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.
In-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract. Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0 Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: # Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: # Write a TestShape class that has the main method, which creates…
Define a Course base class with the following attributes: number - course number title - course title Define a print_info() method in Course that displays the course number and title. Also define a derived class OfferedCourse with the additional attributes: instructor_name - instructor name location - class location class_time - class time
Class Activity 3 :: Super class and sub class reference types 1. Create a superclass called the person to store the properties such as name and address 2. Create a Subclass Salaried Employee for their specific properties. For salaried Employee - who are paid a fixed weekly salary regardless of the number of hours worked. • To maintain the fixed salary and number of hours worked. • Add a fixed salary. • Print the Salary. Assume that an employee works no more than 8 hours in a day. 3. Create a Subclass Hourly - Salaried Employee for their specific properties. For Hourly - Salaried Employee: - who are paid by the hour and receive overtime pay. • To maintain the hourly salary and the number of hours worked; • Add an hourly_salary and number of hours worked. • Print the Salary. Assume that an employee works no more than 12 hours in a day.
Design a class named Employee. The class should keep the following information infields:• Employee name• Employee number in the format XXX-L, where each X is a digit within the range0-9 and the Lis aletter within the range A-M.• Hire date* Write one or more constructors and the appropriate accessor and mutator methods for theclass.Next, write a class named ProductionWorker that extends the Employee class. TheProductionWorker class should have fields to hold the following information:• Shift (an integer)• Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift field will be an integer valuerepresenting the shift that the employee works. The day shift is shift 1 and the night shift isshift 2. Write one or more constructors and the appropriate accessor and mutator methodsfor the class. Demonstrate the classes by writing a program that uses a ProductionWorkerobject. have to use beginner code because this is an intro class.

Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the account
C# Program Create a class called Employee Requirements:1. Use inheritance2. Use the constructor function to initialize employee information: name, email and mobile number3. Instantiate two employee objects with different information4. Display all properties of both objects
In order to extend a class, the new class should have access to all the data and inner workings of the parent class. True False
is the term used to describe the process of making an instance of one class a member of another.
JAVA Part One: The Member Class Write the class to represent a member. Include the following components: a constant to represent the current year of 2023 instance data variables: a name the year the member joined (stored as an int) whether or not the member is a VIP a constructor that sets all of the instance data variables using parameters getter and setter methods in your setter for the year, use validity checking to make sure the parameter is valid before assigning it to the instance data variable a toString method include the name and year joined in the text representation if the member is a VIP, include that in the text as well you can see my example of the formatting in the sample output below (note that I used tabs in my formatting) You should iteratively write, compile, and test each of these components while writing your class to make sure each works before moving on. Part Two: Class Method Write a method that determines whether a member is a "founding…
15. Suppose the class Employee is declared as follows: public class Employee { private String name; private double baseSalary: public void setName(String newName) {...} public void setBasSalary(double newSalary){...} public String getName() {...} public double getSalary({...} } a)Declare a class Manager that inherits from the class Employee and adds an instance variable bonus for storing a salary bonus. Omit constructors and methods. ANS: b) Which instance variables does the Manager class have? c) In the manager class, provide the method overrides the getSalary method from the class Employee so that it returns the sum of the salary and the bonus d) Based on the above question, which methods does the manager class inherit? e) In the manager class, override the getName method so that managers have a before their name (such as *John Smith).
