Use the scenario below for help answering 1(A), (B) and (C). This is using Java. The Scenario: You have a class named HeartsPlayer A round of Hearts starts with every player having 13 cards Players then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep) Players then strategically play cards in order to have the lowest score At the end of the round, points are cumulatively totaled for each player. If one player’s total is greater than 100, the game ends and the player with the lowest score wins.

Task 3 Implement the design of the Passenger class so that the following output is produced: The assumption is Bus base-fare is 450 taka. A passenger can carry upto 20 kg for free. 50 taka will be added if bag weight is between 21 and 50 kg. 100 taka will be added if bag weight is greater than 50 kg. [You are not allowed to change the code below] Output: Total Passenger: 0 # Write your code here print(“Total Passenger:", Passenger.count) == Name: Jack p1 = Passenger(“Jack") Bus Fare: 550 taka p1.set_bag_weight(90) ===== !== p2 = Passenger("Carol") Name: Carol Bus Fare: 450 taka p2.set_bag_weight(10) == p3 = Passenger("Mike") Name: Mike p3.set_bag_weight(25) Bus Fare: 500 taka ==== print("== =") %3D Total Passenger: 3 p1.printDetail() print("== ==") p2.printDetail() print("= =") p3.printDetail() print("== ==") print("Total Passenger:", Passenger.count)

7. Write a Temperature class that represents temperatures in degrees in both Celsius and Fahrenheit. Use a floating-point number for the temperature and a character for the scale: either 'C' for Celsius or 'F' for Fahrenheit. The class should have · Four constructors: one for the number of de- grees, one for the scale, one for both the de- grees and the scale, and a default construc- tor. For each of these constructors, assume zero degrees if no value is specified and Cel- sius if no scale is given. · Two accessor methods: one to return the temperature in degrees Celsius, the other to return it in degrees Fahrenheit. Use the for- mulas from Practice Program 5 of Chapter 3 and round to the nearest tenth of a degree. • Three set methods: one to set the number of degrees, one to set the scale, and one to set both. • Three comparison methods: one to test whether two temperatures are equal, one to test whether one temperature is greater than another, and one to test whether one temper-…

Make the following program using JAVA language: Create a class called Bicycle, which has three attributes of integer type: CurrentSpeed, CurrentChainring CurrentGear, and has Four methods: accelerate (), brake (), changeChainring (int chainring), changeGear (int gear), where the first doubles the current speed, the second halves the current speed, and the third and fourth adjust the current chainring and gear respectively according to the received parameters. Create a constructor that initializes all the attributes and create two objects of the bicycle class: myBicycle and yourBicycle
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…
!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilı
