- If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(1). True or False If N represents the number of elements in the list, then the index-based add method of the ABList class is O(N). True or FalseTrying this again since part of my question keeps disappearing 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 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…using arrays or Arraylist in Java language Write the method filterBySize().* * Given an ArrayList of String, return a new list where only * strings of the given length are retained.* * Examples:* filterBySize(["a", "bb", "b", "ccc"], 1) returns ["a", "b"]* filterBySize(["a", "bb", "b", "ccc"], 3) returns ["ccc"]* filterBySize(["a", "bb", "b", "ccc"], 4) returns []* * @param list the list of Strings to process.* @param n the size of words to retain.* @return a new list of words with the indicated size retained.
- Using JAVA, write a method that modifies an ArrayList<String>, moving all strings starting with an uppercase letter to the front, without otherwise changing the order of the elements. Write a test program to demonstrate the correct operation of the method.Write 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.Suppose myGoods is an ArrayList of Product objects. Write the code using an iterator and a while loop to allow you to print all the Products in the list on a single line, separated by spaces
- Design and implement a getLastHalf() method for the MyLinkedList class. The method should return the last half of the list as a new list leaving the original list intact. If the list has an uneven number of elements the extra one element must be in the list returned. Example : [1,3,5,4] return [5,4] and [1,6,9] return [6,9]. Follow the three step method for designing the method Develop the java code for the method Create a test program to test the method thoroughly using the Integer wrapper class.Design and implement a getLastHalf() method for the MyLinkedList class.

For example, if the input listcontains 5, 6, 7, 6, 3, 5, 5, 4 then the output list should have 5, 6, 7, 3, 4.Note: (1) You may assume that the ArrayList has a specific type of elements in it. In the class, we assumedit to have String type values. (2) You may only work with ArrayList(s).
- Consider Bag, SinglyLinkedList, and DoublyLinkedLists classes for integers. Implement and test the following methods: 1. Write a method in Bag class for integers that finds the number of odd and even numbers in the list. 5. Write a method in DoublyLinkedList class that swaps the first and last nodes in the list. 6. Write a Main class to test all these methods.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 ItemNodeFor the following code, indicate the weighted edge values. List<WeightedEdge> list = new ArrayList<>();list.add(new WeightedEdge(1, 2, 3.5));list.add(new WeightedEdge(2, 3, 4.5));WeightedEdge e = java.util.Collections.max(list);e.u = e.v = e.weight =
