Assignment Brief

You have to develop an application to solve a small business problem. The problem requires a graphical user
interface with features that required reading / writing data from text file, working with a collection of data
(searching for item / min / max / sum / etc.). The application must handle errors so that it will not crash at end user
side. The application also need to be fully tested before the production phase.
You need to write a technical report about the development of the application. Content of the report should cover
design, implementation and testing.
In the end you need to demo your application, explain your code and answer technical questions.

Introduction

I am currently a technician at a fairly large restaurant in Ho Chi Minh City. My main task is
to solve the problems that the restaurant is facing by creating a certain system. Now our
restaurant is having a pretty big problem. As follows:
Nowadays, setting the table before eating is a habit that everyone must have, because they do

not want to have trouble clearing the table. Therefore, the demand for online booking and
eating on the spot is increasing day by day. We are not able to record customer booking
information through normal recording. Their main problem is the issue of creating invoices.
Therefore, the owner of the restaurant asked me to create a program system that helps
employees somewhat. Besides, it also helps them quickly receive the information given by
customers more quickly.

Implementation

Implement CommissionEmployee

Explanation:
Figure 11: Code of Commission Employee
-

A form of EMPLOYEE is a COMMISSION EMPLOYEE.
‘Protected’ is often used to represent the traits that we (the designers) wish the
subclasses to inherit.
SetTotalSales(double s) assign the value of the totalSales property to
getTotalSales() can be used to obtain an attribute's value.
Employees who work only on commission are compensated based on the amount of
income they generate for the company. A compensation is a monetary payment made
to a worker when they finish a job or activity for a company. This is usually a
percentage or flat charge deducted from the money coming into the organization.[1]


Implement BasePlusCommission Employee
Explanation:

Figure 12: Code of Base Plus Commission Employee
-

super (): invoke its parent's constructor

baseSalary = baseSa: increase the employee's basic salary amount

Implements Serializable

Figure 13: Implements Serializable
Explanation:
-

This is a law (interface). Items must conform the Serializable system in order to be
written to a drive as entities.
Serialization is a notion that allows us to transfer the value of the a Java object into
such a style that can subsequently be saved and utilized with another operation. [2]

Test

Create new booking

Figure 14: Create new order.
Create customer orders by entering available data and clicking the Create button. Pressing the
newly created button and storing it in the memory of the current computer

Create another order

Figure 15: Create another new order


View customers booked by pressing previous and next

Figure 16: The customer has booked a table

Figure 17: View clients booked by pressing ‘next’ button


By pressing create like the step above, it has stored the customer data and the staff can review
and confirm that information with the customer.
Save all information of booking

Figure 18 Save information of client booking and click (X)

Load all data of client when click turn off app

Figure 19: Click Load all client data to view client
who book a table


Figure 20: Result return for load client data

Conclusion

I overcame the problem the restaurant was having by creating a software that made it easier
for employees to work. At the same time, it also supports to review the customers who have
booked at the restaurant by loading data in the application.
