Concept explainers
Write a constructor for the class ScienceFairProjectRating, as described in Exercise 10 of the previous chapter. Give this constructor three parameters corresponding to the first three attributes that the exercise describes. The constructor should give default values to the other attributes.

- Why is it important for a class to have a destructor implemented? With your comment, fill in the spaces.arrow_forwardProgram thisarrow_forwardDefine a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…arrow_forward
- 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. To test…arrow_forwardWrite a graphical application that contains a class named RV whose objects are the recreational vehicle designed and digitized as described in Knowledge Exercises 20 and 21 (you can design your version as well. Simple car shape is will be appreciated. The class’s private data members should be the vehicle’s body color and (x, y) location. a) Give the UML diagram for the class. It should include a three-parameter constructor, a toString method, a method to input the values of all of an object’s data members, and a show method to draw the RV at its current (x, y) location. b) Progressively implement and test the RV class by adding a method and verifying it before adding the next method. A good order to add the methods to the class is the three-parameter constructor, followed by the toString method, the show method, and finally the inputmethod. The client code should create an RV object using the three-parameter constructor to test all of the methods as they are progressively added to the…arrow_forwardComplete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) 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…arrow_forward
- In this exercise, you are going to be working with 4 classes, a Book superclass with TextBook and Novel subclasses, and a BookTester class to run your program. For the Book, TextBook, and Novel class, you will create a constructor and all getters and setters. Be sure to follow standard naming conventions for your getters and setters! Additional information for each class is below. Book Class The Book class will have a title and author as instance variables and the constructor should follow this format: public Book(String title, String author) TextBook Class The TextBook class will have a subject and edition as instance variables and the constructor should follow this format: public TextBook(String title, String author, String subject, String edition) Novel Class The Novel class will have a genre and pages as instance variables and the constructor should follow this format: public Novel(String title, String author, String genre, int pages) BookTester In the tester class, you should…arrow_forwardFor this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction.Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…arrow_forwardFor this assignment you will be building on the Fraction class you began last week.
