() and an IntNode class, complete the IntList class by writing the append() and search() methods. The search() method should return the IntNode whose data value matches a given key, and null if the key is not found. The search() method should also set the position of each IntNode searched in the IntList, starting with 1. Ex: If the input is: 12 23 59 37 923 2 -1 12 the output is: 12 found in list at position 1. If the input is: 12 23 59 37 923 2 -1 68 the output is: 68 not found in list.   ______________________________________   import java.util.Scanner; public class SearchList {public static void main (String[] args) {Scanner scnr = new Scanner(System.in);IntList intList = new IntList();IntNode curNode, foundNode;int num, searchNum;num = scnr.nextInt();while (num != -1) {// Insert into linked listcurNode = new IntNode(num);intList.append(curNode);num = scnr.nextInt();}searchNum = scnr.nextInt();foundNode =…
