using java programming code the following
Create java program reads words from a text file, creates a ItemNode instance for each word (use type String), adds each NodeItem instance to a SinglyLinkedList class instance, then traverses this list recursively to display the words in the reverse original (FIFO) order they were added in. For instance, if you added the Strings "one", "two", "three" in that order, code the SinglyLinkedList print() method to display "one two three". You can do this by recursively traversing the list, then displaying each item as you return from each activation record. For instance, data "one two" should be displayed as "two one".

Lab 19 Building a linked list Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order: 1. Create a new Node object. 2. Make the data variable in the new Node object reference the object that was passed to addFirst. 3. Make the next variable in the new Node object reference the object that is currently referenced in variable first. 4. Make variable first reference the new Node. Test your code by running the main method in the LinkedListRunner class below. Explain, step by step, why each of the above operations is necessary. Why are the string objects in the reverse order from the way they were added? public class LinkedList { private Node first; public LinkedList () {…
