This should be written in a concise, formal business style using single spacing and font size 12. You are required to make use of headings, paragraphs and subsections as appropriate, and all work must be supported with research and referenced using the Harvard referencing system. Please also provide a bibliography using the Harvard referencing system.
Unit Learning Outcomes LO1 Understand basic programming skills and OOP paradigm LO2 Understand how to detect errors and handle errors LO3 Understand how to working with files in applications LO4 Understand how to build GUI application 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.

1. Introduction:
- Product and sales management has never been a simple matter for companies as well
as small shops. So in this assignment, I made a software to make product management
as well as sales simpler.
- Product management in the store is to manage the number of products available, the
price of each product, etc
- In product management, there are many products with different prices. The “Product
Management” program covers many areas such as product code, product name,
product quantity, and cost of each product type.
2. Requirement:
- Create Invoice
- Add, remove product updates
- Export product list
Export invoice list
- Import product list
- Import invoice list
3. UI design:
- Sale UI:
- Storage UI:

4. Implementation:
- Program structure:
- Package declaration: In Java, classes can be stored in several directories or
packages according to the module they are used in. An absolute path from the
source directory is regarded as a package declaration for all the classes that are
contained in a single parent source directory.
- Import statements: There are many classes produced by people, corporations,
etc. that might be beneficial in our application, and there may be classes
written in other folders or packages of our active Java project. We must import
the class we want to utilize in order to use them in it. Multiple import
statements can be made since numerous classes can be imported into a single
application.
- Comments: In Java, the comments can be used to explain a variable, function,
class, or any other statement. The program code may also be temporarily
hidden using this technique.
- Class Definition: A class in a java file has to be given a name. This name is used
in other classes or programs when generating a class object.
- Variables: A Java application's main method is where execution begins. It is, in
other words, a point of entry for a class or application that launches during
Java Run-time.
- Methods/Behaviors: a group of instructions that together make up a
functional component that may need to be executed more than once when a
program is being performed. The instructions are included in a method so that
they are not repeated when the same functionality is needed. By providing
variables to a method, one may manipulate the behavior of the method.

- Classes:
- Store_view:
✓ CircleKView class is responsible for direct interaction with the user
- SaleController:
✓ SaleController class is responsible for receiving requests from users and
using SaleModel and CircleView to process and return results to users.
- SaleModel:
✓ SaleModel class is created to hold object information (Data), interact
with Database. Responsible for object modeling.
- Important algorithms:
- The most important algorithm used in software is the algorithm used for
querying as well as modifying data on the database.
- How to handle errors:
- Since the software is written entirely in java language, I used the try-catch block
to catch exceptions when the program was executed.
