Java. Refer to screenshot. There is starter code for this question. public class LinkedList {Node head;Node tail; protected class Node{String data;Node next;} public String removeFirst(){//Complete the implementation of removeFirst} public String toString(){ String result = ""; Node n = head;while(n != null){result += n.data + " -> ";n = n.next;} return result;} }
Data and links are node class variables. Which boolean expression determines whether two nodes (p and q) have the same numbers? Let p and q be non-null. p.data() q.data() p.link-q.link No answers here
To finish up the definition of the Node class, we need at least two constructor methods. We definitely want a default constructor that creates an emptyNode, with both the Element and Link members set to null. We also need aparameterized constructor that assigns data to the Element member and setsthe Link member to null.Write the code for the Node class:
Two strings, color1 and color2, are read from input as two desks' colors. headObj has the default value of "color". Create a new node firstDesk with string color1 and insert firstDesk after headObj. Then, create a second node secondDesk with string color2 and insert secondDesk after firstDesk. Ex: If the input is gold maroon, then the output is: color gold maroon
A linked list is built in this lab. Make sure to keep track of the head node. ContactNode.java - Class definition ContactList.java - Contains main() method (2) Build the ContactNode class per the following specifications: Private fields String contactName String contactPhoneNumber ContactNode nextNodePtr Constructor with parameters for name followed by phone number Public member methods getName() - Accessor getPhoneNumber() - Accessor insertAfter() getNext() - Accessor printContactNode() Ex: If the name is Roxanne Hughes and the phone number is 443-555-2864, printContactNode() outputs: Name: Roxanne Hughes Phone number: 443-555-2864 (3) Define main() to read the name and phone number for three contacts and output each contact. Create three ContactNodes and use the nodes to build a linked list. Ex: If the input is: Roxanne Hughes 443-555-2864 Juan Alberto Jr. 410-555-9385 Rachel Phillips 310-555-6610 the output is: Person 1: Roxanne Hughes, 443-555-2864 Person 2: Juan…
Given the IntNode class, define the getCount() method in the CustomLinkedList class that returns the number of items in the list not including the head node. Ex: If the list contains: head -> 14 -> 19 -> 4 getCount(headObj) returns 3. Ex: If the list contains: head -> getCount(headObj) returns 0. public class IntNode { private int dataVal; // Node data private IntNode nextNodePtr; // Reference to the next node // Default constructor public IntNode() { dataVal = 0; nextNodePtr = null; } // Constructor public IntNode(int dataInit) { this.dataVal = dataInit; this.nextNodePtr = null; } // Constructor public IntNode(int dataInit, IntNode nextLoc) { this.dataVal = dataInit; this.nextNodePtr = nextLoc; } /* Insert node after this node. Before: this -- next After: this -- node -- next */ public void insertAfter(IntNode nodeLoc) { IntNode tmpNext; tmpNext = this.nextNodePtr;…
starter code: in java pls and thank you! public class LinkedList { private Node head; private Node tail; public void add(String item) { Node newItem = new Node(item); // handles the case where the new item // is the only thing in the list if (head == null) { head = newItem; tail = newItem; return; } tail.next = newItem; tail = newItem; } public void print() { Node current = head; while (current != null) { System.out.println(current.item); current = current.next; } } public void printWithSkips() { // TODO your code here } class Node { String item; Node next; public Node(String item) { this.item = item; this.next = null; } } } and public class Driver { public static void…
Assume a Node class has been defined using the Node class implementation in your textbook, except that the data members have been declared public instead of private. This means that the code shown below has direct access to the data members defined inside the Node class. Type the exact output produced by the following code fragment. Assume that the code compiles and executes without errors. void linkedList (void) { Node<char> *ptr1; Node<char> *ptr2; Node<char> *top; char ch; ptr1 = new Node<char>; top = ptr1; ptr1->item = 'D'; ptr1 = new Node<char>; top->next = ptr1; ptr1->item = 'E'; for (ch = 'H'; ch < 'P'; ch = ch + 3) { ptr2 = new Node<char>; ptr1->next = ptr2; ptr2->item = ch; ptr1 = ptr1->next; ptr2 = new Node<char>; ptr1->next = ptr2; ptr2->item = ch + 1; ptr1 =…

Write a method that takes a pointer to a Node structure as a parameter and returns a complete copy of the passed in data structure. The Node data structure contains two pointers to other Nodes.
You will be given a Linked List of Integers. Remove all even numbers, and then print the Linked List. You are not allowed to use any data structure other than a custom built linked list. This should consist ONLY of a node class. You should not be creating a secondary class to handle the data structure. public class Node { private E item; private Node next; public Node(E item, Node next) { this.item = item; this.next = next; } public E getItem() { return item; } public void setItem(E item) { this.item = item; } public Node getNext() { return next; } public void setNext(Node next) { this.next = next; } } public Node removeInts(Node linkedList) { return null; // Return the start node of your linked list as well as printing it. }
What happens when a programmer attempts to access a node's data fields when the node variable refers to None? How do you guard against it? *PYTHON
