Objective: The objective of this assignment is to understand and practice abstract factory pattern.

Assignment Specification: Consider the problem of writing a tax processing program which handles the case of calculating the provincial taxes for Ontario and Quebec. The application works as follows: (50 marks)

1. Display an object of the JFrame class as given below. The supplied application (uploaded in Blackboard) gives the actual code I used. You do not need to pay a lot of attention to the code since it is not relevant to the task you have. I have not attempted to deal with other details (such as error handling). Fig 1(a) shows the initial frame displayed.

2. The user has to fill in all details and press Enter after supplying the yearly income. Fig 1(b) shows a typical frame after the user has entered all details and before the user presses Enter.

3. The program calculates the tax payable in that province and displays a letter to be sent to the user. The frame after the user presses Enter is shown in Fig 1(c).

4. The final frame after entering information about a person from Quebec is shown in Fig 1(d).

Using the idea of Abstract factory pattern (see Fig 2) and rewrite the application. Please note that you will not get any credit if you do not use the Abstract factory pattern in solving the proble
