Chapter 6, Problem 10E
In the previous chapter, Self-Test Question 16 described a class Person to represent a person. The class has instance variables for a person’s name, which is a string, and an integer age. These variables are name and age, respectively.
- a. Write a default constructor for Person that sets name to the string “No name yet” and age to zero.
- b. Write a second constructor for Person that sets name to a given string and age to a given age.
- c. Write a static method createAdult for Person that returns a special instance of this class. The instance represents a generic adult and has the name “An adult” and the age 21.

You are asked to write a discount system for a beauty saloon, which provides services and sells beauty products.
It offers 3 types of memberships: Premium, Gold, and Silver. Premium, gold and silver members receive a discount of 20%, 15%, and 10%, respectively, for all services provided. Customers without membership receive no discount. All members receives a flat 10% discount on products purchased (this might change in the future).
Your system shall consist of three classes: Customer, DiscountRate and Visit, as shown in the class diagram. It shall compute the total bill if a customer purchases $x of products and $y of services, for a visit. Also, write a test program VisitDriver (are not to be graded and optional) to exercise all the classes.
Important: "Visit Class diagram - ERROR"
Constructor method of Visit class must recieve Customer object instead of String name.

Can you call a constructor from another constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first.
Problem Statement#
A class can have multiple parameterized constructors which can call each other.
You are given a partially completed code of a Car class in the editor. Modify the parametrized constructor which assigns parameters to the required fields.
Input#
carName, carModel, carCapacity
Output#
carName, carModel, carCapacity
Sample Input#
"Ferrari", "F8", "100"
Sample Output#
"Ferrari", "F8", "100"
Part of solution

- Use this exercise to test your code that you wrote in the previous exercise. Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2 + 5 = Your class needs to contain two constructors, one that takes String, int, int that represents the operator sign(+, -, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem.

- Complete 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_forwardConsider the following Student Class An.
