- In main.py define the Student class that has two attributes: name and gpa Implement the following instance methods: • A constructor that sets name to "Louie" and gpa to 1.0 set_name(self, name) - set student's name to parameter name get_name(self) - return student's name set_gpa(self, gpa) - set student's gpa to parameter gpa get_gpa(self) - return student's gpa Ex. If a new Student object is created, the default output is: Louie/1.0 Ex. If the student's name is set to "Felix" and the gpa is set to 3.7, the output becomes: Felix/3.7arrow_forwardA class called Location.

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

Do not change any of these: Vehicle: an abstract class for any make and model of vehicle that can possibly travel some distance. LimitedRange: an interface for something that has a limit to the distance it can travel. Main: a test program which will work after you have written the code below. Your job is to write the following 3 classes so that this program produces the sample output shown at the end of Main. Specifically you will need: ElectricCar: a vehicle with a limited range. So it must be a subclass of Vehicle, and it must implement LimitedRange. Thus it needs an instance variable for its range, and a travel method (required by Vehicle. Please use @Override) that outputs "Zoom!" if it has enough range to go the distance specified (and update its range). It must have a constructor with 3 arguments as called by main. (Remember that the first line of the constructor must be a call to "super": Vehicle's constructor…arrow_forwardWrite a second constructor as indicated.

- It not complex please don't reject it. give code of it. Wrong answer downvote surearrow_forwardIn c++ Create a new project named lab7_2. You’re going to write a class of your choice! The class should contain: A default constructor and a constructor with parameters for all your member variables. Setters and getters for all member variables. A method that prints out information about your class’s member variables. Your class should again try to minimize the number of methods that modify private member variables. Don’t repeat code! You will create an object of your class type in the driver file. I would like you to create this object on the heap! So your declaration for it should look like: SomeClass* someClassPtr = new SomeClass; Now, you will have to remember that before you can access methods, you need to dereference the pointer to your object. You will recall that using the arrow operator (->) facilitates this kind of access. someClassPtr->someMethod(); At the end of your program, don’t forget to delete your pointer: delete someClassPtr;arrow_forwardThe Essay class has a default constructor, a constructor with two parameters, and a constructor with three parameters.

- Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g Carbohydrates:…arrow_forwardC++ Programming. Create a "Stool' class. Fields: height (h, cm), product quality (low, medium, high). Specify two virtual methods: The "Wood amount" method determines the amount of wood that goes into the stool: 4 • h + 12 if the product quality is low, 5 • h + 14 if the quality is average or high. "Price" method is equal to d • 2 for low quality, d • 3 for medium quality, d • 4 for high quality, where d is the amount of wood required for the object. Also write an "Information" method that prints information about the object: Height, Material Quality, Wood Quantity, and Price. Also create an inheritance class "Chair". Additional area: back height (h2, cm). In the reloaded "Amount of Wood" method, the amount of wood is calculated using the formula d + 2 • h2 + 5.arrow_forwardThe total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…arrow_forward
