- Part 2: Sorting the WorkOrders via dates Another error that will still be showing is that there is not Comparable/compareTo() method setup on the WorkOrder class file. That is something you need to fix and code. Implement the use of the Comparable interface and add the compareTo() method to the WorkOrder class. The compareTo() method will take a little work here. We are going to compare via the date of the work order. The dates of the WorkOrder are saved in a MM-DD-YYYY format. There is a dash '-' in between each part of the date. You will need to split both the current object's date and the date sent through the compareTo() parameters. You will have three things to compare against. You first need to check the year. If the years are the same value then you need to go another step to check the months, otherwise you compare them with less than or greater than and return the corresponding value. If you have to check the months it would be the same for years. If the months are the same you…DirectionsThe total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. For this practice problem you will need to download Shopping Trip Starting Code.zip The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately.Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any change at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present. Make sure that it is for anygiven…Can you implement the Student class using the concepts of encapsulation? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. You are given a Student class in the editor. Your task is to add two fields: ● String name ● String rollNumber and provide getter/setters for these fields: ● getName ● setName ● getRollNumber ● setRollNumber Implement this class according to the rules of encapsulation. Input # Checking all fields and getters/setters Output # Expecting perfectly defined fields and getter/setters. There is no need to add constructors in this class.

Your client code should give the user the option to: display the contents of the bag using the class method “toVector” add values to the bag remove values from the bag sort the bag search for a value using their choice of either the iterative search or the recursive search - both need to be tested Allow the user to keep doing these things until they are done. Do not automatically sort the bag if the user chooses to search. Your program should give the user a message telling them they must first sort the bag before they can search.You decide what the user interface will be. Make it clear and easy to use. It can be very basic; nothing fancy. A menu driven program works well. Each value in your array should be unique - no value will appear in the array multiple times. Your array elements can be any data type – use a template class put in place in the code provided. You can write your client code to process a bag holding any…
- java please dont take other website'answer. rthis is actually practice question ANIMALCLASS Create an Animal class. Each animal has a name, an x and y integer coordinate. The Animal class should have at minimum the following methodsbelowbut you may want to add more if necessary: Also note, everyanimal will need to have to have “z”passed to it so that it knows how big the map is. •A constructor that starts the animal at 0,0 with a name of "Unknown Animal"and only accepts a single int value (int mapSize). •A parameter constructor that allows the programmerto input all 4pieces of information.(x,y, name, mapSize)oCheck the parameters for valid input based on the constraints. Ifany of the input valuesis invalid, adjust it any way you deem necessary in order to make it valid. •getX()and getY() •getName() •toString(). o This should print out the name and coordinates of the animal. •touching(Animal x) This method should determine if the animal is on the same spot as a secondanimal(x). It…Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } } public class Student { private String first; // first name private String last; // last name private…He works in a car dealership. A man approached and said he could not believe that electric cars existed. He intends to prove her wrong. You go to the scene and check out the first car. You discard the first two items when they are not electric, although there may be gas cars going on down the line that proved your point and in this case, they can restore the list of remaining cars. Examples good users = [ {"user": "barney", "active": false}, {"user": "fred", "active": false}, {"user": "pebbles", "active": true} dropWhile (users, function (o) {return! o.active;}) [{"user": "stones", "active": true}]
- pet shop wants to give a discount to its clients if they buy one or more pets and at least five other items. The discount is equal to 20 percent of the cost of the other items, but not the pets.Use a class Item to describe an item, with any needed methods and a constructor public Item(double price, boolean isPet, int quantity)An invoice holds a collection of Item objects; use an array list to store them. In the Invoice class, implement methods public void add(Item anItem)public double getDiscount()Write a program that prompts a cashier to enter each price and quantity, and then a Y for a pet or N for another item. Use a price of –1 as a sentinel. In the loop, call the add method; after the loop, call the getDiscount method and display the returned value.This is the question that is confusing me - A. Create a CollegeCourse class. The class contains fields for the course ID (for example, CIS 210), credit hours (for example, 3), and a letter grade (for example, A). Include get and set methods for each field. Create a Student class containing an ID number and an array of five CollegeCourse objects. Create a get and set method for the Student ID number. Also create a get method that returns one of the Student’s CollegeCourses; the method takes an integer argument and returns the CollegeCourse in that position (0 through 4). Next, create a set method that sets the value of one of the Student’s CollegeCourse objects; the method takes two arguments—a CollegeCourse and an integer representing the CollegeCourse’s position (0 through 4). B. Write an application that prompts a professor to enter grades for five different courses each for 10 students. Prompt the professor to enter data for one student at a time, including student ID and course…If answered wrong i will downvote it
