- Practice with writing a program that contains three classes: Ship CruiseShip CargoShip Classes Design a Ship class with the following members: A field for the name of the ship (a string) A field for the year that the ship was built (a string) A constructor that accepts two arguments for the two fields, and appropriate accessors and mutators A toString method that returns a string with the ship’s name and the year it was built Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int) A constructor that accepts three arguments for the three fields and appropriate accessors and mutators A toString method that overrides the toString method in the base class. The CruiseShip class’s toString method should return a string with only the ship’s name and the maximum number of passengers. Design a CargoShip class that extends the Ship class. The CargoShip class should have the…Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class.

- Static variables can... ...can be accessed even without creating an object of that class. ...only be accessed by static methods. ...not be accessed using class prefix. ...not be inherited.TECHNICAL REQUIREMENTS 1. The program must utilize at least two classes. a. One class should be for a player (without a main method). This class should then be able to be instantiated for 1 or more players. b. The second class should have a main method that instantiates two players and controls the play of the game, either with its own methods or by instantiating a game class. c. Depending on the game, a separate class for the game may be useful. Then a class to play the game has the main method that instantiates a game object and 2 or more player objects. 2. The game must utilize arrays or ArrayList in some way. 3. There must be a method that displays the menu of turn options. 4. There must be a method that displays a player's statistics. These statistics should be cumulative if more than one game is played in a row. 5. There must be a method that displays the current status of the game. This will vary between games, but should include some statistics as appropriate for during a game.…Programming Language= PYTHON 3. Personal Information Class Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information. My information: Name: John Doe Address: 111 My Street Age: 22 Phone Number: 555-555-1281 Mom's information: Name: Mom Address: 222 Any Street Age: 52 Phone Number: 555-555-1234 Sis's infomation: Name: Jane Doe Address: 333 Her Street Age: 20 Phone Number: 555-555-4444 Dad's information: Name: Dad Address: 222 Any Street Age: 56 Phone Number: 555-254-5611
- 2. You are to write a program that computes a patient's bill for a hospital stay. different components of the program are The The PatientAccount class The Surgery class The Pharmacy class The main program The PatientAccount class will keep a total of the patient's charges. It will also keep track of the number of days spent in the hospital. The group must decide on the hospital's daily rate. The Surgery class will have stored within it the charges for at least five types of surgery. It can update the charges variable of the PatientAccount class. The Pharmacy class will have stored within it the price of at least five types of medication. It can update the charges variable of the PatientAccount class. The student who designs the main program will design a menu that allows the user to enter a type of surgery and a type of medication, and check the patient out of the hospital. When the patient checks out, the total charges should be displayed.Please help with the following: C# .NET change the main class so that the user is the one that as to put the name in other words. Write a driver class that prompts for the person’s data input, instantiates an object of class HealtProfile and displays the patient’s information from that object by calling the DisplayHealthRecord, method. MAIN CLASS---------------------- static void Main(string[] args) { // Instance created holding 6 parameters which are field with value HealthProfile heartRate = new HealthProfile("James","Kill",1978, 79.5 ,175.5, 2021 ); heartRate.DisplayPatientRecord();// call the patient record method } CLASS HeartProfile------------------- public class HealthProfile { // attibutes which holds the following value private String _FirstName; private String _LastName; private int _BirthYear; private double _Height; private double _Weigth; private int _CurrentYear; public HealthProfile(string firstName, string lastName, int birthYear, double height, double wt, int…Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have: a constructor that accepts arguments for the two fields a method that returns the tract’s area(i.e. length * width) an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false. a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…
- PYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciatedPYTHON PROGRAMMING 1.Create an empty class called Car. 2.Create a method called initialize in the class, which takes a name as input and saves it as a data attribute. 3.Create an instance of the class, and save it in a variable called car. 4.Call the initialize method with the string “Ford".The non-static class level variables and non-static methods of a class are known as a. instance members b. object behaviors c. object attributes O d. object references
