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.
Create a class that represents an employee. This class will have three constructors to initialize variables. If the constructor doesn't provide a parameter for a field, make it either "(not set)" or "0" as appropriate.

1. Write JavaScript function that will serve as a constructor for Rectangle object with two data properties width and length. Add method to the rectangle object that will compute and return the area of the rectangle. 2. Write Javascript function that will take as an input a string and check if that string contains letters a, b, c (disregarding case) in order but not necessarily adjacent. The function should return either true or false and needs to use regular expressions. here are some examples of strings that should return true: abc danmhblkoc aabbc adagbkbiuc abca And, here are some strings that should return false: dgk dakl cba abac.
Part A Create a class named JobApplicant that holds data about a job applicant. Include a name as name, a phone number as phone, and four Boolean fields that represent whether the applicant is skilled in each of the following areas: word processing as hasWordSkill, spreadsheets as hasSpreadsheetSkill, databases as hasDatabaseSkill, and graphics as hasGraphicsSkill. Include a blank constructor that takes no arguments and an overloaded constructor that accepts values for each of the fields. Also include a get method for each field. Part B Create an application called TestJobApplicants that instantiates three JobApplicant objects in the main() method. Pass each object, in turn, to a method called getData() that gets user data for each field: the user enters Strings for the name and phone number, and enters four integers that indicate whether the applicant possesses each of the four skills. Return a complete JobApplicant object to the main() method. After the objects are returned to the…
Write a tester program to test the mobile class defined below. Create the class named with your id (use : Id 190099306) with the main method. Create two mobiles M1 and M2 using the first constructor. Print the characteristics of M1 and M2. Create one mobile M3 using the second constructor. Change the id and brand of the mobile M3. Print the id of M3. Your answer should include a screenshot of the output. public class Mobile { private int id; private String brand; public Mobile() { id = 0; brand = ""; } public Mobile(int n, String name) { id = n; brand = name; } public void setBrand(String w) { brand = w; } public void setId(int w) { id = w; } Public int getId() { return id; } public String getBrand() { return brand; } } please provide me how to do the steps and i will try to work it alone. we didn't study this excersie in the lab

QI. Write a program in BlueJ using the following hints. 1. Create a class named Book and declare the fields author, title and pages with suitable field types. 2. Declare the constructor and initialize the fields author and title with the assigned constructor parameter. 3. Name the constructor parameter as your own. 4. Add two accessor methods to the class getAuthor, getTitle and getPages—that return the author and title fields as their respective results. Add mutator method to change the pages of the Book class. 5. Add two methods, printAuthor and printTitle, to this Book class project. These should print the author and title fields, respectively, to the terminal window.
