NIT2112 - Object Oriented Programming - Coffee N Roll Sandwich Shop - GUI Application - Computer Science Assignment Help

Assignment Task:

Problem Description Coffee N Roll is a small-town Sandwich Shop in rural Australia. The population is small so the Sandwich Shop sells only small but select gourmet products. It sells five products only. Each product has a name and a price. 

The programming team requires to demonstrate basic Java programming techniques, specifically using classes and objects. The aim of this assignment is to develop a top-down design and to write a program to be used as a cash register by the Coffee N Roll Sandwich Shop. 

The assignment is composed of two parts. In Part 1, you are to write a Command Line Interface (CLI) cash register application and in Part 2 you create a Graphical User Interface (GUI) for the same cash register. 

Part 1 Application Requirements For our Java program simulation, a purchase transaction is sold and payment of a single product. For each sale, the program should prompt and get a numbered item corresponding to the product name and quantity of the product purchased. The total cost of the purchase should be calculated and displayed. Then the program should ask the amount of money paid by the customer. The calculated change will be displayed in dollars and cents as well as the currency denominations in banknotes and coins needed to make up the change in the most efficient way .

At the end of the day, the cashier enters Done to end the simulation. The program should then display the total amount of sales in each of the five categories and terminate

What do you have to hand in? An electronic copy of 

1. Readme.docx file with information on how to run your program. Include any extra information about your design and program that you wish the marker to know. 

2. Summary of task allocations—who did what? 

3. A word document with the evidence of trial runs of your program, i.e., jGRASP console output for CLI app or screen printouts of GUI results where you have tested all the features of your code.

4. UML diagram for all classes in your program. 

5. Code for all the classes that have been compiled and are ready to run. (jGRASP will be used to run and test your application). 

6. A brief description of the class. At the start of each method, there should be a comment clearly describing what the method does.
