Design a SuperClass named Person with fields for holding a person's name, address, and phone number. Write one or more constructors and the appropriate mutator and accessor methods for the class's fields. Next, design a SubClass which inherit from the Person class. The Customer class should have a field for a customer number and boolean field indicating whether the customer wishes to be on a mailing list. Write one or more constructors and the appropriate mutator and accessor functions for the classes' fields. Third, design a SubClass which inherits from the Customer class. The PreferredCustomer class should have fields for the amount of the customer's purchases and the customers' discount level. Write one or more constructors and the appropriate mutator and accessor functions for the classes'

Create a parent class Person with one attribute age and one method greet() that prints out "Hello, world!". By default, the age is 20. Then create a subclass CollegeStudent that inherits from Person and has its own attributes School_Name and Major. Then create an object (a college student, his name is Harry, age is 21, School_Name is "Felician University", and Major is "Computer Science"), then let Harry say"Hello World!".

Write the abstract super class Transaction, and two of its subclasses, Payment and Sale (you do not need to supply any comments other than your name). I. Write an abstract superclass encapsulating a Transaction: The Transaction super class has an instance variable representing the customers name, and 3 methods: an overloaded constructor, a toString() method that returns a message including the name of the customer, and an abstract method called calculateAmount()which will be implemented in your subclasses. II. Write a non-abstract subclass that inherits from the Transaction class encapsulating a Payment: The Payment class has instance variable representing the payment amount received and 3 methods. It has an overloaded constructor, a toString() method that returns a message including customers name, the name of the class Payment, and the payment amount, an non-abstract class called calculateAmount() which returns the payment amount.

If the programmer doesn't declare any constructors for an extended class, what constructors will be inherited from the superclass? How does this inherited constructor initialize new instance variables that are not part of the superclass? Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables. Suppose you write a new constructor for an extended class. Describe two different ways that the superclass's instance variables could be initialized within the constructor for the extended class.
