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…
basic java please Write a method called findTip that finds the value of a meal as a double after adding the tip to the cost. Then return this value to the calling function. For example findTip(120.10, 5) would 126.105 because that is a 5% tip. While findTip(48.0, 15) would return 55.2 because that is a 15% tip. Note that the bill is a double while the tip is an int. Don’t worry about rounding to two decimal places, just return the full value as a double.
this is for a python class 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is: Name: Apple Price: 0.40 Count: 3 Ex. If 10…
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.

Given main(), define the Team class (in file Team.java). For class method getWinPercentage(), the formula is:wins / (wins + losses). Note: Use casting to prevent integer division. For class method printStanding(), output the win percentage of the team with two digits after the decimal point and whether the team has a winning or losing average. A team has a winning average if the win percentage is 0.5 or greater. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Win percentage: 0.81 Congratulations, Team Ravens has a winning average! Ex: If the input is: Angels 80 82 the output is: Win percentage: 0.49 Team Angels has a losing average.
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; }
