Chapter 5, Problem 10PP
Consider a class Movie that contains information about a movie. The class has the following attributes:
Solution to Project 10
- The movie name
- The MPAA rating (e.g., G, PG, PG-13, R)
- The number of people who have rated this movie as a 1 (Terrible)
- The number of people who have rated this movie as a 2 (Bad)
- The number of people who have rated this movie as a 3 (OK)
- The number of people who have rated this movie as a 4 (Good)
- The number of people who have rated this movie as a 5 (Great)
Implement the class with accessors and mutators for the movie name and MPAA rating. Write a method addRating that takes an integer as an input parameter. The method should verify that the parameter is a number between 1 and 5, and if so, increment by one the number of people rating the movie that matches the input parameter. For example, if 3 is the input parameter, then the number of people who rated the movie as a 3 should be incremented by one. Write another method, getAverage, that returns the average value for all of the movie ratings. Test the class by writing a main method that creates at least two movie objects, adds at least five ratings for each movie, and outputs the movie name, MPAA rating, and average rating for each movie object.

Consider a class Movie that contains the following information about a movie. The class has the following attributes:
Title
MPAA Rating (e.g. G, PG, PG-13, R)
Number of people who rated this movie as a 1 (Terrible)
Number of people who rated this movie as a 2 (Bad)
Number of people who rated this movie as a 3 (OK)
Number of people who rated this movie as a 4 (Good)
Number of people who rated this movie as a 5 (Great)
Implement the Movie class such that it is able to contain the above information. Include constructor that would accept two parameters and initialize the movie's title to the value of its first parameter and the movie's MPAA rating to the value of its second parameter, and public rating to 0. Also include access member functions for title and MPAA rating. Include a member function to increment the public rating that will only accept integer values
between 1 and 5. Finally, write a member function that would return the average public rating of a movie.

Create a Class Pet with the following data members
Identification: String
species : String (e.g. cat, dog, fish etc)
breed: String
Age (in days): int
Weight: float
Dead: boolean
1. Provide a constructor with parameters for all instance variables.
2. Provide getters for all and setters for only breed, and weight
3. Provide a method growOld() that increases the age of the pet by one day. A dead pet wont grow old
4. Provide a method growHealthy(float w) that increases the weight of the pet by the given amount w. A dead pet cannot grow healthy.
5. Provide a method fallSick(float w) that reduces the weight of the pet by the given amount. The least weight a pet can have is 0 which will mean that the pet has died. If the value of weigh is 10 kg and the method is called with an argument of 11 kg then you will set it to 0 and set the dead to an appropriate value to mark the death of the pet
6. Provide a toString method that shows an appropriate well formatted string…

- Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1.

Let's say we want to store the following information about this book: The book's name The book's author(s) (a book can have more than one author) The book's publisher The book's ISBN number The book's price The book's year of publication First, answer the following questions before the design: 1.

It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230arrow_forward

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…arrow_forward

We want to be able to create a new bank account, make deposits and withdrawals, and check the balance.

We should also be able to retrieve the account id and the name on the account. Provide a constructor that takes a name for the account as a parameter. Remember that a constructor has the same name as the class. The constructor should initialize all of the instance variables. What does the class need to remember? Those are the instance variables. There should be three.
