Using classes, design an online address book to keep track of the names, addresses, phone numbers, and birthdays of family members, close friends and certain business associates. Your program should be able to handle a maximum of 10 entries. For that, (10) • Define the class Address that can store a street address, city, state, and zip code. Use the appropriate methods to print and store the address. Also, use constructors to automatically initialize the data members. • Define the class Person and its attributes. Add a data member to this class to classify the person as a family member, friend, or business associate. Also, add a data member to store the phone number. You must Add (or override) methods to print and store the appropriate information. Use constructors to automatically initialize the data members. • Now, Define the class AddressBook using previously defined classes. • The program should perform the following operations: o Load the data into the address book. o Search for a person by last name. o Print the address, phone number, and date of birth (if available) of a given person.

Refer to the following interface:     Provide two examples (screenshots) that in many ways could improve the above or similar interface using the principles of direct manipulation. Explain the relevant improvements as well. (Examples might have different object, labels and organization)

MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM.

For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction. Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…

JAVA QUESTION REQUIRES SEPARATE CLASSES, CANNOT BE WRITTEN IN ONE MAIN METHOD E.G. ACCOUNT SECTION WRITTEN IN ACCOUNT CLASS, CUSTOMER SECTION WRITTEN IN CUSTOMER CLASS ETC. Phase 2 In this phase you’ll be writing code within the methods of your classes to make the tests pass. Account Each account should have a constant, unique id. Id numbers should start from 1000 and increment by 5. The ACCOUNT_ID attribute should be initialised when the account object is created. The id should be generated internally within the class, it should not be passed in as an argument. The deposit method should increase the balance by the value passed in as an argument. The withdraw method should reduce the balance by the value passed in as an argument. It should return the value of the argument The account should be able to go overdrawn The correctBalance method should change the balance to match the value passed in as an argument. Testing your code for Account Run TestAccountInitialisation to check…

Do not remove this question theirs no reason to. It follows all the guidelines. If you need more information just ask. Code in Java and post the entire finished program with UML and algorithm.Create and implement a set of several classes (nine minimum) that define various types of vehicles in an auto dealership’s own inventory displaying Inheritance and Polymorphism. Please include data values that describe various attributes belonging to each vehicle like the year, make, and model. Also make a main driver class that instantiates and exercises several of the classes. Include pseudocode for each line. Include an algorithm and a simple UML diagram and write in your pseudocode specifically where the algorithm is. The output should include all the given information, make, model, year and an explenation of what the program does.

3. Design a user-defined class called Course. Each course object will hold data about a course. The data includes courseID, courseName, credits and instructorName. Define the instance variables required of the appropriate type. Provide only get methods along with toString() and equals() methods. Design another user-defined class called Student. Each student object will hold data on name, GPA and courseList. Make sure to define courseList as an ArrayList holding references to Course objects Implement a constructor that will take values to initialize name, and gpa while courseList is initialized to an ArrayList() object. Provide the following get methods: getStudent ID ( ), getName(), getGPA (), get Gender(), and get CourseList() Note: the getCouresList() method will return a copy of the coureList arraylist with copies of course objects. Provide the following set methods: setName(), setGPA (), setGender() Another method: addCourse () that will take a Course object and add it to the…

Choose necessary patters, draw the UML and code just company class methods on paper. A car company makes a car produce application. There are diffrerent types of models that the company builds as sedan  and sport. Each model has some shared and distinguishing features. The object creation process should conduct by a central class. The second central class should not be created in the application.

2 part question I am using eclipse! Create a class Circle, which - has a field radius (double) It should have appropriate accessor and mutator.   If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value.   The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects.   This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level.   Note: Area = Pi * radius * radius Perimeter = 2 * Pi * Radius   part 2 Create a subclass of Circle class ColoredCircle by implementing the ColoredShape interface. It should have a field color of type enum ShapeColor. ColoredShape.java ShapeColor.java  ColoredCircle should have two constructors. One will takes one parameters radius and set the color to…
