(Triangle class) Design a new Triangle class that extends the abstract Geometricobject class. Draw the UML diagram for the classes Triangle and Geometricobject then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filed. The program should create a Tri- angle object with the se sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.

Problem (Online Address Book): 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. 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 with following members and methods: firstname, lastname, and accessors and mutators, print to display, and constructors.  Define a class dateType for month, day and year as members with its accessors, mutators, and constructors) Design a 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.…

(The Person, Student, Employee, Faculty, and Staff classes) Design a class named Person and its two subclasses named Student and Employee. Make Faculty and Staff subclasses of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). Define the status as a constant. An employee has an office, salary, and date hired. Use the MyDate class defined in Programming Exercise 10.14 – see the textbook - to create an object for date hired. A faculty member has office hours and a rank. A staff member has a title. Override the toString method in each class to display the class name and the person's name. Draw the UML diagram for the classes and implement them. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() methods.

(Account class)Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type int to represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display an error message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add an amount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged, and the function should print a message indicating "Debit amount exceeded account balance." Member function get_Balance should return the current balance. Create a program that creates two Account objects and tests the member functions of class…

Assume all accounts have the same interest rate.  Make it static. ■ A private Date data field named dateCreated that stores the date when the account was created.  (private Date dateCreated)…

(Algebra: quadratic equations) Design a class named QuadraticEquation for a quadratic equation ax² + bx + x = 0. The class contains: 1 The private data fields a, b, and c that represent three coefficients. 1 A constructor for the arguments for a, b, and c. 1 Three get methods for a, b, and c. A method named getDiscriminant() that returns the discriminant, which is b? – 4ac. The methods named getRoot1() and getRoot2() for returning the two roots of the equation using these formulas: -b + Vb? – 4ac -b - Vb? – 4ac and r2 2a 2a These methods are useful only if the discriminant is nonnegative. Let these meth- ods return 0 if the discriminant is negative. Draw the UML diagram for the class, and then implement the class. Write a test program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display "The equation has no…

(Default Constructor) What’s a default constructor? How are an object’s data members initialized if a class has only an implicitly defined default constructor?
