Java's LinkedList provides a method listlterator(int index) returning a Listlterator for a list. Declare a variable of LinkedList of integer numbers and write a fragment of Java code to compute and print the sum of the numbers on the list. Do not write code to insert elements to the list and assume that the list already has elements on it. You must only use an iterator obtained from the list (you can not use the get(int index) method) .

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

Write a Java class myLinkedList to simulate a singly linked list using arrays as the underlying structure. Include the following methods: 1. insert an element within the linked list.(this should also work for the front and the rear of the list) 2. Remove an element from the linked list 3. Display (print) the elements of the linked list in order. 4. A method to check if the list is "empty". Test your solution using a linked list that initially has the characters A, B, D, E, F, and G. Insert "C" between B and D. Remove element "F". [Hint: One solution (recommended) is to use 2 arrays. One for the data, and the other for the "next" pointer. Also, consider using dummy nodes for the front, and possibly the rear of the list] Extend the solution so that it simulates a doubly linked list! (hint: You will need a third array to represent the "backward" pointers)
Suppose that you want an operation for the ADT list that adds an array of items to the end of the list. The header of the method could be as follows: public void addAll( T[ ] items) Write an implementation of this method for the class LinearLinkedList
The curly bracket used in java to enclose units of code can not be used in a fill in questions. For this questions the curly brackets will be substituted with comments. Interpret the begin and end comments as curly brackets. Complete the code for the method filter. The method receives two parameter of generic type E called low and high. The method filters the elements within the linked list and return a linked list with all the elements from the low value to the high value. Example: [1,2,4,5,8,9,11,12] Called with low = 2 and high =10 will return [2,4,5,8,91. public //begin method MyLinkedList newlist = 0; Node befPtrD if(this. ==null) return newlist; for (Node clptr= //begin for if && //begin if newlist.append(clptr.element); if( head=head.next; else if(clptr==tail) +ail-bofPtr

Import the ArrayList and List classes from the java.util package to create a list of phone numbers and also import the HashSet and Set classes from the java.util package to create a set of unique prefixes. Create a class called PhoneNumberPrefix with a main method that will contain the code to find the unique prefixes. Create a List called phoneNumbers and use the add method to add several phone numbers to the list. List<String> phoneNumbers = new ArrayList<>(); phoneNumbers.add("555-555-1234"); phoneNumbers.add("555-555-2345"); phoneNumbers.add("555-555-3456"); phoneNumbers.add("444-444-1234"); phoneNumbers.add("333-333-1234"); Create a Set called prefixes and use a for-each loop to iterate over the phoneNumbers list. For each phone number, we use the substring method to extract the first 7 characters, which represent the prefix, and add it to the prefixes set using the add method. Finally, use the println method to print the prefixes set, which will contain all of…

JAVA Write a method called removeLeastValue in the class KWLinkedList (a class for doubly linked list as discussed in the lectures). The method will search for the smallest value in the double linked list of integers and removes the node that contains that value. Assume that the list must contain at least two nodes. Assume further that the smallest value never be in the first node. Do not use Iterators and you are not allowed to call any of the KWLinkedList class methods. Example: Iist (before method call): 7 10 2 3 5 3 9 Iist (after method call): 7 10 3 5 3 9 Method heading: public void removeLeastValue()
