- Create a class named Purchase. Each Purchase contains an invoice number (private int), amount of sale (private double), and amount of sales tax (private double). Include set methods for the invoice number and sale amount. Within the set() method for the sale amount, calculate the sales tax as 5% of the sale amount. Also include a display method that displays a purchase’s details (i.e invoice, sale amount and tax). Save the file as Purchase.java. 2. Create an application (with main ()) that declares a Purchase object (using class defined in previous question) and prompts the user if he/she wants to enter an invoice number (1-yes, 0 – no). If user enters 1 then the program will prompt for an invoice number, do not let the user proceed until a number between 1,000 and 8,000 has been entered. Next, the program prompts for a sale amount, do not proceed until the user has entered a nonnegative value. Using the values entered by the user create a Purchase object, display the object’s…arrow_forwardDesign a Book class that holds the title, author’s name, and price of the book. Books’s constructor should initialize all of these data members except the price which is set to 500/-. Create a display method that displays all fields. All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces the Bookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the display method to display all fields. Write a Main () method that declares an array of five Book objects. Ask the user to enter the title and author for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following: Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details.arrow_forwardCreate a class named Person that holds the following fields: two String objects for the person’s first and last name and a LocalDate object for the person’s birthdate. Create a class named Couple that contains two Person objects. Create a class named Wedding for a wedding planner that includes the date of the wedding, the Couple being married, and a String for the location. Provide constructors for each class that accept parameters for each field, and provide get methods for each field.arrow_forward
- Create a class named Grades, which has four fields, one for the name of the student, and three other fields for grades in test1, test2 and test3. The class should contain two constructors: a no-argument constructor that sets all fields to zero, and a constructor that sets all fields to a given value. The class should have the appropriate methods to “set” and “get” the values of all fields. The class should also have a method to calculate the average of the three tests. To test the class, you should create a class demo that instantiates one object of the Grades class and asks the user enter the student name and the grades for the three tests. The program should set the fields to the values entered by the user using the “set” methods, and output to the console the student name, the grades for test1, test2 and test3 as well as their average using “get” methods.arrow_forwardDice Rolling Class In this problem, you will need to create a program that simulates rolling dice. To start this project, you will first need to define the properties and behaviors of a single die that can be reused multiple times in your future code. This will be done by creating a Dice class. Create a Dice class that contains the following members: Two private integer variables to store the minimum and maximum roll possible. Two constructors that initialize the data members that store the min/max possible values of rolls. a constructor with default min/max values. a constructor that takes 2 input arguments corresponding to the min and max roll values Create a roll() function that returns a random number that is uniformly distributed between the minimum and maximum possible roll values. Create a small test program that asks the user to give a minValue and maxValue for a die, construct a single object of the Dice class with the constructor that initializes the min and max…arrow_forwardStatic & Not Final Field: Accessed by every object, Changing Non-Static & Final Field: Accessed by object itself, Non-Changing Static & Final: Accessed by every object, Non-Changing Non-Static & Not Final Field: Accessed by object itself, ChangingRead the following situation and decide how the variables should be defined. You have a class named HeartsPlayerA round of Hearts starts with every player having 13 cardsPlayers then choose 3 cards to “trade” with a player (1st you pass left, 2nd you pass right, 3rd you pass across, 4th you keep)Players then strategically play cards in order to have the lowest scoreAt the end of the round, points are cumulatively totaled for each player.If one player’s total is greater than 100, the game ends and the player with the lowest score wins. 1. How should the following data fields be defined (with respect to final and static)?(a) playerPosition (These have values of North, South, East, or West)(b) directionOfPassing(c) totalScore…arrow_forward
- Create an Automobile class for a dealership. Include fields for an ID number, make, model, color, year, and miles per gallon. Include get and set methods for each field. Do not allow the ID to be negative or more than 9999; if it is, set the ID to 0. Do not allow the year to be earlier than 2005 or later than 2019; if it is, set the year to 0. Do not allow the miles per gallon to be less than 10 or more than 60; if it is, set the miles per gallon to 0. Include a constructor that accepts arguments for each field value and uses the set methods to assign the values.arrow_forwardCreate a class called Point which will have 2 co-ordinate value x & y and will be able to calculate the distance between two points. Write appropriate constructor and method of the class. Create another class called Shape, which takes different number of points to create a triangle, rectangle and circle. And also able to calculate the area and perimeter for the different shapes. Write the appropriate overloading method for this shape class. Write appropriate main function to test the shape class. Note- for code use C++ only .arrow_forwardCreate a class named Purchase. Each Purchase contains an invoice number, amount of sale, and amount of sales tax. Include set methods for the invoice number and sale amount. Within the set() method for the sale amount, calculate the sales tax as 5% of the sale amount. Also include a display method that displays a purchase’s detailsarrow_forward
- Assignment 10: Chapter 10 Complete Programming Challenge 10 at the end of chapter 10 10. Ship, CruiseShip, and CargoShip Classes Design a Ship class that the following members: A field for the name of the ship (a string) - A field for the year that the ship was built (a string). A constructor and appropriate accessors and mutators. A toString method that displays the ship's name and the year it was built. Design a CruiseShip class that extends the Ship class. The CruiseShip class should have the following members: A field for the maximum number of passengers (an int). A constructor and appropriate accessors and mutators. A toString method that overrides the toString method in the base class. The CruiseShip class's toString method should display only the ship's name and the maximum number of passengers. Design a CargoShip class that extends the Ship class. The CargoShip class should have the following members: A field for the cargo capacity in tonnage (an int). A constructor and…arrow_forwardCreate a class named Customer that will determine the monthly repayment amount due by a customer for a product bought on credit. The class has five fields: customer name, contact number, product price, number of months and the monthly repayment amount. Write get and set methods for each field, except for the monthly repayment amount field. The set methods must prompt the user to enter the values for the following fields: customer name, contact number, product price and number of months. This class also needs a method to calculate the monthly repayment amount (product price divided by the number of months). Add a subclass named Finance_Period that will determine if a customer will pay interest or not. If the number of months to pay for the product is greater than three, the customer will pay 25% interest, else no interest applies. The maximum number of months to pay for the product is 12. Override the calculate_repayment () method by determining if the customer will pay interest or not…arrow_forwardThere should only be one constructor for every class. True Falsearrow_forward
