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.
a) Write the declaration for class B. The members of the class should be as follows: m, an integer. This variable should not be accessible to code outside the class or to any class that extends class B. n, an integer. This variable should be accessible only to classes that extends class B or are in the same package as class B. setM, getM,setN, getN. These are the mutator aand accessor methods for the member variables m and n. These methods should be accessible to code outside the class. calc. This is a public abstract method. b) Write a declaration for class D, which extends class B. The members of the class are as follows: q, a double. This variable should not be accessible to code outside the class. r, a double. This variable should be accessible to any class that extends class D or is in the same package. setQ, getQ,setR, getR. These are the mutator aand accessor methods for the member variables q and r. These methods should be accessible to code outside the class. Calc, a…
The base class Pet has attributes name and age. The derived class Dog inherits attributes from the base class Pet class and includes a breed attribute. Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute. Ex: If the input is: Dobby 2 Kreacher 3 German Schnauzer the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer code to be used: python class Pet: def __init__(self): self.name = '' self.age = 0 def print_info(self): print('Pet Information:') print(' Name:', self.name) print(' Age:', self.age) class Dog(Pet): def __init__(self): Pet.__init__(self) self.breed = '' my_pet = Pet()my_dog = Dog() pet_name = input()pet_age = int(input())dog_name = input()dog_age =…

Task 3 question: Write code in Java with all these classes implementation and a program called Polymorphism_works with member method specific_Item which takes one instance of Item_in_Stock class as a parameter. Perform functionality of adding items, selling items and changing item price and displaying items details against specific item instance. There should be a main () method which declares an array of objects containing instance of sub classes of Item_in_Stock class and then calls methods of each of the implemented classes. More info: In this last and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop…

1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.
Description: Create a class named ComparableDog that extends Animal and implements Comparable interface. Implement the compareTo method to compare the Dogs on the basis of age. Write a test class to find the bigger age of two instances of ComparableDog Objects, and complement the ComparableDog class with the missing part. 1) The test program, the ComparableDog class, and its super class Animal are given as follows. // Main method public static void main(String[] args) { // Create two comparable Dogs ComparableDog dog1 = new ComparableDog(3); ComparableDog dog2 = new ComparableDog(4); System.out.println("Dog1:" + dog1); System.out.println("Dog2:" + dog2); if(dog1.compareTo(dog2) == 1) System.out.println("Dog1 is older than Dog2"); else if(dog1.compareTo(dog2) == -1) System.out.println("Dog1 is younger than Dog2"); else System.out.println("Dog1 and Dog2 have the same age"); }…
Write a java program that declares two classes. The parent class is called Simple that has two data members num1 and num2 to store two numbers. It also has four member functions. • The add() function adds two numbers and displays the result. • The sub() function subtracts two numbers and displays the result. • The mul() function multiplies two numbers and displays the result. • The div() function divides two numbers and displays the result. The child class is called VerifiedSimple that overrides all four functions. Each function in the child class checks the value of data members. It calls the corresponding member function in the parent class if the values are greater than 0. Otherwise it displays error message
Programming Language = Python 1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: • Employee name • Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • Shift number (an integer, such as 1, 2, or 3) • Hourly pay rate The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object and then use the object’s accessor methods to retrieve it and display it on the…
Write a class Distance which has two private data members (int feet,float inches). The class has three constructors which are having no parameter - values of both feet and inches are assigned zero. having two numbers as parameters - the two numbers are assigned as feet and inches respectively. having one number as parameter - both feet and inches are assigned that number. Provide getters and setters for data members. Now write a main class which demonstrate the functionality of above class by calling all constructors, setters & getters. Create 1 object using default constructor, and use setters to set values, then getters to print values. Create a second object using constructor having two parameters, provide values, then print values on screen. Create third object by using third constructor having one parameter, after that print values on screen.
In Java, Write a line of code that performs each of the following tasks : (a) Call superclass Employee's toString method from subclass Pieceworker's toString method. (b)Specify that class Pieceworker inherits from class Employee. (c) Call superclass Employee's constructor from subclass Pieceworker's constructor - assume that the superclass constructor receives three strings representing the first name, last name and social security number.
