JAVA
Please help asap, having trouble figuring this out and it is due tonight.
Write the abstract super classTransaction, and two of its subclasses,Payment andSale
(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.
III. Write a second non-abstract subclass that inherits from the Transaction class encapsulating a Sale:
The Sale class has 2 instance variables representing the price and quantity of the sale and 3 methods.
- It has an overloaded constructor,
- a toString() method that returns a message including the customers name, the name of the class Sale, plus the price and quantity of the sale.
- calculateAmount() which returns the total amount of the sale (quantity times price, with an eight and a-half percent sales tax).
IV. Write a client program which instantiates 3 objects of your subclasses and stores them in an array ofTransactionobjects or anArrayList ofTransaction objects. Your client program should process your array orArrayListcalling the toString()followed by the calculateAmount( ) methods which will print the contents of the array.
Sample Program Output:
Bob Jones Sale 19.95 1
Total Amount: $ 21.65
Jane Doe Payment 150.87
Total Amount: $ 150.87
Jack Torance Sale 50.00 2
Total Amount: $ 108.50
