Cruise Recreational Activities Example Recreational activities include things like aerobics, shuffle board, and swimming. Each activity is identified by an activity code and includes other information such as description. Classes are offered for each activity. A class is uniquely identified by a combination of the activity code and the day/time at which it is held. It is assumed that a specific class will never be offered for the same activity at the same day and time, although it could be offered on a different day and/or time. Other information about a class includes the enrollment limit and the current enrollment count. A class will never include more than one activity. A passenger can sign up for a class as long as there is sufficient room in the class. Passengers are identified by a unique passenger number. Other information stored about passengers includes name, address, and age. Passengers have no limit on the number and type of classes they can sign up for. When they…
Design a Ship class that has the following members: A member variable for the name of the ship (a string) A member variable for the year that the ship was built (a string) A default and parameterized constructor and appropriate getters and setters. A toString method that displays the ship’s name and the year it was built. Design a CruiseShip class that is derived from the Ship class. The CruiseShip class should have the following members: A member variable for the maximum number of passengers (an int) A default and parameterized constructor and appropriate getters and setters. A toString method that overrides the toString function in the base class. The CruiseShip class’s toString function should display only the ship’s name and the maximum number of passengers. Design a CargoShip class that is derived from the Ship class. The CargoShip class should have the following members: A member variable for the cargo capacity in tonnage (an int). A default and parameterized constructor and…

8. Circle ClassWrite a Circle class that has the following member variables:• radius: a double• pi: a double initialized with the value 3.14159The class should have the following member functions:• Default Constructor. A default constructor that sets radius to 0.0.• Constructor. Accepts the radius of the circle as an argument.• setRadius. A mutator function for the radius variable.• getRadius. An accessor function for the radius variable.• getArea. Returns the area of the circle, which is calculated as area = pi * radius * radius• getDiameter. Returns the diameter of the circle, which is calculated as diameter = radius * 2• getCircumference. Returns the circumference of the circle, which is calculated as circumference = 2 * pi * radiusWrite a program that demonstrates the Circle class by asking the user for the circle’s radius, creating a Circle object, and then reporting the circle’s area, diameter, and circumference.…
Object composition is useful for creating a(n) _____relationship between two classes.
There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.
Class object method This program has three methods and two constructorsone constructor has one parameter and the other none The class has two primitive variables one static and the other notThe static member is initialized to greater than 0 the non-static to 0 Variables in two methods are assigned with the static member main() has an initialized variable with a value not the same as others in the program; it is used as the argument to one of the constructors; this value is used to assign a value to the static class variable The constructor that takes no argument has a variable declared with the same name as the static variable, it is initialize by the non-static variable A.Demonstrate and explain the displayed results of objects created in the following order Constructor(arg)Constructor() B.Create a second program to Demonstrate and explain Constructor()Constructor(arg) Iolecnotes Assignment 4.

C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().
||| Part 1 Create a UML class diagram for the Time class as described below: The class will have two integer instance variables representing hours and minutes. These will be stored in standard 24-hour time. The class must have the following methods: • a default constructor that sets the time to midnight a constructor that takes two integer variables representing the hours in 24- hour time (0-23) and the minutes in the range 0-59. This constructor will validate the constructor inputs and will set the time to midnight if either value is outside of the needed range. a constructor that takes two integers and a string. The string must be either "AM" or "PM", and the integer will be the hours in the range 1-12 and the minutes in the range 0-60. Again, the constructor will validate the constructor inputs and will set the time to midnight if either value is outside of the needed range or the String is not "AM", "am", "PM", or "pm". getters and setters for the hours and minutes. The setters…

Problem: Employee and ProductionWorker Classes Write a python class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • Shift number (an integer, such as 1, 2, or 3)• Hourly pay rateThe workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for this class. Once you have written the class, write a program that creates an object of the ProductionWorker class, and prompts the user to enter data for each of the object’s data attributes. Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen Note: The program should be written in python.
