Interfaces, Abstract Classes, Inheritance
Create a new Java project in your Eclipse workspace named: Lab07 In the src folder, create a package named: edu.ilstu.it275.lab07. This lab will be improving the implementation of the Lab 06, adding an interface and an abstract base class. First, create an interface called Payment.java which will contain a method named paymentDetails that outputs an English sentence to describe the amount of the payment. Next, create a class called BasePayment.java that implements the Payment interface and which will contain an attribute of type double that stores the amount of the payment and appropriate accessor and mutator methods. In addition to the default constructor, provide a constructor that receives the payment amount. Do Not implement the paymentDetails method in this class. Next, create a class called CashPayment.java that is derived from the BasePayment class. Implement the paymentDetails method to indicate that the payment is in cash. Provide appropriate constructor(s). Next, create a class called CreditCardPayment.java that is derived from the BasePayment class. This class should contain the attributes for the name on the card, expiration date (as a String), and credit card number (as a String) as well as appropriate accessor and mutator methods. Implement the paymentDetails method to include the credit card information in the printout.
