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.
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.
Create a object called Teacher. Declare the following variables for the object: string f_name, string subject, int age and int room_no. Include in the object a default constructor and a parameterised constructor. The parameterised constructor has the following parameters (name and age). Create your main class Teaching. The reference variable for the default constructor is T1 and for the parameterised constructor is T2. Pass the following values for the T1 reference to the default constructor: f_name = John subject = Science age = 35 room_no = 10 Pass the following variable using the T2 reference to the parameterised constructor: name = Smith age = 45 Program must include System.out statements to display the output.

Create a class time24, each object is a value represented the time of day in the form hours, minutes and seconds.Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values in case no initializes are provided.Provide Public member functions for each of the following operations: set the time, print the time, increment the time by one second, compare two times for equality, increment the time by one hour, determine if one time is “less than” (comes before) another time, and final print the time in format 12 hours.Include any additional operations that you think would be useful for your class.Design,implement, and test your class.

For example, if birthmonth=3, birthday=22, birthyear=2000, it should return the String "3/22/2000"Create a public method called verifySSN that takes in a String parameter and returns a boolean. It will check the parameter against the person's SSN and return true or false based on whether they match.

Define a class with the following specifications: Create a class called MarathonRunner that has three private data members: name (String), distance (double) and time (double). a. Write a constructor that accepts name, distance, and time as input parameters to initialize the private data members. b. Provide only one accessor (get) method and one mutator (set) method for the distance data member. c. d. Define a private method called calculateSpeed(0 which calculates and returns the speed (double) of the distance marathon runner. The speed is calculated using the formula: speed = time Define a public method called isFaster() that accepts as input parameter a speed record(double). The method should return true if the current runner's speed is faster than the speed record, otherwise, return false. e. Define a public method called displayDetails() to display on the screen the runner's details as in the f. following
Given the following interface, create a class named Tesla that implements the Car interface. public interface Car { public double speedUp(); public double slowDown(); public String returnCarName(); } Tesla should have the following: Member variable named ‘speed’ of type int Member variable named ‘carName’ of type String Default Constructor and Constructor that accepts the two member variables as arguments The default speed should be 0 The default car name should be ‘Model 3’ To increase the car’s speed, you increment speed by 1 To decrease the car’s speed, you decrement speed by 1 You only need to create the Tesla class. You do not have to use the interface and class in a working program.
