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.

For this project, you will create a class for an elementary school that will allow a teacher to enter each student's seating assignment. Occasionally, the teacher may need to switch
the seating assignment of a student. If there is a seat available, the student is moved. If all of the seats are already assigned, the teacher will have two students trade seats.
Minimum Requirements:
• Create a class called student that holds information about one student including the student's name. The class must have methods to set each instance variable and methods to
get each instance variable.
• Create a class called seatingChart and create a multidimensional array of student objects as an instance member. The array of student objects should be able to handle a class
of size 20. You will not get credit for this assignment if you do not use a multidimensional array for the seating chart.
• Include an addStudent function that has parameters for a student name, target seat row and column to add one…
Consider a class Movie that contains the following information about a
movie:
* Title
* MPAA Rating (e.g. G, PG, PG-13, R)
* Number of people who rated this movie as a 1
Number of people who rated this movie as a 2
* Number of people who rated this movie as a 3
* Number of people who rated this movie as a 4
* Number of people who rated this movie as a 5
Implement the Movie class such that it is able to contain the above
information. Include a 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 accessor 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.
Write a program that would use your Movie class by first asking the user to
input…

Create a "Car" class that keeps car ids and prices. And create a "Galleries" class that holds the car list for a particular gallery. In this class there should be methods for get / set and print for car name, car number and car list. Adding / Removing Cars to the List in This Class should have methods. And create another method to find and print the IDs of Cars with Car Segment equal to X. (print (X)).
Car Prices are as follows according to the segments.
0-19999 -> Z20000-29999 -> Y30000-44999 -> T45000-100000 -> P
Apply the Car list using "Single Linked List"(Node, newNode, head).
The program should be written in JAVA.

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.

- In this activity, we are going to plan out and write a class definition that stores information for a book. 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.

Add a constructer without parameters to initialize all the attributes to default values (0 for numbers, "" for a string and null for object). Add a second constructer to initialize all the attributes to specific values. Use the keyword "this". Add the method changePrice that change the price of a product. The method must display an error message if the given price is negative. Add a static method changeShopName to change the shop name. Add all the getter methods.

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
- The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. 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_forwardCreate a class “Pizza”, and three sub-classes “Cheese Pizza”, “Pepperoni Pizza” and “VeggiePizza”.
