Using OOP in java   Create a class called Employee that includes three pieces of information as instance variables—a first name (typeString), a last name (typeString) and a monthly salary (double).Provide a set and a get method for each instance variable.Keep in mind you should get values from user.There should be a method called calculateSalary() witch deducts the income tax from the salary on the following basis:   20% income tax if the salary is above Rs 30000.   15% income tax if the salary is between Rs.20000 and Rs.30000.   10% income tax if the salary is below Rs. 20000.   Write a test application named EmployeeTest that demonstrates class Employee’s capabilities. Create Employee objects and display each object’s  full name ,salary , income tax and net salary of  employees.

In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

For this assignment, you will develop the planning necessary for constructing a class that implements a Bag ADT in Java. Your program will store corresponding items for an On-Line Food Delivery Service. Specifically, your program should consider an item's name and price and manage the customer's shopping cart. The following are example values your class will be using for data: Customer Number = 1; item_Name="Can of Soup"; Price = $4.00; After selecting your values for data, what are the required operations that must be used to create the Bag Interface? Your deliverable will consist of the following: Pseudocode for your proposed program Flowchart of the operations of adding items to the shopping cart and removing items from the cart.

C++ Programming. Create a "Stool' class. Fields: height (h, cm), product quality (low, medium, high). Specify two virtual methods: The "Wood amount" method determines the amount of wood that goes into the stool: 4 • h + 12 if the product quality is low, 5 • h + 14 if the quality is average or high. "Price" method is equal to d • 2 for low quality, d • 3 for medium quality, d • 4 for high quality, where d is the amount of wood required for the object. Also write an "Information" method that prints information about the object: Height, Material Quality, Wood Quantity, and Price. Also create an inheritance class "Chair". Additional area: back height (h2, cm). In the reloaded "Amount of Wood" method, the amount of wood is calculated using the formula d + 2 • h2 + 5.

JAVA PROGRAM Chapter 7. PC #1. Rainfall Class Write a RainFall class that stores the total rainfall for each of 12 months into an array of doubles. The program should have methods that return the following: • the total rainfall for the year • the average monthly rainfall • the month with the most rain • the month with the least rain Demonstrate the class in a complete program. Main class name: RainFall (no package name)   HERE IS  A WORKING CODE, PLEASE MODIFY THIS CODE SO THE PUBLIC CLASS IS MAIN AND WERE EVER THERE IS MAIN IN THE CHANGE IT SO IT RUNS. ALSO, MAKE SURE WHEN I UPLOAD THE CODE TO HYPERGRADE IT PASSES ALL THE TEST CASES. THANK YOU   import java.util.Scanner;public class Main {        private double[] rainfall = new double[12];    public Main(double[] rainfall) {        this.rainfall = rainfall;    }    public double getTotalRainfall() {        double total = 0.0;        for(double rain : rainfall) {            total += rain;        }…

The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }

The class provided represents a car. Information about a car includes the brand name of the car and the year it was manufactured. When ordering cars they are ordered in descending alphabetical order by their brand name (z-a). If cars have the same brand name then they are ordered in ascending order by their year. Here is an example of some ordered cars: 2019 Toyota 2012 Subaru 2017 Subaru 2019 Mazda 2018 Kia The Car class is missing a required method. Write the missing method in the space provided below. public class Car implements Comparable { private String brand; private int year; public Car (String brandIn, int yearIn) { brand= brandIn; year = yearIn; } //Write the missing method for this class here.
