Write a program named SalespersonDemo that instantiates objects using classes named Real EstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full nameâ€”the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.
Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.
Chapter 10 defined the class circleType to implement the basic properties of a circle. (Add the function print to this class to output the radius, area, and circumference of a circle.) Now every cylinder has a base and height, where the base is a circle. Design a class cylinderType that can capture the properties of a cylinder and perform the usual operations on the cylinder. Derive this class from the class circleType designed in Chapter 10. Some of the operations that can be performed on a cylinder are as follows: calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Also, write a program to test various operations on a cylinder.
Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…
Create a base class called “Animal” which has two (2) class fields. The first field holds an integer “IDtag” for a number that a zoo uses to catalogue their animals and the second field holds a string called “species.”From the Animal class, derive two (2) classes. One is called “Bird” and the other “Reptile”. E.g. Species could be (for the Bird class) ostrich, dove, chicken etc. and (for the Reptile class) lizard, snake, bearded dragon etc.The Bird class has an additional class field called “colour” which holds the colour of the birds feathers (int – 1=grey, 2=white, 3=black). The reptile class has an additional class field called “bloodTemp” which hold the reptile’s temperature of their blood (double).You need to instantiate two (2) objects. The bird object will be called “brd” and the reptile object called “rept.”Input values for the bird’s IDtag, species and feather colour (int) and for the reptile’s IDtag number, species and bloodTemp. Override the Animal class’s input and output…
Given the following code for the base class Ship write another class that inherits from Ship called SpaceShip. Spaceship should have a field to store forwardLasers(an integer) and aftMineDispensers (another integer). You should provide a constructor that includes forwardLasers as an argument. You should have another constructor that includes both forwardLasers and aftMineDispensers as arguments. You should provide appropriate accessors and mutators. You should include a toString() method that prints out the forwardLasers and aftMineDispensers as well as the information from the super class toString(). Here is the code for the base class Ship. public class Ship { private String name; // Ship name private String yearBuilt; // Year it was built public Ship(String n, String y) { name = n; yearBuilt = y; } public void setName(String n) { name = n; } public void setYearBuilt(String y) { yearBuilt = y; } public String getName() { return…
1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.
In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile. Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program. You can Fork the program to make your own version in Replit, where you can add your Tile.java, or you can copy the program to your own Java development…
Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the value you assigned.
Step 3: Add a basic WineCase class and allow a buyer to select a case of wine to buy. Write a basic WineCase class to represent a case of wine. A WineCase object has four fields: refNo (a unique sequence of letters and digits), description (e.g. "chablis", "white burgundy" or similar), noOfBottles (in the case) and price (the price of the case in pounds). The constructor for the class should be passed suitable arguments to initialise these four fields. Add a selectWineCase() method to the Browser class which allows a browser to choose a case of wine provided that browser is a buyer. This method is passed a WineCase object as a parameter. You should declare a new field wineCase in the Browser class in order to store the case of wine selected. Make the selectWinecase() method print a message to the terminal window about the selection. An example is shown below: Buyer with ID 6732 has selected wine case with reference number LO786, a case of 2018 Pinot…
