Create A GUI App For Flooring Cost Calculation

Create a GUI application for flooring cost calculation and database storage

You work for a flooring company and are tasked with developing a GUI-based application to facilitate customer order management. The application must enable users to input customer details, select flooring options, calculate the total flooring area and cost, display order summaries, and store all information in a MySQL database. Additionally, the program should list all existing customer orders stored in the database.

Paper For Above instruction

Developing an intuitive, efficient, and reliable GUI application for a flooring company requires integrating user-friendly interface components with robust backend database management. The core functionalities include collecting customer information and flooring preferences, performing calculations, validating input data, and maintaining a persistent record of all orders. This comprehensive approach ensures high data integrity, ease of use, and effective order tracking.

Design and User Interface Components

The application's user interface should contain a minimum of three tabs to organize functionalities logically. Typically, these tabs can be labeled as "Order Entry," "Order Summary," and "Order List." The "Order Entry" tab provides input fields and options for customer details and flooring selections. The "Order Summary" tab displays calculated details and order details, while the "Order List" tab presents all stored orders from the database in a read-only format.

Input components should include radio buttons for flooring type selection—either "Wood" or "Carpet"—which simplifies user choice. Text fields must be provided for entering customer name and address, along with length and width of the flooring area. Buttons for "Calculate Area," "Calculate Cost," "Submit Order," and "Display Orders" should be implemented for user interactions. The "Calculate Area" and "Calculate Cost" buttons perform respective calculations, while "Submit Order" saves the data to the database, and "Display Orders" lists all existing records.

Functionality and Workflow

The application’s logic begins with input validation. It checks that all required fields are filled, and the length and width inputs are numeric. If validation fails, appropriate error messages guide the user to correct the inputs. Upon successful validation, calculations for the flooring area and cost are performed based on predefined rates: $20 per square foot for wood flooring and $10 per square foot for carpet.

The area calculation multiplies length by width, displaying the result formatted to two decimal places. The cost calculation multiplies the area by the selected flooring rate, also formatted appropriately. These calculations are displayed in the interface for user confirmation. When the user clicks "Submit Order," the application stores the customer name, address, flooring type, calculated area, and cost into the "flooring" MySQL table.

Database Interaction

The database table named "flooring" includes fields for customer name, customer address, flooring type, floor area, and floor cost. When a new order is submitted, the application must insert a new record into this table with accurate data. To retrieve and display all stored orders, a SQL SELECT query fetches all records, which are then presented in a user-friendly list, such as a text area. The list should be read-only and formatted for easy reading.

Implementation Details and Technologies

The application should be developed in Java, utilizing Swing for the GUI components. JDBC (Java Database Connectivity) is used to connect to and interact with the MySQL database. Proper exception handling ensures that database errors or user input mistakes are gracefully managed, providing users with meaningful feedback.

All numeric and currency outputs must be formatted appropriately, for example, using NumberFormat or DecimalFormat in Java, to present values with two decimal places and currency symbols. This enhances readability and professionalism of the output.

Additional Considerations

Ensuring the application is robust involves validating all input data before processing. For example, if length or width are non-numeric or missing, an error message should be displayed, and calculations should not proceed. When displaying the order summary, all relevant details—such as customer name, address, flooring type, area, and cost—should be clearly presented, possibly in a new window or designated section within the tab interface.

To support ease of use, the application should reset input fields after each successful order submission and provide clear labels and instructions on each tab. The design should be minimalistic but informative, aligning with the goal of providing a straightforward user experience for flooring company staff.

Conclusion

In essence, this flooring order management application integrates user input collection, calculation, database storage, and retrieval functionalities within a multi-tab interface. It ensures data validation, formatted output, and easy access to all past orders, thereby streamlining the company's workflow. The robust design, combined with thorough validation and user-friendly components, maximizes operational efficiency and data accuracy.
