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.
Some of the characteristics of a book are the title, author(s), publisher, ISBN, price, and year of publication. Design a class bookType that defines the book as an ADT. Each object of the class bookType can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock. To keep track of the number of authors, add another member variable. Include the member functions to perform the various operations on objects of type bookType. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is the same as the actual title of the book. Similarly, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock. Add similar operations for the publisher, ISBN, book price, and authors. Add the appropriate constructors and a destructor (if one is needed). Write the definitions of the member functions of the class bookType. Write a program that uses the class bookType and tests various operations on the objects of the class bookType. Declare an array of 100 components of type bookType. Some of the operations that you should perform are to search for a book by its title, search by ISBN, and update the number of copies of a book.
Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.
Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
Inheritance Create a base class called Shape with two final variables: PI and shapeType. PI should be set to 3.14159 and shapeType should be a String that indicates the type of shape. Create a subclass called Circle that extends Shape. Circle should have an instance variable called radius and a constructor that initializes radius. Override the toString() method to display the details of the circle, including its shape type, radius, and area. Create another subclass called Rectangle that extends Shape. Rectangle should have two instance variables called length and width, and a constructor that initializes length and width. Override the toString() method to display the details of the rectangle, including its shape type, length, width, and area. In the main method, create objects of Circle and Rectangle and call their toString() methods to demonstrate inheritance and the use of final variables.
Define a new "Exam" class that manages the exam name (string) and its score (integer). For example, an exam can have - "Midterm Exam", 100 - "Final Exam", 50 The class must not provide the default constructor. It must require the exam name and score in order to initialize the Exam object. The class must provide only the following methods (no more and no less): - isPerfect method that returns true if the score is exactly 100 and false otherwise. - isPassing method that returns true if the score is equal or greater than 70 and false otherwise. - toString method must return all the exam information including the result of the exam as a string in the following format: EXAM(<name>) SCORE(<score>) RESULT(Pass/Fail) such asEXAM(Midterm Exam) SCORE(100) RESULT(Pass) EXAM(Final Exam) SCORE(50) RESULT(Fail) "Pass" means the score is greater or equal 70. "Fail" is whenever the score is below 70. - isGreater method that compares with another Exam object and return true if the score…

Design a class named Month. The class should have the following private members: • name - A string object that holds the name of a month, such as "January", "February", etc. • monthNumber - An integer variable that holds the number of the month. For example, January would be 1, February would be 2, etc. Valid values for this variable are 1 through 12. In addition, provide the following member functions: • A default constructor that sets monthNumber to 1 and name to "January." • A constructor that accepts the name of the month as an argument. It should set name to the value passed as the argument and set monthNumber to the correct value. • A constructor that accepts the number of the month as an argument. It should set monthNumber to the value passed as the argument and set name to the correct month name. • Appropriate set and get functions for the name and monthNumber member variables. • Prefix and postfix overloaded ++ operator functions that increment…
Part 1: Design a Class You’ll design a class named Car that has the following fields: yearModel—An Integer that holds the car’s model year make—A String that holds the make of the car speed—An Integer that holds the car’s current speed The class should have the following constructor and other methods: The constructor should accept the car’s model year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Design appropriate accessor methods to get the values stored in an object’s yearModel, make, and speed fields. The accelerate method should add 5 to the speed field each time it’s called. The brake method should subtract 5 from the speed field each time it’s called. Create your class in a plain-text editor such as Notepad or TextEdit and save as a text file (*.txt). Part 2: Design a Program You’ll create both a pseudocode and you will create a flowchart to design a program that…
