- Java - The node (22, 24, 26) is split. Enter each node's keys after the split, or "none" if the node doesn't exist.Don't copy from anywhere... please fast... typed answer Assignment: Linked List of Students You have been tasked with implementing a program in Java that uses a linked list to store and manage a list of students in a class. Each student should have a name and a grade. Your program should include the following classes: Student: Represents a student in the class. Each student should have a name and a grade. Node: Represents a node in the linked list. Each node should store a reference to a student and a reference to the next node in the list. LinkedList: Represents the linked list itself. Each linked list should have a reference to the first node in the list. Your task is to implement these classes using a linked list and demonstrate their functionality by creating a console-based interface for users to interact with the system. Your program should allow users to: Add a new student to the class at the end of the list. View information about a student, including their name and grade.…What is the simplest approach for me to fix a Node Constructor in my Java program? The current issue is that it does not accept the Object that is supplied to it.
- In this lab the task is to write a program that maintains a personal phone book. The program allows to: ▪ Add and Delete entries from the phone book, ▪ Search the phone book for a specific entry by last name or by phone number, and ▪ Print out the entire entries in the phone book. The data in the phone book is maintained by storing in memory with the use of a singly linked list, with one list node per entry. Each node contains members for storing a person’s family name, first name, address, and the phone number. Use strings to store this information. The linked list must be kept in increasing alphabetical order, sorted by family name. There are no duplicate entries with the same family name allowed in the phone book. This program should be menu driven, with the user being offered a choice of the following commands described below: ▪ Insert a new entry into the phone book. The program should prompt the user for a new family name and first name, an address and a phone number. This…JavaScript The jQuery "post" method that we used in this course to enable "round-trip" dialog with the node.js server has the form: $.post("/", x, y); Describe the type and purpose of the x and y parameters.The programming language is Python Instructions: Create a function that will delete a node in a Linked List based on position number. On below example, if you want to delete position #2, it will remove the Banana (arrangement of nodes below is Apple, Banana, Cherry, Grapes, Orange). myLinkedList = LinkedList() myLinkedList.append("Banana") myLinkedList.append("Cherry") myLinkedList.append("Grapes") myLinkedList.append("Orange") myLinkedList.prepend("Apple") myLinkedList.deleteByPositionNum(2) node = myLinkedList.head while node: print(node.value, " ") node = node.next_node You may start with the function head:def deleteByPositionNum(self, positionNum):
- Write a Java program that creates and maintains a binary search tree (BST) whose nodes are student records. Each student record (BST node) contains the student's id (String), name (String) and GPA (float). Use the student id as a key for the BST. The program starts with an empty BST and offers the following menu options to the user repeatedly until the user selects the 'Q' option (quit). A: Add a new student record to the BST. Here the user is prompted to enter the new student’s id, name and GPA. The program should display an error message if the student id already exists in the BST. F: Find a student record. Here the user is prompted to enter the id of the student to be searched. If found the program displays the student id, name and GPA, otherwise the program displays an error message. D: Delete a student record. Here the user is prompted to enter the id of the student record to be deleted. The program should display an error message if the student id is not found in the BST. P:…What is the easiest way to fix a Node Constructor in my Java program? The current problem is it does not accept the Object being passed into it.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() { first = null; } public Object…
