- Create a class BeautyProduct with name, color, brand. Provide Constructors, getters, setters and also write toString method. Now create a class Lipstick which extends the class BeautyProduct as Lipstick is-a Beauty Product it has totalVolume, remainingVolume, price, texture (gloss, matt) as private data members. Provide Constructors, getters, setters and an apply() method whenever this method is called a beauty item is applied and its volume decreases by 10.This should also check that volume must not be zero if it then u have to throw exception. Also write toString method which prints all details like name, color, brand, price, texture and volume. Create another class foundation having totalVolume, remainingVolume, price, texture (liquid, cake) and lastingTime (number of hours foundation remain intact on face and does not crease) as private data members. This also extends the base class i.e. BeautyProduct. Provide Constructors, getters, setters and an apply() method whenever this…Write the Movie class. The UML diagram of the class is represented below: 1. Implement the class strictly according to its UML one-to-one (do not include anythingextra, and do not miss any data fields or methods). 2. Implement a MovieTest class to test the class Movie you just created.• Create two Movie objects: one using the no-args constructor and one from theconstructor with all fields.• Print the contents of both objects. Please submit a screenshot. Hint: toString()method.Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. A data field radius with a get method. A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b). A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. Figure (a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another circle. Draw the UML diagram for the class.…

Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun…
- Exercise (Section 30/40): Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An appointment has a description (for example, "see the dentist") and a date. Write a method occursOn(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Give the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.Part 1: Abstract Classes 1. Copy the source files of Circle, Rectangle and GeometricObject classes (located in LabFiles folder) and paste them in the default package (You may need to fix any problems related to package declaration). 2. Open Circle, Rectangle and GeometricObject classes using NetBeans editor and go through the classes’ implementation. 3. In the GeometricObject class add two methods called respectively getArea() and getPerimeter(). Discuss: 1. Is the area formula of a circle similar to area formula of a rectangle? Since: GeometricObject is the superclass of Circle and Rectangle, and getArea() method is a common method in both Circle and Rectangle classes. Then: 2. Should you define the getArea() method in the superclass GeometricObject? Or in the subclasses Circle and Rectangle? 3. If yes, Should the getArea() method be declared as abstract method in the superclass GeometricObject? Or as instant method? 4. Is declaring getArea() as abstract, would solve…Create a class Animal Create a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal (String name) //constructor public void makes Sound () with the implementation printing out a generic animal sound. Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. (you should observe the makeSound method called will be: cat -> from Cat class, dog-> from Dog class, bearded Dragon -> from Animal class ) EC:…
- Write a derived class of the NumberGuesser class named RandomNumberGuesser. The derived class should override the behavior of the getCurrentGuess method. It may also add member data and its own constructor. It may also override the higher(), lower() and reset() methods as you see fit. To get everyone started off on the same page I have written a NumberGuesser class. It is defined entirely in-line in the following file: NumberGuesser.h (Links to an external site.) In the current NumberGuesser class the getCurrentGuess() method returns the midpoint of the range of possible values. In your RandomNumberGuesser class the getCurrentGuess() method should return a randomly generated number in the range of possible values. Note that repeated calls to getCurrentGuess() should always return the same value for both classes if neither the higher() or the lower() functions are called. Consider the following example: NumberGuesser *ng = new NumberGuesser(1, 10);cout <<…Write the source code of the class Passenger. A passenger can travel with an infant (i.e. his/her child). Code the class Infant as an inner class of the class Passenger.

Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.
