Implement a Single linked list to store a set of Integer numbers (no duplicate)  • Instance variable • Constructor • Accessor and Update methods 3. Define TestSLinkedList Class a. Declare an instance of the Single List class. b. Test all the methods of the Single List class.

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 The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9.  Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.

Instruction: To test the Linked List class, create a new Java class with the main method, generate Linked List using Integer and check whether all methods do what they’re supposed to do. A sample Java class with main method is provided below including output generated. If you encounter errors, note them and try to correct the codes. Post the changes in your code, if any. Additional Instruction: Linked List is a part of the Collection framework present in java.util package, however, to be able to check the complexity of Linked List operations, we can recode the data structure based on Java Documentation https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html package com.linkedlist;   public class linkedListTester {          public static void main(String[] args) {              ListI<Integer> list = new LinkedList<Integer>();              int n=10;              for(int i=0;i<n;i++) {                     list.addFirst(i);              }              for(int…
