- Write a method called addBiggest to be considered in a class outside the KWArrayList class. This method will have a parameter list of class type KWArrayList. The method will add the biggest element of the list, at the end of the 1ist. Method heading: public static void addBiggest (KWArrayList list). Before run: 35 100 40 67 22 After run: 3 5 100 40 67 22 100Write a method called compareSum to be considered in a class outside the KWArrayList class. This method has a parameter list of class type KWArrayList . The method finds the summation of even elements for the first half of list and the summation of odd elements for the second half of list, then compares between the two summations and returns the greater sum. Assume the length of List is even. Method heading: public static int compareSum( KWArrayList<Integer> list) Before run: list= 10 5 50 3 14 33 20 5 (note: the numbers in bold represent the first half) After run: list= 3 5 50 14 33 20 5 Sum1 (for the first half) = 60 Sum2 (for the second half) = 38 Returned value is 60Write a method called compare Sum to be considered in a class outside the KWArrayList class.

- Computer Science create a method +addToList(o:E):void that adds the object (o) to the ArrayList referenced by the instance variable list. create a method +removeFromBackOfList():E that removes the object at the back of the ArrayList and returns it.Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…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;…
- Write the definitions of the member functions of the classes arrayListType and unorderedArrayListType that are not given in this chapter. The specific methods that need to be implemented are listed below. Implement the following methods in arrayListType.h: isEmpty isFull listSize maxListSize clearList Copy constructor Implement the following method in unorderedArrayListType.h insertAt Also, write a program (in main.cpp) to test your function.Java Write a java program that calls a method called removeZeroes that takes as a parameter anArrayList of integers and eliminates any occurrences of the number 0 from the list. For example,if the list stores the values [0, 4, 5, 0, 6, 0, 1] before the method is called, it should store the values [4, 5, 6, 1] after the method finishes executing. Print the ArrayList before and after the method call.A business that sells dog food keeps information about its dog food products in a linked list. The list is named dogFoodList. (This means dogFoodList points to the first node in the list.) A node in the list contains the name of the dog food (a String), a dog food ID (also a String) and the price (a double.) a.) Create a class for a node in the list. b.) Use this class to write pseudocode or Java for a public method that prints the name of all dog foods in the list where the price is more than $20.00.
- Create the Median class that has the method calculateMedian that calculates the median of the integers passed to the method. Use method overloading so that this method can accept anywhere from two to five parameters. How to calculate medianThe median can be thought of as the "middle" number in an ordered list of numbers. There are two numbers in the "middle", the median is the average of these two numbers. Method Call Return Value m.calculateMedian(3, 5, 1, 4, 2) 3.0 m.calculateMedian(8, 6, 4, 2) 5.0 m.calculateMedian(9, 3, 7) 7.0 m.calculateMedian(5, 2) 3.5 Hint Finding the median requires that the numbers be in order. You can use the method Arrays.sort(myArray); to sort an array of integers.Question 11 Write a method called changeQueue to be considered inside the ArrayQueue class and has one parameter item of type E. Your method will change the queue in such a way that if the the first element of the queue and the last element of the queue are equal, the first and last elements in the queue will be replaced with item, otherwise, do not do any change. Similarly, the same process is done for the second element in the queue and the element before the last in the queue and so on. Assume you have a non-empty queue with even number of elements. You are not allowed to call any method from the the ArrayQueue class. Do not use iterators. Method head: public void changeQueue(E item) Example1: Before run: front rear "this" queue: 10 29 2 25 10 Item1: 100 After run: front rear "this" queue: 100 29 100 100 5 100 Use the editor to format your answerPart #1: Write a method called equallists in a class called compare. The method accepts three ArrayList objects list1, list2 and list3 of type ArrayList as parameters. The list3 is to be generated by compare the list1 and list2 by the method, if both lists list1 items and list2 items are equal then write 1 in the same index in list3, else write 0. public class compare { public static boolean equallists mmmmmmmmm (ArrayList unnammmmm ArrayList list3) mmmmmmmmmmm Example: list1: 4 13 1 8 list2: 4 2 1 12 list3: 1 0 1 0 (generated by the method) listl, ArrayList Part #2: Write a class called Test equallists having main method to test the application. In main method create following: 1- Object of type ArrayList list1. 2- Add the following data to list1 (4 13 3- Object of type ArrayList list2. 4- Add the following data to list2 (4 5- Object of type ArrayList list3. 6- Test the equallists method to print the result. 1 9 0 9 0 1 2 05 0 10 2 list2, 18 1 901). 1 12 9 2 0 5).
