- Programming in Java. What would the difference be in the node classes for a singly linked list, doubly linked list, and a circular linked list? I attached the node classes I have for single and double, but I feel like I do not change enough? Also, I use identical classes for singular and circular node which does not feel right. Any help would be appreciated.Define and implement a type statsList as a subtype of IntList that provides methods to return mean and variance of the data in the list. Be sure to define abstraction function and repOK (). Add required specifications wherever it is needed. Write a java code Code with comments and output screenshot. Thank you!!!In writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Extend Article class toimplement Comparable interface so that the default sorting of the Articles is by its volume
- Please give a detailed answer and code examples for all of the questions below.What is an array and linked list?What the difference between array and List?Difference between ArrayList and Arrays in Java?Java (Sort, IComparable) The librarian wants to sort the media in the ArrayList by title. For this purpose, the Medium class should implement the Comparable interface. Implement a Method compareTo (...) in the abstract class Medium. Then sort the Media in the ArrayList. Implement the sort method in the Zettelkasten class.This should, by Parameters can be selected, the media contained in descending ("A" → "Z") or ascending ("Z" → Sort "A") by title. Please do not implement your own sorting algorithm, but rather simply use a suitable method of the ArrayList class. Increase the efficiency of the note box. The note box should remember whether the The media contained therein are already sorted, e.g. by calling sort earlier. In this case, re-sorting should be omitted.We have been given a vehicle class (Image 1) that is a domain class in java and we want to create a vehicle service class named VehicleArrayIListlmpl (Image 2). The Service class will store multiple domain objects, support the implementation of the domain class, and include a java collection array list. Use java to create the VehicleArraylListImpl, with appropriate methods (based on the class diagram) Business rule - When adding a Vehicle, confirm the Vehicle is not present. Confirm the Owner does exist. If either does not pass, print a message to the console and stop the add.

- Apply the methods in the ListIterator interface to write a Java program in NetBeans that creates a LinkedList of four elements of type string, namely: Java, C#, PHP and Python. The program should then print out the elements initially in the original order, and then afterwards in reverse order using the ListIterator methods. In this case, the following is the expected output:Write a code in java for bookstore where is object sequentially aggregated, list of book name, year of publication and name of publisher, collected by array list and implement the iteratorJava Code: Below is Parser.java and there are errors. Look at the errors carefully and please fix those errors and show the fixed code.
